2nd post- blood samples using serum vs plasma


Mill's first 2 blood tests sent to Cornell were serum. The last was plasma and all of the levels were considerably elevated. My vet tech friend comes out to draw her blood and we spin it down 2 minutes later in my kitchen. The samples are sent by express mail on ice. Should it make a difference in the numbers whether we use plasma or serum if the lab allows either type? We were checking ACTH, Insulin, Glucose & Leptin.
