Microalbumin Creatinine Ratio: MedlinePlus Lab Test Information

 

What is a microalbumin creatinine ratio?

Microalbumin is a small amount of a protein called albumin. It is normally found in the blood. Creatinine is a normal waste product found in urine. A microalbumin creatinine ratio compares the amount of albumin to the amount of creatinine in your urine.

If there is any albumin in your urine, the amount can vary greatly throughout the day. But creatinine is released as a steady rate. Because of this, your health care provider can more accurately measure the amount of albumin by comparing it to the amount of creatinine in your urine. If albumin is found in your urine, it may mean you have a problem with your kidneys.

Other names: albumin-creatinine ratio; urine albumin; microalbumin, urine; ACR; UACR

What is it used for?

A microalbumin creatinine ratio is most often used to screen people who are at higher risk for kidney disease. These include people with diabetes or high blood pressure. Identifying kidney disease at an early stage can help prevent serious complications.

Why do I need a microalbumin creatinine ratio?

You may need this test if you have diabetes. The American Diabetes Association recommends:

If you have high blood pressure, you may get a microalbumin creatinine ratio at regular intervals, as recommended by your health care provider.

What happens during a microalbumin creatinine ratio?

For a microalbumin creatinine ratio you will be asked to provide either a 24-hour urine sample or a random urine sample.

For a 24-hour urine sample, you will need to collect all urine passed in a 24-hour period. Your health care provider or a laboratory professional will give you a container to collect your urine and instructions on how to collect and store your samples. A 24-hour urine sample test usually includes the following steps:

  • Empty your bladder in the morning and flush that urine down. Do not collect this urine. Record the time.
  • For the next 24 hours, save all your urine passed in the container provided.
  • Store your urine container in the refrigerator or a cooler with ice.
  • Return the sample container to your health provider’s office or the laboratory as instructed.

For a random urine sample, you will receive a container in which to collect the urine and special instructions to ensure the sample is sterile. These instructions are often referred to as the “clean catch method.” The clean catch method includes the following steps:

  • Wash your hands.
  • Clean your genital area with a cleansing pad. Men should wipe the tip of their penis. Women should open their labia and clean from front to back.
  • Start to urinate into the toilet.
  • Move the collection container under your urine stream.
  • Collect at least an ounce or two of urine into the container, which should have markings to indicate the amount.
  • Finish urinating into the toilet.
  • Return the sample container as instructed by your health care provider.

Will I need to do anything to prepare for the test?

You don’t need any special preparations for a microalbumin creatinine ratio.

Are there any risks to the test?

There is no known risk to a 24-hour urine sample or a random urine sample.

What do the results mean?

If your microalbumin creatinine ratio shows albumin in your urine, you may get tested again to confirm the results. If your results continue to show albumin in urine, it may mean you have early-stage kidney disease. If your test results show high levels of albumin, it may mean you have kidney failure. If you are diagnosed with kidney disease, your health care provider will take steps to treat the disease and/or prevent further complications.

If small amounts of albumin are found in your urine, it doesn’t necessarily mean you have kidney disease. Urinary tract infections and other factors can cause albumin to show up in urine. If you have questions about your results, talk to your health care provider.

Is there anything else I need to know about a microalbumin creatinine ratio?

Be sure not to confuse “prealbumin” with albumin. Although they sound similar, prealbumin is a different type of protein. A prealbumin test is used to diagnose different conditions than a microalbumin creatinine ratio.

Porphyrin Test: MedlinePlus Lab Test Information

 

What are porphyrin tests?

Porphyrin tests measure the level of porphyrins in your blood, urine, or stool. Porphyrins are chemicals that help make hemoglobin, a type of protein in your red blood cells. Hemoglobin carries oxygen from your lungs to the rest of your body.

It’s normal to have a small amount of porphyrins in your blood and other body fluids. But too much porphyrin may mean you have a type of porphyria. Porphyria is a rare disorder that can cause serious health problems. Porphyria is usually divided into two categories:

  • Acute porphyrias, which mainly affect the nervous system and causes abdominal symptoms
  • Cutaneous porphyrias, which cause skin symptoms when you are exposed to sunlight

Some porphyrias affect both the nervous system and the skin.

Other names: protoporphyrin; protoporphyrin, blood; protoporhyrin, stool; porphyrins, feces; uroporphyrin; porphyrins, urine; Mauzerall-Granick test; acid; ALA; porphobilinogen; PBG; free erythrocyte protoporphyrin; fractionated erythrocyte porphyrins; FEP

What are they used for?

Porphyrin tests are used to diagnose or monitor porphyria.

Why do I need a porphyrin test?

You may need a porphyrin test if you have symptoms of porphyria. There are different symptoms for the different types of porphyria.

Symptoms of acute porphyria include:

Symptoms of cutaneous porphyria include:

You may also need a porphyrin test if someone in your family has porphyria. Most types of porphyria are inherited, meaning the condition is passed from parent to child.

What happens during porphyrin testing?

Porphyrins can be tested in blood, urine, or stool. The most common types of porphyrin tests are listed below.

