venous blood (though you draw from the aorta on a corpse), and plain serum (i.e., no anticoagulant).
?? you mean whole blood vs. serum? serum is the liquid sans cellular material, typically used in chemistry analysis. whole blood would be your anti-coag tubes, for hematology(cbc, pt/ptt, etc..)
you draw whole blood, but because you put it in a tube without coagulant it clots in there and gets to the lab with the serum on the top, ready for them to work on. this is why you do use plain tubes for chemistries, enzymes, drug levels-- anything that says, "serum....." in it (like "serum sodium").
when you put whole blood in a tube with anticoagulant (like purple or blue tops), that keeps it from clotting, so you can do things like look at hgb/hct, and cbc.
