The enzyme alkaline phosphatase (ALP, alkaline phenyl phosphatase) is a phosphatase with the physiological role of dephosphorylating compounds. The enzyme is found across a multitude of organisms, prokaryotes and eukaryotes alike, with the same general function, but in different structural forms suitable to the environment they function in. Alkaline phosphatase is found in the periplasmic ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Alkaline phosphatase (ALP) is an enzyme in the cells lining the biliary ducts of the liver. It can also be found on the mucosal epithelium of the small intestine, proximal convoluted tubule of the kidneys, bone, liver, and placenta. It plays an important role in lipid transposition in small intestines and calcification of bones. 50% of all the ...
Elevated alkaline phosphatase occurs when levels of alkaline phosphatase (ALP) exceed the reference range. This group of enzymes has a low substrate specificity and catalyzes the hydrolysis of phosphate esters in a basic environment. The major function of alkaline phosphatase is transporting chemicals across cell membranes. [1]
Alkaline phosphatase levels are usually high in hyperparathyroidism due to high bone turn over. In primary hyperparathyroidism, levels may remain within the normal range, but this is inappropriately normal given the increased levels of plasma calcium. [citation needed]
Blood tests on patients with OFC generally show high levels of calcium (normal levels are considered to range between 8.5 and 10.2 mg/dL, [25] parathyroid hormone (levels generally above 250 pg/mL, as opposed to the "normal" upper-range value of 65 pg/mL [26]), [27] and alkaline phosphatase [2] (normal range is 20 to 140 IU/L [28]).
It’s estimated that 1% of Americans over the age of 12 have hyperthyroidism (also known as an overactive thyroid), a condition that occurs when your body produces more thyroid hormone than ...
It is defined as the quantity of alkaline phosphatase that liberates 1 mg of phosphate ion during the first hour of incubation with a buffered substrate containing sodium β-glycerophosphate. [1] This technique was the first test to measure blood alkaline phosphatase levels, and was developed by Aaron Bodansky in the early 1930s. [2]
