Abstract

Chronic kidney disease (CKD) is an important public health problem and is a risk factor for cardiovascular diseases. CKD is usually asymptomatic until later stages and routine laboratory tests, including serum creatinine and urine protein, are not clinically sensitive enough to detect early stages of CKD. Using creatinine clearance is a suitable approach for detecting early stages, but it has different challenges. In addition, the clinical usefulness of these laboratory tests results is affected by analytical sensitivity and specificity, biological variation, need to collect 24 hours urine, diet, and activity. As early detection of CKD is necessary for preventing the progression of kidney disease to kidney failure, it is essential to standardize these laboratory tests in pre-analytical, analytical, and post-analytical stages, and using more sensitive and specific tests. For more than ten years, it is recommended to use estimated glomerular filtration rate (eGFR) as a sensitive marker for screening early stages of CKD. Different formulas have been introduced for estimation of GFR according to serum creatinine, race, sex, age, and body weight, each of which has its advantages and disadvantages.
In this panel, we will discuss about challenges in detection, diagnosis and monitoring of CKD in pediatrics and adults according to laboratory tests, problems of standardization of creatinine and urine albumin measuring methods, and limitations of different formulas for estimating GFR, and also introduce strategies for quality improving of these tests.
