Blood tests. • Estimated Glomerular Filtration Rate (eGFR) - The best measure of your kidney function. It shows how well your kidneys are cleaning the blood. Your eGFR is usually estimated from the results of the creatinine blood test. eGFR is reported in millilitres per minute per 1.73m2(mL/min/1.73m2). An eGFR of 100
Kidney Function Test. BIOCHEMISTRY. MODULE. Biochemistry. Notes. 16. KIDNEY FUNCTION TEST. 16.1 INTRODUCTION. The main function of the kidney is excretion of water soluble waste products from our body. The kidney has various filtration, excretion and secretary functions. Derangement of any of these function
end-stage renal disease (ESRD). Quantitation of urine protein excretion, such as the measurement of a spot urine albumin-to-creatinine ratio, is critical for determining the severity of CKD and monitoring the rate of disease progression. The glomerular filtration rate (GFR) is the single best indicator of kidney function.
is produced in the liver. From there, it travels through the blood and is excreted by the kidneys.Urea is filtered at glomerulus, where the tubules reabsorbed approximately 40%. Thus under normal conditions, urea clearance is about 60% of the true GFR
PREOPERATIVE RENAL FUNCTION TESTS. Rachel Perez, MD (2003-2004). Creatinine value. Creatinine is the end-product of skeletal muscle catabolism. Creatinine is disposed almost entirely by glumerular filtration. Normal ranges of serum creatinine are 0.5 to 1.5 mg/dl. Creatinine production is proportional to skeletal
Renal function tests are of limited value in differential diagnosis, except to establish the existence of uremia. The ability of the kidney to concentrate urine is often the first function to manifest impairment, but is of little value in prognosis. All clearance tests suffer a similar disability: Hypertrophy of nephrons with resto- ration of

Kidney Disease: Kidney Function Tests. How well your kidneys work is called kidney function. Chronic kidney disease may not cause symptoms until your kidney function has dropped to a very low level. Testing is vital to help your doctor know: • Whether kidney disease has developed suddenly or as a long-term process.
Upon completion of this course, one should be able to: • Describe the anatomy of the kidney and nephron. • Explain the function of the kidneys and production of urine. • Recognize reference values for renal function tests. • Describe characteristics of common at least 4 renal diseases requiring renal function tests. • Discuss