  • Blood Test
    • A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
  • 24-Hour Urine Sample
    • You will collect all your urine during a 24-hour period. For this test, your health care provider or laboratory will give you a container and specific instructions on how to collect your samples at home. Be sure to follow all instructions carefully. This 24-hour urine sample test is used because the amounts of substances in urine, including porphyrin, can vary throughout the day. So collecting several samples in a day may give a more accurate picture of your urine content.
  • Random Urine Test
    • You can provide your sample at any time of day, with no special preparations or handling needed. This test is often done in a health care provider’s office or a lab.
  • Stool Test (also called protoporphyrin in stool)
    • You will collect a sample of your stool and place it in a special container. Your health care provider will give you instructions on how to prepare your sample and send it to a lab.

Will I need to do anything to prepare for the test?

You don’t need any special preparations for blood or urine tests.

For a stool test, you may be instructed to not eat meat or take any aspirin-containing medicines for three days prior to your test.

Are there any risks to porphyrin tests?

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

There are no known risks to urine or stool tests.

What do the results mean?

If high levels of porphyrin are found in your blood, urine, or stool, your health care provider will probably order more tests to confirm a diagnosis and to find out what kind of porphyria you have. While there is no cure for porphyria, the condition can be managed. Certain lifestyle changes and/or medicines can help prevent the symptoms and complications of the disease. Specific treatment depends on the type of porphyria you have. If you have questions about your results or about porphyria, talk to your health care provider.

Is there anything else I need to know about porphyrin tests?

While most types of porphyria are inherited, other types porphyria can also be acquired. Acquired porphyria can be caused by a variety of factors, including overexposure to lead, HIV, hepatitis C, excess iron intake, and/or heavy alcohol use.

Immunoglobulins Blood Test: MedlinePlus Lab Test Information

 

What is an immunoglobulins blood test?

This test measures the amount of immunoglobulins, also known as antibodies, in your blood. Antibodies are proteins made by the immune system to fight disease-causing substances, like viruses and bacteria. Your body makes different types of immunoglobulins to fight different types of these substances.

An immunoglobulins test usually measures three specific types of immunoglobulins. They are called igG, igM, and IgA. If your levels of igG, igM, or IgA are too low or too high, it may be a sign of a serious health problem.

Other names: quantitative immunoglobulins, total immunoglobulins, IgG, IgM, IgA testing

What is it used for?

An immunoglobulins blood test may be used to help diagnose a variety of conditions, including:

Why do I need an immunoglobulins blood test?

You may need this test if your health care provider thinks your immunoglobulin levels might be too low or too high.

Symptoms of levels that are too low include:

  • Frequent and/or unusual bacterial or viral infections
  • Chronic diarrhea
  • Sinus infections
  • Lung infections
  • Family history of immunodeficiency

If your immunoglobulin levels are too high, it may be a sign of an autoimmune disease, a chronic illness, an infection, or a type of cancer. Symptoms of these conditions vary greatly. Your health care provider may use information from your physical exam, medical history, and/or other tests to see if you are at risk for one of these diseases.

What happens during an immunoglobulins blood test?

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Will I need to do anything to prepare for the test?

You don’t need any special preparations for an immunoglobulins blood test.

Are there any risks to the test?

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

What do the results mean?

If your results show lower than normal levels of immunoglobulins, it may indicate:

If your results show higher than normal levels of immunoglobulins, it may indicate:

If your results are not normal, it doesn’t necessarily mean you have a medical condition needing treatment. The use of certain medicines, alcohol, and recreational drugs can affect your results. If you have questions about your results, talk to your health care provider.

Is there anything else I need to know about an immunglobulins blood test?

Your health care provider may order other tests to help make a diagnosis. These tests might include urinalysis, other blood tests, or a procedure called a spinal tap. During a spinal tap, a health care provider will use a special needle to remove a sample of a clear liquid, called cerebrospinal fluid, from your back.

Testosterone Levels Test: MedlinePlus Lab Test Information

 

What is a testosterone levels test?

Testosterone is the main sex hormone in males. During a boy’s puberty, testosterone causes the growth of body hair, muscle development, and deepening of the voice. In adult men, it controls sex drive, maintains muscle mass, and helps make sperm. Women also have testosterone in their bodies, but in much smaller amounts.

This test measures the levels of testosterone in your blood. Most of the testosterone in the blood is attached to proteins. Testosterone that is not attached to a protein is called free testosterone. There are two main types of testosterone tests:

  • Total testosterone, which measures both attached and free testosterone.
  • Free testosterone, which measures just free testosterone. Free testosterone can give more information about certain medical conditions.

Testosterone levels that are too low (low T) or too high (high T) can cause health problems in both men and women.

Other names: serum testosterone, total testosterone, free testosterone, bioavailable testosterone

What is it used for?

A testosterone levels test may be used to diagnose several conditions, including:

Why do I need a testosterone levels test?

You may need this test if you have symptoms of abnormal testosterone levels. For adult men, it’s mostly ordered if there are symptoms of low T levels. For women, it’s mostly ordered if there are symptoms of high T levels.

