GFR
Glomerular filtration rate
eGFR: uses Serum Cr, Age and Sex
Cockcroft and Gault formula: (140-age) x weight (kg) / 0.814 x plasma Cr (umol/L) (X 0.85 if female)
Cr clearance = urine Cr (mmol/L) x urine volume (mL) x 16.7 / plasma Cr (mmol/L) x duration of collection (hours)
(Pt BSA needed to adjust to standard /1.73m2 unit)
Nuc Med GFR: chromium 51 ethylenediaminetetraacetic acid (Cr51 EDTA)
