1. Laboratory tests commonly used
Projects include urinalysis, renal function, urinary protein of 24 hours, glucose, uric acid, lipids etc, and serum electrolytes (K, Na, Cl, Ca, P, Mg etc), analysis of arterial blood gases, renal imaging etc.
Check the function of glomerular filtration of the main methods are: serum creatinine (Scr), the rate of creatinine clearance (Ccr) and other radionuclides measured GFR etc. The normal value Ccr: 90 ± 10 ml / min. For different groups of people, their values, Scr, Ccr may differ significantly, doctors have to judge correctly.
2. The imaging inspection
Generally only the B-mode ultrasound to exclude stones, renal tuberculosis, renal cystic disease. Some special cases can be made radionuclide renography, intravenous urography, renal CT and magnetic resonance imaging (MRI) and so on. Renogram examination of acute and chronic renal failure in the differential diagnosis useful. As the results showed kidneys segment renogram vessel segment discharge the functions of excretion are poor, they are not generally indicative of CRF, as diagram kidney showed better renal vascular segment, excretory functions poorly, was "obstructive" (parabolic) are generally indicative of acute renal failure exists.
