Any other names for this test?
This test is also known as Rh incompatibility or the Rh factor.
What exactly is Rh type?
The Rhesus factor, often known as the "Rh factor," is a type of protein present on the surface of red blood cells. Rh-positive means individuals have the protein, whereas Rh-negative means individuals do not have the protein.
Rh positive or Rh negative is indicated by the "+" or "-" that you might notice after your blood type.
What is an Rh-type lab test?
The Rh-type test
determines if you have the Rh factor present on the outer layer of your red blood cells. This Rh protein is passed down to you from your genetic parents. Taking a rhodopsin test during pregnancy is important because if you are Rh negative and your baby is Rh positive, you may develop rhodopsin incompatibility.
The test results show if you are Rh positive or Rh negative. If you are Rh-positive, you have Rh protein in your blood. And if you are negative, you do not have Rh protein in your blood.
The most common Rh type is positive, which means, However, Rh negativity is not very common.
Why do I need an Rh-type test?
This test is often administered to pregnant women at their initial prenatal visit. You could take this test if you:
What is Rh incompatibility?
- Are Expecting
- You are considering becoming pregnant
- You are the biological father's unborn child
- You are Rh-negative and expecting a child with a Rh-positive partner
- Require a blood transfusion
- You are interested in donating blood
Rh incompatibility occurs during pregnancy, necessitating the use of an Rh-type test
. This condition refers to Rh factor problems. For instance, if you are Rh negative and your unborn child is Rh positive, it means you may have Rh incompatibility. Some of your baby's blood may travel through the placenta into your body during pregnancy. Your body might produce antibodies against the baby's blood in an attempt to defend itself from it. It might cause:
What complications are related to Rh incompatibility?
- Ectopic pregnancy
- Vaginal bleeding
- Chorionic villus sampling (CVS)
- menstrual extraction
Pregnancy has no impact on Rh incompatibility. Hemolytic anemia can develop in a fetus as a result. Hemolytic anemia causes the fetus's red blood cells to be destroyed faster than they can be replaced.
Rh incompatibility can have mild to severe side effects. These impacts may also include,
- liver disease
- A heart attack
The fetus may not require treatment if the side effects are minor. If the Rh condition is minor, most fetuses recover completely.
If the problem is dangerous, the fetus might require a blood transfusion. This procedure results in the replacement of red blood cells. Medical personnel might use specialized lights to help reduce bilirubin levels in a fetus with jaundice. To avoid serious anemia problems, you might need to deliver the baby early.
Since the development of Rh immune globulin injections, Rh disease has been less common. In case you want to determine whether you are Rh incompatible. Schedule an R-type test
How do I prepare for an Rh-type test?
You do not need to prepare anything special for an Rh-type test.
However, you should let your healthcare provider know about any medicines or supplements you are taking. Because factors can affect the testing results.
How does an Rh-type test perform?
The test requires a blood sample. Your medical professional will carry out the following
How long does an Rh-type test take?
- Your medical expert will first clean the puncture site with an antibiotic.
- He will next put an elastic band over the upper area of the hand to draw blood into the vein.
- He is now going to inject a little needle into the vein.
- Blood collected from the needle will be placed in a test container for testing.
- The blood test is now complete.
- The process of drawing blood has now been completed. Your medical team member will remove the elastic band.
A blood test does not take too long. The testing only takes five minutes to get done. However, your healthcare provider might take a few seconds to find the vein in your hand.

This testing poses no harmful risks. However, you may feel a little pain and bruise around the spot where the needle went. These signs will go away in the next two or three days.
What do the test results mean?
If you are pregnant and your test results are Rh-positive, there is no need to worry about it. Your body might produce antibodies that could be dangerous if you are Rh-negative and your child is Rh-positive. Follow these instructions:
What other test needs to be done besides the Rh-type test?
- Contact your healthcare provider right away if you experience vaginal bleeding at any point during your pregnancy.
- Consult your doctor about arranging an RH-immune globulin injection during your pregnancy.
- Remind your medical staff that you are Rh-negative when you are in labor.
A blood test known as an "antibody screen" may be required if an Rh-type test
reveals that you are Rh-negative. The antibody screen scans your blood for antibodies. If antibodies are found, it indicates that you have come into contact with Rh-positive blood and have grown immune to it. Throughout your pregnancy, you might require several antibody screenings, as well as one right before birth.
If the baby's father cannot or will not undergo the Rh blood test, you might additionally require an amniocentesis. A needle is inserted into the uterus during amniocentesis to extract a small amount of amniotic fluid for testing.
