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]
[11] [12] [13] Levels in the third trimester can be as much as 2-fold greater than in non-pregnant women. [11] As a result, ALP is not a reliable marker of hepatic function in pregnant women. [11] In contrast to ALP, levels of ALT, AST, GGT, and lactate dehydrogenase are only slightly changed or largely unchanged during pregnancy. [11]
Arterial levels for drugs are generally higher than venous levels because of extraction while passing through tissues. ... 0.47 [5] 2.1 [5 ... Higher in pregnant ...
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 ...
The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.

It affects 0.5–1.5% of pregnancies in Europe and the US and up to 28% in women of Mapuche ethnicity in Chile. [60] ICP is characterized by severe pruritus and elevated serum levels of bile acids as well as transaminases and alkaline phosphatase. [61]
Alkaline phosphatase allows for mineralization of calcium and phosphorus by bones and teeth. [21] ALPL gene mutation leads to insufficient TNAP enzyme and allows for an accumulation of chemicals such as inorganic pyrophosphate [ 21 ] to indirectly cause elevated calcium levels in the body and lack of bone calcification.
