Creatinine

Description: A renal function test used in eGFR calculation.
High creatinine: Renal diseases and insufficiency with decreased glomerular filtration; urinary tract obstruction; reduced renal blood flow including congestive heart failure, shock and dehydration; rhabdomyolysis can cause elevated serum creatinine.
Low creatinine: Small stature, debilitation, decreased muscle mass, some complex cases of severe hepatic disease can cause low serum creatinine levels. In advanced liver disease, low creatinine may result from decreased hepatic production of creatinine and inadequate dietary protein as well as reduced muscle mass.
Antibiotics containing cephalosporin lead to significant false-positive values if samples are drawn within four hours of a dose.

Includes:
Creatinine, Serum

Patient Instructions: Antibiotics containing cephalosporin lead to significant false-positive values if samples are drawn within four hours of a dose.
