Abstract:

Uric acid,creatinine,urea and cystatin C(Cys C) are the most commonly used serum renal function items. However,due to the influence of pre-analysis factors,including physiological factors,sample appearance and drugs,the determination results may not be consistent with the clinical manifestations of patients,or even the false results may affect clinical judgement,resulting in misdiagnosis and wrong intervention,and increasing the risk of patients. Clinicians,nurses and laboratorians should pay attention to the above pre-analysis factors,be aware of the influence,and timely find the wrong results caused by the interference of the pre-analysis factors on the determination methods,so as to correctly guide sample collection,and interpret and communicate the results with doctors and patients. This review focuses on the pre-analysis factors affecting the determination of 4 serum renal function items.
