Question
Blood Typing Objective Learn about the mechanism of the ABO and Rh blood typing system in humans by performing a blood typing test using Eldon card . . Learn about Standard Precautions. Background Standard Precautions: Before participating in this lab, review the Standard Precautions (aka. Universal precautions) that have been provided by your instructor. Blood and other body fluids can carry infectious diseases that are potentially life threatening. When performing this lab activity, you will be required to use the ollowing standard precautions: Wear gloves when handling another person's blood or other body fluid Avoid skin or glove punctures with sharp objects such as needles or lancets by handling these objects carefully. . . Dispose of sharps in the designated sharps container. Do not dispose of sharp objects in the trash. Cotton balls, alcohol wipes and other"dry' waste (ie. no liquid leakage) may be thrown away in the trash. Wash your hands thoroughly after you remove your gloves ABO blood types: Human red blood cells express membrane glycoproteins that have antigenic properties. These proteins, designated A, B and O are the basis of the human ABO blood type system and are determined genetically. An individual may be a type A, type B, type AB or type O.The inheritance pattern is a combination of co-dominance (A and B antigens) and simple dominance (O antigen; designated as T" for the dominant allele and T for the recessive allele). Since we get one blood type gene from each parent, we each have two of the three possible alleles. By recombining the alleles, four blood types (genotypes) are possible. Complete Table 20-1 .

Based on this ABO and Rh system, blood groups are classified into 8 different types – A+ve, A-ve, B+ve, B-ve, AB+ve, AB-ve,O+ve,O-ve blood group systems. Of these 8 blood groups, AB+ve blood group persons are considered as universal recipients as these people can accept blood from all other blood group people. This blood group person expresses both antigen A, and antigen B on their RBC and they also express the Rh factor. They do not produce any anti-A, anti-B, or anti-Rh antibodies and that is the reason why they can receive blood from all types of blood group persons. On the other hand O-ve people are considered as universal donors as they do not express antigen A, antigen B, or antigen Rh on their RBC surface. So, they can donate their blood to any other type of blood group person.
