Alkaline Phosphatase FS (IFCC mod. 37°C)

Product Number : 1 0441


Alkaline Phosphatase (AP), a hydrolytic enzyme acting optimally at alkaline pH, exists in blood in numerous distinct forms which originate mainly from bone and liver, but also from other tissues as kidney, placenta, testes, thymus, lung, and tumors. Physiological increases are found during bone growth in childhood and in pregnancy, while pathological increases are largely associated with hepatobiliary and bone diseases. In hepatobiliary diseases, they indicate obstruction of the bile ducts as in cholestasis caused by gall stones, tumors, or inflammation. Elevated activities are also observed in infectious hepatitis. In bone diseases, elevated AP activities originate from increased osteoblastic activity as in Paget’s disease, osteomalacia (rickets), bone metastases, and hyperparathyroidism.

Increased in

  • Intrahepatic cholestasis, (example: liver infiltrates by carcinoma, leukemia, tuberculosis, sarcoidosis, amyloidosis, fibrosis (cirrhosis)).
  • Extrahepatic cholestasis (eg, bile duct stones, neoplasms, atresia)
  • Osteoblastic disease, (eg malignancy, secondary hyperparathyroidism, Paget’s disease)
  • Tumor
  • Pregnancy

Decreased in

  • Hypophosphatasemia: a relatively rare inherited disorder that is asymptomatic or may be associated with arthritis of the weight-bearing joints
  • Hypothyroidism
  • Scurvy
  • Severe anemia
