Chronic kidney disease (CKD) is a worldwide problem and its incidence is steadily increasing. Kidney Disease Outcomes Quality Initiative (K/DOQI) of the National Kidney Foundation (NKF) defines chronic kidney disease as either kidney damage or a decreased kidney glomerular filtration rate (GFR) of less than 60 mL/min/1.73 m2 for 3 or more months (Levey AS.,2011). Whatever the underlying etiology, the destruction of renal mass with irreversible sclerosis and loss of nephrons leads to a progressive decline in GFR. CKD progression is associated with high morbidity and mortality (Sanz AB.,2014) .The early detection of CKD is important and early treatment may reduce adverse outcomes associated with CKD and slow or even prevent the progression of the disease. Therefore, the detection of CKD at early stages is an important public health issue (Katherine T.,2015).
