LABORATORY TESTS TO EVALUATE TUBULAR FUNCTION

Tests to Assess Proximal Tubular Function Renal tubules efficiently reabsorb 99% of the glomerular filtrate to conserve the essential substances like glucose, amino acids, and water. 1. Glycosuria In renal glycosuria, glucose is excreted in urine, while blood glucose level is normal. This is because of a specific tubular lesion…

MICROALBUMINURIA AND ALBUMINURIA

Normally, a very small amount of albumin is excreted in urine. The earliest evidence of glomerular damage in diabetes mellitus is occurrence of microalbuminuria (albuminuria in the range of 30 to 300 mg/24 hours). An albuminuria > 300-mg/24 hour is termed clinical or overt and indicates significant glomerular damage. (See…

BIOCHEMICAL TESTS USED TO ASSESS RENAL FUNCTION

Two biochemical parameters are commonly used to assess renal function: blood urea nitrogen (BUN) and serum creatinine. Although convenient, they are insensitive markers of glomerular function.   Blood Urea Nitrogen (BUN)   Urea is produced in the liver from amino acids (ingested or tissue-derived). Amino acids are utilized to produce…

Estimation of Creatinine Clearance from Serum Creatinine by Prediction Equations

One can estimate GFR from age, sex, body weight, and serum creatinine value of a person from the following formula (Cockcroft and Gault):     Creatinine clearance in ml/min = (140 - Age in years) × (Body weight in kg)                     …

CLEARANCE TESTS TO MEASURE GLOMERULAR FILTRATION RATE (GFR)

Glomerular filtration rate refers to the rate in ml/min at which a substance is cleared from the circulation by the glomeruli. The ability of the glomeruli to filter a substance from the blood is assessed by clearance studies. If a substance is not bound to protein in plasma, is completely…

RENAL BIOPSY: INDICATIONS, CONTRAINDICATIONS, COMPLICATIONS AND PROCEDURE

Renal biopsy refers to obtaining a small piece of kidney tissue for microscopic examination. Percutaneous renal biopsy was first performed by Alwall in 1944.
