Description:This historic 1966 image depicted a laboratory technician using a manual method for conducting an alkaline phosphatase (ALP) determination.
A check on the blood levels for alkaline phosphatase is an important measure, for this enzyme is predominantly produced by the celles lining the bile duct. Bile, produced in the liver, travels through the bile ducts into the small intestine, where it delivers the ALP, which is subsequently, absorbed by the small intestine, and enters the blood stream. Therefore, a low blood level of ALP could be an indication of a possible problem with the hepatobiliary system.

Modern day protocols now call for the laboratorian executing such tasks, to wear personal protective equipment (PPE) including safety goggles, gloves, and a face mask.
