Alkaline Phosphatase (ALP) analysis is a medical test used to evaluate the levels of the alkaline phosphatase enzyme in the blood. This enzyme plays an important role in protein metabolism and is found mainly in the cells of the liver, bones, kidneys, and the placenta in pregnant women. The test is considered a fundamental tool for assessing liver function and bone health, as elevated ALP levels may indicate liver diseases such as hepatitis or bile duct obstruction, or bone-related conditions such as Paget’s disease or rickets. Its levels may also rise naturally during pregnancy due to placental activity. The analysis is also used to help diagnose certain chronic or acute conditions affecting the liver or bones and can be performed alongside other tests to determine the cause of any increase or decrease in ALP levels. Normal ALP values vary depending on age, sex, and overall health status, but significant increases or decreases may require medical follow-up to identify the underlying cause.
