Determination of alkaline phosphatase isozymes is used to diagnose and monitor the treatment of diseases of the liver, bone, intestine and parathyroid glands, to determine the cause of elevated serum alkaline phosphatase, and to differentiate between hepatic or bone causes.

Alkaline phosphatase (ALP) is found in various tissues, including the liver, bone, intestine and placenta. The serum alkaline phosphatase activity is derived from all isoenzymes from these tissues. Serum alkaline phosphatase measurement is used for the differential diagnosis of two groups of pathologies, hepatobilary and bone diseases with elevated osteoblastic activity.

Increased ALP activity occurs in all forms of cholestasis, especially in obstructive jaundice. The liver's response to any form of biliary obstruction consists in the synthesis of more alkaline phosphatase than the adjacent bile duct.

ALP also increases skeletal system disorders that have increased osteoblast activity and remodeling, such as Paget's disease, osteomalacia, fractures, and malignant bone tumors.

Moderate increases in alkaline phosphatase can also be observed in other pathological disorders such as Hodgkin's disease, congestive heart failure, ulcerative colitis, peripheral enteritis and intra-abdominal bacterial infections. 

 

 

Important Note

Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".

Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.

At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
