Markers of renal function tests

BACKGROUND The markers of renal function test assess the normal functioning of kidneys. These markers may be radioactive and non radioactive. They indicate the glomerular filtration rate, concentrating and diluting capacity of kidneys (tubular function). If there is an increase or decrease in the valves of these markers it indicates dysfunction of kidney. AIM The aim of this review is to compare and analyze the present and newer markers of renal function tests which help in diagnosis of clinical disorders. MATERIAL #ENTITYSTARTX00026; METHODS An extensive literature survey was done aiming to compare and compile renal function tests makers required in diagnosis of diseases. RESULTS Creatinine, urea, uric acid and electrolytes are makers for routine analysis whereas several studies have confirmed and consolidated the usefulness of markers such as cystatin C and β-Trace Protein. CONCLUSION We conclude that further investigation is necessary to define these biomarkers in terms of usefulness in assessing renal function.
