ALP Test Swab measures Alkaline Phosphatase (ALP) activity in milk and other dairy products. The 5-minute test verifies pasteurization efficiency to meet regulatory standards and demonstrates the absence of raw milk. It is a rapid bioluminogenic method that determines the level of ALP enzyme via the conversion of Relative Light Units (RLUs) to milliunits per liter (mU/L) of ALP in pasteurized milk samples. ALP Test Swab is intended for use with pasteurized liquid milk and dairy products.

ALP test swab is designed for detecting Alkaline Phosphatase (ALP) residual in milk and dairy products through chemiluminescent reaction. Residual ALP in the sample catalyzes the hydrolysis of the phosphate group from the chemiluminescent substrate. Subsequent spontaneous molecular decomposition generates luminescent signals. The emitted light can be detected, and measured RLU values positively correlate with ALP activity, allowing quantitative detection by the ATP3500 Luminometer.
