Bodansky unit

The Bodansky unit is an obsolete measure of alkaline phosphatase concentration in blood. 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]

Other units that were used in the past as a measure of blood alkaline phosphatase levels are King-Armstrong units, Kind-King units, and International units.[3] However, the Bodansky unit and those other units have become outdated, and the current standard for measuring alkaline phosphatase is units per liter (U/L).[3]
