Urine Protein Excretion
Creatinine clearance is rarely measured nowadays and has been
replaced by 51Cr EDTA or DTPA clearances in selected cases.
For most purposes, a sufficiently accurate estimate of creatinine
clearance can be calculated from the Schwartz formula: Creatinine Clearance (ml/min/1.73m2) = 40
x Height (cm) / Serum Creatinine (umol/l)
DTPA or 51CrEDTA clearances (selected cases only)
Urine microscopy and culture ( Mid- stream or Bag specimen
initially, not SPA as haematuria cannot be interpreted in SPA
specimens). Phase contrast microscopy for red cell morphology
(glomerular or non-glomerular morphology)
Virology (selected cases only)
