FAQ
Q: What is the significance of blood typing in hematological studies?
A: Blood typing is significant in hematological studies as it helps identify an individual's blood group and compatibility for transfusions.
Q: What are the AB0 and Rh systems in blood typing?
A: The AB0 system classifies blood types based on the presence or absence of certain antigens on red blood cells, while the Rh system indicates the presence or absence of the Rh antigen.
Q: How do direct and indirect Coombs tests contribute to immunohematology?
A: Direct Coombs test detects antibodies attached to red blood cells, while the indirect Coombs test detects antibodies in the serum that may cause immune reactions.
Q: What is the significance of detecting irregular antibodies in immunohematology?
A: Detecting irregular antibodies is crucial in immunohematology to prevent adverse reactions during blood transfusions by ensuring compatibility between donor and recipient blood.
Q: What is antibody titration and how is it used in immunohematology?
A: Antibody titration is a semi-quantitative method that measures the strength of antibodies in the serum, helping in identifying antibodies in pregnant women and characterizing high-titer antibodies for effective treatment.
Q: How is the absorption technique utilized in identifying blood antigens?
A: The absorption technique is used to remove interfering antibodies from the serum, allowing accurate identification of specific blood antigens and resolving blood group discrepancies.
Q: What are the potential applications of molecular testing in immunohematology?
A: Molecular testing in immunohematology is valuable for feto-maternal evaluation, genetic diagnostics, and assisting in the identification of blood-related disorders or abnormalities.
