measures the amount of acid phosphatase in a person's blood, and can determine from what tissue the enzyme is coming. For example, it is important to know if the increased acid phosphatase is from the prostate or red blood cells

The phosphatase test in milk measures the amount of phosphatase enzyme in the milk. The phosphatase enzyme should be inactivated by pasteurisation. If the phosphatase test is not negative, there is a problem with pasteurisation or recontamination with unpasteurised milk.

This test requires drawing about 5-10 mL of blood. The patient should not have a rectal exam or prostate massage for two to three days prior to the test.
acid phosphatase levels rise, particularly if the cancer spreads to the bone. One-half to three-fourths of persons who have metastasized prostate cancer have high acid phosphatase levels

bone, liver, spleen, kidney, and red blood cells and platelets. Damage to these tissues causes a moderate increase in acid phosphatase levels.

Depends on what sort of phosphatase your asking about. Phosphatase Test in the Milk industry is to determine if pasteurization is successful. Phosphatase is a naturally occurring enzyme, and helps the body adsorb nutrients such as Calcium. However, this enzyme becomes inactive at temps* used for pasteurization (for killing harmful bacteria in milk). So pretty much if a Phosphatase test is positive, it means that the pasterurization has not been successful. Pasteruization is a mix of both heat and time. generally most bacteria will die at temp of 64 degrees celcius and higher, for 30mins. NB: the higher the temp the sorter the holding time can be. for e.g. 80 degrees celcius for 15mins does the job. Hope this helped answer your question
Employ qualitative inorganic analysis, and perform the test for nitrate.
