It is important to separate the cellular and liquid portions of a blood specimen as soon as possible when the test requires a sample of serum or. plasma. This is because the cells interact with the serum/plasma, altering its chemical composition and affecting test results. Tau is a microtubule-associated protein in neurons and strongly associated with overall brain degeneration. A proper gel seal between the cells and the serum/plasma is needed to prevent leakage into sample. Get help now: Gently invert the tu bes 3-4 times immediately after sampling to avoid the formation of microclots.
