Patient's question:
Alkaline phosphatase value is 251. What are the possible factors that may cause this symptom? What diseases are suspected? What tests are recommended?Doctor's answer:
Clinically, alkaline phosphatase (ALP) is primarily used for the diagnosis and differential diagnosis of skeletal and hepatobiliary system diseases, especially for the differential diagnosis of jaundice. For elevated serum ALP levels of unknown cause, isoenzyme determination can help identify the organ of origin.Physiological increases:
Children during the physiological period of skeletal development may have ALP activity 1 to 2 times higher than normal adults. Adolescents in the growth phase, as well as pregnant women and individuals after consuming high-fat foods, may also experience elevated levels.
Pathological increases:
(1) Skeletal diseases such as rickets, chondromalacia, bone malignancies, and bone metastases of malignancies;
Hepatobiliary diseases such as extrahepatic biliary obstruction, hepatocellular carcinoma, cirrhosis, and canalicular hepatitis;
Other diseases such as hyperparathyroidism.
