ACTH, Insulin & glucose testing-serum vs plasma


Is there any advantage to one compared to the other? Mill's first two samples were serum and the results seemed okay. The latest test was plasma and are the highest yet. My vet tech friend comes out to draw the blood and we spin it down in my kitchen about 2 minutes later. It doesn't get much fresher than that. All three samples were shipped the same way, express mail on ice.
