Don't be afraid of the AFP test during pregnancy! Let's learn the details (Alpha-Fetoprotein Test)

If you are a mother-to-be, your doctor may have asked you to have an 'AFP test'. When you hear this name, you may feel a little scared and nervous. Things like, "What is this? Why is this being done? Is there something wrong with the baby?" may come to your mind. But don't be scared at all. This is a common and important test that is often performed on pregnant mothers. It is used to get a small clue about the health of the baby. So, today we will find answers to all the questions you have in mind about this AFP test.

What is an AFP test simply?

Simply put, the Alpha-Fetoprotein (AFP) test is a blood test that checks the levels of a protein called AFP in your blood.

Now you're probably thinking, "What is this AFP protein?" It's very simple. It's a protein that's produced by the liver of your little baby in your womb. As your baby grows, some of this protein gets into the amniotic fluid around your baby, and from there it enters your bloodstream. So, by taking a little of your blood and testing it, you can measure how much of this AFP protein you have.

Normally, AFP levels should be within a certain range during pregnancy. If the level is too low or too high , it can give doctors a small clue that the baby in the womb may have a genetic condition or birth defect.

Can an AFP test be done on someone who is not pregnant?

Yes, this may sound a bit strange, but doctors sometimes ask non-pregnant people to do an AFP test. But the purpose of this is completely different.

AFP levels are normally very low in a non-pregnant adult or child (except for a newborn baby). If this level is elevated for no apparent reason , it can be a sign of some medical condition. Therefore, this test is used to help diagnose diseases such as cancer. It is called the AFP tumor marker test .

Conditions that may be indicated by elevated AFP levels:

• Liver cancer
• Ovarian cancer or testicular cancer
• Cirrhosis of the liver
• Inflammatory conditions of the liver, such as hepatitis A, B or C

Also, when treating a cancer patient, doctors sometimes use this AFP test to see if the treatment is successful. If the AFP level decreases with treatment, it means that the treatment is successful.

When is the AFP test done during pregnancy? Who is it especially important for?

This AFP test is usually performed on a pregnant mother between 16 and 22 weeks of pregnancy . This is considered the best time to get accurate results.

Actually, every pregnant woman can have this test. But your doctor may recommend this test especially if you have any of the following risk factors:

• If you are over 35 years old.
• If someone in your family has had a child with a birth defect .
• If you have diabetes (Diabetes Mellitus) .

In cases like this, the risk of the baby developing some complications is relatively high, so it is very important to have this test done.

What are these tests looking for?

The AFP test is like a detective. It reveals several important clues about the baby's health. Let's take a look at what they are.

How is the test done and what do I need to prepare for it?

You don't need to worry about this at all. The AFP test is a very simple, routine blood test.

To be precise, at the lab, a nurse or doctor will take a small amount of blood from a vein in your arm . It takes less than five minutes. Some people may have a slight fear of needles. If you have a similar fear (trypanophobia), tell the person taking the blood beforehand. You can do something during this time, such as taking deep breaths and looking away.

There is no special preparation required for this test. However, it is a good idea to drink plenty of water before the test. This will make it easier to find your vein and the blood draw will be quicker.

How to understand the results of the AFP test?

This is the most important part. When you get your AFP test report, don't be alarmed by the numbers. Your doctor is there to help you understand it.

This is only a screening test. That is, it only checks to see if there is a risk. If it shows that there is a risk, further tests will be needed to confirm it.

Let's see what the unusual results can hint at.

As you can see, an abnormal result doesn't necessarily mean a problem for the baby. So the best thing to do is not to panic and talk to your doctor as soon as you see the report.

If the AFP report is extraordinary, what happens next?

If your AFP result is outside the normal range, your doctor will first reassure you. Then, they may recommend a few more tests to confirm the result or find the exact cause.

• Other blood tests: Sometimes, along with the AFP test, other hormone tests, such as the triple screen test, are also done. These can provide further information.
• Detailed Ultrasound Scan: Your doctor will refer you to a specialist for a detailed scan. This will examine your baby's spine, brain, and other organs to look for any abnormalities.
• Definitive diagnostic tests: If you are still in doubt after the above tests, your doctor may suggest a test such as amniocentesis or chorionic villus sampling (CVS) . These take a sample of the baby's cells and test them, so you can be 100% certain whether or not there is a genetic condition.

What else do you want to ask the doctor?

Talk openly with your doctor about this. Don't hesitate to ask any questions or concerns you have. For example:

• "Doctor, when is the best time for me to get this AFP test?"
• "What exactly does the value in my AFP report say?"
• "Do I need to do any further tests based on this report?"
• "What steps should we take next?"

Your doctor will explain everything to you and give you the guidance you need.