Symptoms of low T levels in men include:

  • Low sex drive
  • Difficulty getting an erection
  • Development of breast tissue
  • Fertility problems
  • Hair loss
  • Weak bones
  • Loss of muscle mass

Symptoms of high T levels in women include:

  • Excess body and facial hair growth
  • Deepening of voice
  • Menstrual irregularities
  • Acne
  • Weight gain

Boys may also need a testosterone levels test. In boys, delayed puberty can be a symptom of low T , while early puberty may be a symptom of high T.

What happens during a testosterone levels test?

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Will I need to do anything to prepare for the test?

You don’t need any special preparations for a testosterone levels test.

Are there any risks to the test?

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

What do the results mean?

Results mean different things depending on whether you are a man, woman, or boy.

For men:

  • High T levels may mean a tumor in the testicles or adrenal glands. Adrenal glands are located above the kidneys and help control heart rate, blood pressure, and other bodily functions.
  • Low T levels may mean a genetic or chronic disease, or a problem with the pituitary gland. The pituitary gland is a small organ in the brain that controls many functions, including growth and fertility.

For women:

For boys:

  • High T levels may mean cancer in the testicles or adrenal glands.
  • Low T levels in boys may mean there is some other problem with the testicles, including an injury.

If your results are not normal, it doesn’t necessarily mean you have a medical condition needing treatment. Certain medicines, as well as alcoholism, can affect your results. If you have questions about your results, talk to your health care provider.

Is there anything else I need to know about a testosterone levels test?

Men who are diagnosed with low T levels may benefit from testosterone supplements, as prescribed by their health care provider. Testosterone supplements are not recommended for men with normal T levels. There is no proof they provide any benefits, and in fact they may be harmful to healthy men.

When Do You Need an Antibiotic?

Do you know when an antibiotic is needed and when it’s not? Antibiotics are incredible life-saving drugs. They’re great for bacterial infections, like strep throat and many ear infections. But they aren’t cure-all wonder pills, and sometimes they can cause more harm than good. In this video, Dr. Michael Smith explains how antibiotics work and why you shouldn’t take an antibiotic “just to be safe.”

Semen Analysis: MedlinePlus Lab Test Information

 

What is a semen analysis?

A semen analysis, also called a sperm count, measures the quantity and quality of a man’s semen and sperm. Semen is the thick, white fluid released from the penis during a man’s sexual climax (orgasm). This release is called ejaculation. Semen contains sperm, the cells in a man that carry genetic material. When a sperm cell unites with an egg from a woman, it forms an embryo (the first stage of an unborn baby’s development).

A low sperm count or abnormal sperm shape or movement can make it difficult for a man to make a woman pregnant. The inability to conceive a baby is called infertility. Infertility can affect men and women. For about one-third of couples unable to have children, male infertility is the reason. A semen analysis can help figure out the cause of male infertility.

Other names: sperm count, sperm analysis, semen testing, male fertility test

What is it used for?

A semen analysis is used to find out if a problem with semen or sperm may be causing a man’s infertility. The test may also be used to see if a vasectomy has been successful. A vasectomy is a surgical procedure that is used to prevent pregnancy by blocking the release of sperm during sex.

Why do I need a semen analysis?

You may need a semen analysis if you and your partner have been trying to have a baby for at least 12 months without success.

If you’ve recently had a vasectomy, you may need this test to make sure the procedure has worked.

What happens during a semen analysis?

You will need to provide a semen sample. The most common way to provide your sample is to go to a private area in your health care provider’s office and masturbate into a sterile container. You should not use any lubricants. If masturbation is against your religious or other beliefs, you may be able to collect your sample during intercourse using a special type of condom. Talk to your health care provider if you have questions or concerns about providing your sample.

You will need to provide two or more additional samples within a week or two. That’s because sperm count and semen quality can vary from day to day.

Will I need to do anything to prepare for the test?

You will need to avoid sexual activity, including masturbation, for 2–5 days before the sample is collected. This will help make sure your sperm count is at its highest level.

Are there any risks to the test?

There is no known risk to a semen analysis.

What do the results mean?

The results of a semen analysis include measurements of quantity and quality of semen and sperm. These include:

  • Volume: the amount of semen
  • Sperm count: the number of sperm per milliliter
  • Sperm movement, also known as motility
  • Sperm shape, also known as morphology
  • White blood cells, which may be a sign of an infection

If any of these results are not normal, it may mean there is problem with your fertility. But other factors, including the use of alcohol, tobacco, and some herbal medicines, can affect your results. If you have questions about your results or other concerns about your fertility, talk to your health care provider.

If your semen analysis was done to check the success of your vasectomy, your provider will look for the presence of any sperm. If no sperm is found, you and your partner should be able to stop using other forms of birth control. If sperm is found, you may need repeat testing until your sample is clear of sperm. In the meantime, you and your partner will have to take precautions in order to prevent pregnancy.

Is there anything else I need to know about a semen analysis?

Many male fertility problems can be treated. If your semen analysis results were not normal, your health care provider may order more tests to help figure out the best approach to treatment.
