ABO Blood Group System - Exam 1 Questions and Answers Graded A What are the five blood types? A, B, AB, O, ? What are the genotypes for the four major ABO blood groups? A: AA, AO B: BB, AO AB: AB O: OO Describe forward typing. Patient blood of an unknown type is mixed with known sera. A positive result is agglutination. An example: If anti-A serum causes a positive reaction, and the anti-B serum has a negative reaction, then the cells only have the A antigen and the blood type is type A. Desc...

What is a DAT, and when would it be used? correct answers Also called the Coombs test, the Direct antiglobulin test is able to detect IgG bound RBC's in vivo. This test is used in cases of AIHA, HDFN, transfused cells to detect IgG coated cells What is the principal of the DAT?(how is it performed) correct answers A blood sample is obtained from a patient. A red cell suspension is created and washed. The coombs reagent is then added and examined macroscopically and microscopically for agglut...
