Elevated alkaline phosphatase occurs when levels of alkaline phosphatase (ALP) exceed the reference range. This group of enzymes has a low substrate specificity and catalyzes the hydrolysis of phosphate esters in a basic environment. The major function of alkaline phosphatase is transporting chemicals across cell membranes. [1]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The level of alkaline phosphatase in the blood is checked through the ALP test, which is often part of routine blood tests. The levels of this enzyme in the blood depend on factors such as age, sex, or blood type. [2] Blood levels of alkaline phosphatase also increase by two to four times during pregnancy. This is a result of additional ...
alkaline phosphatase (sometimes abbreviated as ALP) ALL: acute lymphoblastic leukemia allergies: ALP: alkaline phosphatase (sometimes abbreviated as Alk phos) ALPS: autoimmune lymphoproliferative syndrome: ALS: amyotrophic lateral sclerosis, also known as motor neurone disease ('MND), Lou Gehrig's disease or Charcot disease advanced life ...
ALP level can be elevated due to bone turnover. Additionally further tests can be completed to rule out other causes and complications of hyperparathyroidism including a 24-hour urinary calcium for familial hypocalciuric hypercalcemia, DEXA scan to evaluate for osteoporosis , osteopenia , or fragility fractures , and genetic testing.
The first clinical manifestation of Paget's disease is usually an elevated alkaline phosphatase in the blood. [7] Paget's disease of right pelvic bone. Man of 80 years age. Paget's disease may be diagnosed using one or more of the following tests: Pagetic bone has a characteristic appearance on X-rays. A skeletal survey is therefore indicated.
The decrease in ALP activity leads to an increase in pyridoxal 5’-phosphate (PLP), which is the major form of Vitamin B6, in the blood, although tissue levels of Vitamin B6 may be unremarkable [30] and correlates with disease severity. [31] Urinary inorganic pyrophosphate (PPi) levels are elevated in most hypophosphatasia patients and ...
Alkaline phosphatase, placental type is a membrane-bound glycosylated dimeric enzyme, also referred to as the heat-stable form, that is expressed primarily in the placenta, although it is closely related to the intestinal form of the enzyme as well as to the placental-like form.
