Alkaline phosphatase.placental/Alkaline phosphatase.total
Measures the proportion of alkaline phosphatase enzyme originating from the placenta.
Why This Biomarker Matters
Elevated placental ALP may signal pregnancy complications or certain malignancies. Interpreting this result requires clinical context and additional testing for accurate diagnosis.
Overview
Alkaline phosphatase (ALP) is an enzyme found throughout the body, with high levels in the placenta during pregnancy. The placental fraction test measures the proportion of ALP coming specifically from the placenta. Elevated placental ALP can indicate pregnancy complications or certain cancers. This test is sometimes used in pregnancy monitoring and cancer screening, though it's less commonly ordered today due to newer diagnostic methods.
