Inulin clearance rate

Inulin is an exogenous plant polysaccharide that does not participate in metabolism in the body, can pass freely through the glomerulus, all through the glomerular filtration, the renal tubules are not secreted or reabsorbed, it is ideal for measuring glomerular filtration function. Source material. Cin can accurately reflect GFR. This test has become the standard method for clinical examination of glomerular filtration. However, it has also been suggested that in the case of tubular dysfunction, inulin can retrograde to the renal tubules and affect GFR. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Found in acute glomerulonephritis, cardiac insufficiency, chronic glomerulonephritis, renal arteriosclerosis, advanced hypertension, pyelonephritis, early hypertension. Normal value: Inulin clearance rate (male): 99-149ml/min Inulin clearance rate (female): 107-131ml/min Above normal: normal. negative: Positive: Tips: Drink plenty of water to ensure natural urination. It is not advisable for diabetic patients to perform this test because glucose interferes with the test. Normal value Male 124 ± 25 ml / min, female 119 ± 12 ml / min. Clinical significance Abnormal results inulin clearance was significantly reduced. The person in need of examination has acute glomerulonephritis, cardiac insufficiency, chronic glomerulonephritis, renal arteriosclerosis, advanced hypertension, pyelonephritis, and early hypertension. Low results may be diseases: acute glomerulonephritis, chronic glomerulonephritis, chronic heart failure Drink plenty of water to ensure natural urination. It is not advisable for diabetic patients to perform this test because glucose interferes with the test. Inspection process One injection method, 100 g/L of inulin (sterile injection) 100 ml was intravenously administered after urination, and the injection was completed within 10 minutes at a uniform rate. Immediately drink 500ml of water, after 30min, urinate and discard, immediately draw blood (P0), and collect the first urine (U1) after 15min. Blood was drawn 10 minutes later (P1), and after 15 minutes, the second urine (U2) and immediate blood draw (P2) were collected. Not suitable for the crowd It is not advisable for diabetic patients to perform this test because glucose interferes with the test. Adverse reactions and risks No.
