Holidays are celebrated for all sorts of reasons. Some honor heroes, others commemorate religious events, but April 1 stands out as the only holiday that celebrates foolishness. April Fools' Day, or All Fools Day, is an odd celebration with a strange history.
Alkaline phosphatase is an enzymatic protein found in liver, intestine, placenta and bone. The normal adult range of alkaline phosphatase is 41 to 133 IU per liter of blood, and these values vary among laboratory and method, according to The Pocket Guide to Diagnostic Tests..
Liver-derived alkaline phosphatase (ALP) has some cross-reactivity in this assay: 100 U/L of liver ALP activity gives a result of 2.5 ï­g/L to 5.8 ï­g/L. Accordingly, serum specimens with significant elevations of liver ALP activity may yield elevated results.
