アルカリホスファターゼ
The level of alkaline phosphatase in the blood is checked through the ALP test, which is often part of routine blood tests. The levels of this enzyme in the blood depend on factors such as age, sex, or blood type. Blood levels of alkaline phosphatase also increase by two to four times during pregnancy. This is a result of additional alkaline phosphatase produced by the placenta. Additionally, abnormal levels of alkaline phosphatase in the blood could indicate issues relating to the liver, gall bladder or bones. Kidney tumors and infections as well as malnutrition have also shown abnormal level of alkaline phosphatase in blood. Alkaline phosphatase levels in a cell can be measured through a process called "The scoring method". A blood smear is usually taken and stained to categorize each leukocyte into specific "leukocyte alkaline phosphatase indices". This marker is designed to distinguish leukocytes and determine different enzyme activity from each sample's extent of staining.
