Which protein determines whether blood type is positive or negative?
1 If your parents are both negative, then you are Rh 2  (-). If your parents are both positive or if one of your parents is positive and the other is negative, you can get a blood test and look for the Rhesus factor to know if your blood type is (+) or (-).sk your doctor for a blood typing test. If your parents have different blood types, or their blood type is unknown, you can ask your doctor to perform a simple blood typing test to find out whether your blood is positive or negative. Every person has a blood type (O, A, B, or AB) and an Rh factor, either positive or negative. The blood type and the Rh factor simply mean that a person's blood has certain specific characteristics.The blood type is found as proteins on red blood cells and in body fluids.The Rh factor is a protein that is found on the covering of the red blood cells. If the Rh factor protein is present on the cells, the person is Rh positive. If there is no Rh factor protein, the person is Rh negative. baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh positive gene is dominant (stronger), and even when paired with an Rh negative gene, the positive gene takes over. There are two major ways of distinguishing between blood types. The first is the ABO blood system, where the blood type is defined as either A, B, AB or O. The second is the Rhesus (Rh) blood group system, which determines whether a blood type is negative or positive.sk your doctor for a blood typing test. If your parents have different blood types, or their blood type is unknown, you can ask your doctor to perform a simple blood typing test to find out whether your blood is positive or negative. Find out your parents' blood type. Sometimes it's possible to determine whether you have a positive or negative blood type simply by finding out your parents blood type. However, this only works if both of your biological parents have the same Rhesus factor.sk your doctor for a blood typing test. If your parents have different blood types, or their blood type is unknown, you can ask your doctor to perform a simple blood typing test to find out whether your blood is positive or negative. A, B, AB, and O are the four main categories of blood. Each of these blood types is further classified as negative or positive, which is a reference to the blood's Rhesus factor. People who have the antigen in their blood, or Rh factor, are deemed Rh-positive.For example, a person with the A blood type and Rhesus factor in their blood has A-positive blood.It is estimated that more than 85 percent of people throughout the world are Rh-positive. People who do not have the antigen, or are without the Rhesus factor, are Rh-negative.For example, a person with the O blood type and no Rhesus factor in their blood has O-negative blood. Whether or not a person is Rh positive or Rh negative is really only significant with respect to pregnancies., B, AB, and O are the four main categories of blood. Each of these blood types is further classified as negative or positive, which is a reference to the blood's Rhesus factor. People who have the antigen in their blood, or Rh factor, are deemed Rh-positive. The results of blood typing will determine if a person is type A, B, AB, or O and if he or she is Rh negative or positive. The results will tell the healthcare provider what blood or blood components will be safe for the person to receive.he Test. Blood typing is used to determine an individual's blood group, to establish whether a person is blood group A, B, AB, or O and whether he or she is Rh positive or Rh negative. The Test.

If a blood type does not have Rh protein, then it is negative. - For example, blood type B negative means that the person has type B without Rh protein on the surface of the red blood cells. The RH factor is more important if the mother is to have a second child. 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's father is Rh positive.h positive is the most common blood type.
