LP15346-7   Alkaline phosphatase
Alkaline phosphatase (ALP, ALKP) is a hydrolase enzyme responsible for removing phosphate groups from many types of molecules, including nucleotides, proteins, and alkaloids. ALP is present in all tissues throughout the entire body, but is particularly concentrated in liver, bile duct, kidney, bone, and the placenta. Humans and most other mammals contain the following ALP isozymes: ALPI (intestinal), ALPL (tissue non-specific, liver/bone/kidney), and ALPP (placental, aka Regan isozyme).

The normal range of alkaline phosphatase is 20 to 140 IU/L. High ALP levels are present in children and pregnant women, if bile ducts are blocked, and in the presence of osteoblast activity, such as with Paget's disease of the bone. Lowered levels of ALP are less common than elevated levels and occurs in various conditions, including aplastic and pernicious anemias, chronic myelogenous leukemia, Wilson's disease, children with severe enteritis, and postmenopausal women on estrogen therapy for osteoporosis.

Mapping Guidance LOINC This term was made to accommodate a laboratory system outside of the US. LOINC currently discourages the use of specimens combining ser/plas and blood in one term (as ser/plas/bld) for two reasons. First, practices usually want to distinguish the two on ordering since whole blood usually implies a point of care test and ser/plas usually implies sending to another location. Second, whole blood tests are usually classified as low complexity (waived) under CLIA regulations, and because waived tests are excluded from the annual COLA report of testing volume (required by the Centers for Medicare and Medicaid Services) and ser/plas tests are not, the two have to be distinguished.
