The indirect Coombs' test (anti-immunoglobulin test) typically uses:

A) Patient's red cells to determine whether they will bind IgG
B) patient's red cells to determine whether they will bind all immunoglobulins
C) patient's serum to determine whether it forms a precipitate with donor plasma
D) patient's serum to determine whether it contains antibodies that bind to a variety of reagent red cells
E) patient's serum to determine whether it contains antibodies that bind to the patient's red cells

As the fast, light reader, might choose E or if lucky on that day will choose D since come 1st or have vague memory of word react or rea..gent.

Guess, it is true some friends' friends read Q bank 4 to 6 times but others 3 to 4 times. I am not the patient repeat reader or reciting/ memorizing for no reason or understanding in deep/ well/ detailsad I think I have to change the way I studyconfusedcoolnod

GL to all of usnodnodgrin
