Question

what is Rh-factor.....

Answer 1

The Rh-factor is named after the rhesus monkey .

The Rh-factor is a type of human blood group systems.

Explanation :

When the blood of a Rh-positive person is transfused to Rh-negative , then the antibody causes a reaction and this may even lead to the death of the person.

This is almost like allergy.

When an Rh negative woman becomes positive due to carrying a Rh-positive child , then this may lead to abortion during conceiving the second child.

The first Rh-positive child will be normal.

But if it sensitisizes the mother , this will lead to problem.

Answer 2

Hi

Here is the answer

Rhesus (Rh) factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you're Rh positive. If your blood lacks the protein, you're Rh negative.

Rh positive is the most common blood type. Having an Rh negative blood type is not an illness and usually does not affect your health. However, it can affect your pregnancy. Your pregnancy needs special care if you're Rh negative and your baby is Rh positive (Rh incompatibility). A baby can inherit the Rh factor from either parent.During pregnancy, problems can occur if you're Rh negative and the baby you're carrying is Rh positive. Usually, your blood doesn't mix with your baby's blood during pregnancy. However, a small amount of your baby's blood could come in contact with your blood during delivery or if you experience bleeding or abdominal trauma during pregnancy. If you're Rh negative and your baby is Rh positive, your body might produce proteins called Rh antibodies after exposure to the baby's red blood cells.

The antibodies produced aren't a problem during the first pregnancy. The concern is with your next pregnancy. If your next baby is Rh positive, these Rh antibodies can cross the placenta and damage the baby's red blood cells. This could lead to life-threatening anemia, a condition in which red blood cells are destroyed faster than the baby's body can replace them. Red blood cells are needed to carry oxygen throughout the body.

If you're Rh negative, you might need to have another blood test — an antibody screen — during your first trimester, during week 28 of pregnancy and at delivery. The antibody screen is used to detect antibodies to Rh positive blood. If you haven't started to produce Rh antibodies, you'll likely need an injection of a blood product called Rh immune globulin. The immune globulin prevents your body from producing Rh antibodies during your pregnancy.

If your baby is born Rh negative, no additional treatment is needed. If your baby is born Rh positive, you'll need another injection shortly after delivery.
