imported lipase assay kit (DLPS-100); Bioassay Systems (Hayward, CA, USA). Coloration
intensities were evaluated at 550 nm and the result was represented as
U/l. The following formula was used to calculate the serum lipase
activity:
Lipase activity = (Δabs/min) Calicrator – (Δabs/min) Blank / (Δabs/min) Assay –
(Δabs/min) Blank
where, (Δabs/min) Assay = Rate of change/min (sample)
(Δabs/min) Blank = Rate of charge/min (blank)
(Δabs/min) Calibrator = Rate of change/min for Lipase color calibrator.
