MODULE 1 Flashcards
Clinical comes from a greek word “kline” which means?
bed
Is the science which deals with the elements, their compounds and the chemical structures and interactions of
matter
Chemistry

newborn
erythroblastosis fetalis
Medical technologist have control over in vivo hemolysis. T/F
