Urine Amylase

Code:
UAMY

Sample Type:

Random urine – plain, no preservative

Ref Ranges/Units:

In macroamylase, FE amylase <1%

Turnaround:

Same Day

Stability:

2 days at 15‑25°C  
10 days at 2‑8°C  

Special Precautions/Comments:

Additional Information:

Measurement of urine amylase (alongside a paired serum sample) can be used to calculate the fractional excretion of amylase. This can be used to identify positive interference in serum caused by macroamylase.

 

FE amylase (%) = [(urine amylase x serum creatinine)/(serum amylase x urine creatinine)] x 100

In macroamylase, FE amylase <1%
