Very helpful video. I have a question though. In the case of plasma, the layers of the different blood cells (rbc,wbc, plat) and the plasma is created from the process of centrifuging the sample? Also, since plasma and serum is essentially the same thing (with the only difference being the absence of coagulant factors in serum) while on the same time, serum is more time consuming to make, why do they use serum in diagnostic techniques and not plasma?
Because we will have to neutralize the coagulatants using anticoagulants if we use plasma. And that will interfere with the tests. So you can think of serum like a more purified form for testing biochemicals.
So in the serum sample the serum lacks the fibrinogen because it was used to clot the blood correct where as in the plasma its still present because the coagulant and centrifuged separated it and so the fibrinogen wasn't used to clot the blood?
TNF-α is an important pro-inflammatory cytokine that both directly activates neutrophils and primes the cells for subsequent stimulation including phagocytosis
