Your blood type tells you about markers on the surface of your red blood cells. The red blood cells also have a protein that is called Rh on the surface of the cell. Your blood can be Rh positive, which means that you have the Rh protein, or Rh negative, which means that you do not have the Rh protein. The letter of your blood group plus the Rh makes your blood type.

A test that tells you your blood type is done at your first prenatal visit and usually when you are admitted to the hospital for labor if you are planning a hospital birth. If you ever need a blood transfusion, you should be given blood that is your same blood type. You can become very sick if you are given blood that is a different blood type unless it is O blood, which will not cause harm to people who have other blood types. Being Rh negative means that you do not have Rh proteins on your red blood cells.

This is why being Rh negative will not harm your baby during your first pregnancy. But in your next pregnancy, the antibodies that you made when you were exposed to Rh-positive blood at your first birth can cross the placenta and attack the Rh-positive red blood cells, if your next baby has Rh-positive blood. This is called Rh sensitization. Rh sensitization can cause fetal anemia low iron in the blood , miscarriage, stillbirth, or a serious illness in the baby that is called hemolytic disease of the newborn.

Fortunately, Rh sensitization is very rare because women who are Rh negative can get a shot that stops their body from making antibodies to Rh-positive blood.

It is found in all rhesus monkeys, thus the name Rh. Most people have it too, but some do not. If either parent is Rh positive, the baby may be Rh positive or negative. If both parents are Rh negative, the baby will also be Rh negative. All pregnant women will be tested for Rh status during routine bloodwork taken early in pregnancy. This testing is becoming more and more common.

Problems can arise if the mother is Rh-negative, and the baby is Rh-positive. Because the mother does not have this particular protein in her body, her immune system will perceive it as a foreign and possibly harmful substance. In most cases, this sensitization will not happen until delivery, in a first pregnancy. It is the subsequent pregnancies that are of concern.

The most common type is Rh positive. Being Rh positive or negative typically does not affect your health, but it could affect your pregnancy. At your first prenatal visit, your doctor will suggest a blood type and Rh factor screening. If you are Rh-, your doctor will test your blood again later in your pregnancy to see if you have formed antibodies against Rh factor.

If your doctor identifies a potential for Rh incompatibility , your pregnancy will be monitored closely for any related issues and may need extra care. If this occurs, your baby might need a red blood cell transfusion either during your pregnancy or immediately after delivery. Compatible blood types could be useful if you or your partner need a blood transfusion.

Rhesus disease occurs during pregnancy when there is an incompatibility between the blood types of the mother and baby. These blood types are further identified as being either positive or negative.

The idea that personality traits were inherited through the blood dates as far back as Aristotle. It was seen to be a non-statistical and unscientific report motivated by racism.

The study did find, however, that symptomatic individuals with blood types B and AB who were Rh positive were more likely to test positive for COVID, while those with blood type O were less likely to test positive. The rise of COVID in all corners of the world sent scientists scrambling to find characteristics that might render individuals more susceptible to the virus, as well as risk factors that might intensify its severity and progression. This has resulted in numerous theories and reports about the association between COVID and blood type, which have often led to more questions than answers.

The large retrospective review showed no significant connection between blood type and worsening of the disease, between blood type and the need for hospitalization, positioning requirements for patients during intubation, or any inflammatory markers. An intriguing finding from the study was that there appeared to be a greater chance of people with blood types B and AB who were Rh positive testing positive for the virus. Even stronger evidence was assembled by the team that symptomatic people with blood type O were less likely to test positive.

For now, though, the researchers are confident that their principle finding—that ABO blood typing should not be considered prognostic in patients who acquire COVID—will help debunk the kinds of clinically unfounded rumors and misinformation that can readily gain traction in the midst of a pandemic, and in some cases become part of accepted medical practice.

Rh incompatibility is when a mom is Rh negative and her baby is Rh positive, which can cause problems during pregnancy.

A short biology lesson can help explain why. Each cell in the body has numerous antenna-like structures, known as antigens, on its surface.
