Serum or plasma for creatinine measurements; see Creatinine - serum, plasma.
The patient should not eat a cooked meat meal for 4 – 6 hours prior to testing.
Estimated GFR (eGFR) is a derived value.

Assessment of glomerular filtration rate, which is the main indicator of kidney function.
Moderate, severe or end-stage reduction in GFR persisting for more than 3 months indicates Chronic Kidney Disease. Rapid reductions may indicate acute renal failure.
