A Verified Doctor answered. Blood from a single donation or sample can be separated into different components: proteins, red blood cells, white blood cells, clotting factors, etc., and used for their individual purposes. Make sure that all tubes are legibly labeled, using a permanent marker/pen. After centrifugation, store the serum in a separate test tube and retain the red blood cells in the original tube. It is helpful to be able to recognize these differences because sometimes they can interfere with Chemistry tests.

This is the supernatant that is removed after a clot has formed and centrifugation of blood collected in a red top tube (see note #3 below about serum separator tubes). Other bodily components that contribute to plasma's yellow hue are carotenoids, which are pigments commonly found in fruits and vegetables like carrots, and haemoglobin, a protein found in red blood cells. The cells and clotting factors must be removed from the blood sample by allowing adequate time for a clot to form. The cells are removed by centrifugation. If it turned red colour, we could be explain the hemolysis will occur when animal test. Other than methaemoglobin, dark serum coloration can be caused by presence of myoglobin or methaemalbumin, which is composed of albumin bound to oxidized free heme due to intravascular haemolysis.Click to see full answer. but here is a suggested video that might help. Serum blood collection tubes promise to provide unpolluted and undifferentiated original blood samples for medical testing.After centrifugation, serum can be effectively separated from blood cells and fibrin.There are three types of serum tubes: plain tube with red cap, a red cap precoagulation tube, and a yellow cap coagulation gel activator tube.
