Background: Though serum has traditionally been the main type of sample for biochemical tests, some laboratories are increasingly using plasma now due to factors such as inadvertent clogging of auto-analyzer probes by fibrin clot in serum and delay in sample testing due to time required for blood clotting. Many previous studies on stability of biochemical analytes have mainly focused on serum with limited works on plasma.
Aim: We studied the stability of commonly used clinical biochemical analytes in human plasma including the comparative effects of storage time (0, 7, 14, 21 days) and temperature (room temperature, 4°C-8°C refrigeration temperature and -60°C) on blood separated plasma.
Methodology: Plasma samples were obtained from 6 healthy adults who are not on any medication. Urea, creatinine, sodium, pot.. View More»
