Test includes: |
Creatinine, estimated GFR. | |
Methodology: |
Enzymatic |
|
Synonyms: |
Creatinine with eGFR, creatinine with GFR, CREATB, Creatinine-S Creatinine with estimated glomerular filtration rate
|
|
Clinical significance: |
Serum creatinine is useful in the evaluation of kidney function and in monitoring renal dialysis. An estimated glomerular filtration rate (eGFR) will accompany all serum or plasma creatinine results. | |
