![]() Unless there was a mistake in the testing process, the result is conclusive evidence of either parentage or non- parentage.Īnother difference between determining paternity by DNA and determining paternity by blood type chart, is the fact that for the blood type chart to be used, information on the blood groups of either one or both of the supposed parents must be available. The DNA test result is on the other hand very reliable. It can only be used to disprove parentage and not to prove that an individual is the father of the child. Perhaps the greatest difference between these two paternity tests is that the blood type chart cannot be used as conclusive proof of fatherhood. A blood type chart provides information on the expected blood types of children from that of their parents. For example, parents with an O blood group can only have children with an O blood group too (either O negative or O positive). Blood types are also inherited from parents and this is the principle under which a blood type chart works. Simply put, it is a chart that gives details of the expected blood group of a child’s blood, in relation to the blood type of his or her parents. It is more theoretical than practical in its approach to establishing parentage. On the other hand, determining paternity by blood type chart is not really a test per se. If the alleged father is not the real father, there will be not be enough shared genetic material. This is because DNA is the material that is inherited by children from their parents. In the event that the man is the biological father of the child, the test will usually give a 99.9% probability. The two samples are compared to see if the alleged father and child share the same genetic markers. The samples must then be sent to the lab for testing – obviously both the father and the child need to provide samples. When determining paternity by DNA, samples of the child’s DNA are taken in order to derive a genetic profile usually samples are collected using oral swabs. A man can opt for any one of these two tests although the most accurate results can only be provided with a DNA test. The most common of these is the DNA test or a more out-dated, almost totally disused way, is by using a blood type or blood- typing, as it is commonly referred to.

If you mix blood from two people with wrong blood types, the antibodies in the blood of the person receiving the transfusion will fight the cells of the donor’s blood, resulting in a potentially fatal toxic reaction.Ībove and beyond ABO blood typing, your blood will be classified by the presence or absence of a specific protein (rhesus factor): If you have type B blood, you can receive type B or type O blood.If you have type A blood, you can receive type A or type O blood.If you have type O blood, you are a universal donor and can donate blood to anyone.If you have type AB blood, you are a universal recipient and can receive blood from all donors.The system is based on antigens that are either present or absent on the surface of a person’s red blood cells.īecause of compatibility issues between blood groups, it’s critical that appropriate donors are matched with a person who needs a blood transfusion: ![]() The ABO blood group system groups human blood into four main types: The ABO blood type system and how it affects donating or receiving blood
