Laboratory: Clinical Biochemistry
Test Name:
ALKALINE PHOSPHATASE (ALP), Rural Sites (ORTHO), excluding Westman Lab - (P)
Test Code: --
Clinical Information:
Alkaline phosphatase levels are elevated during pregnancy due to placental alkaline phosphatase.  Values are 2 times normal in the third trimester.
Collection Devices:
Specimen Required:

Plasma: 2.0 mL

Serum: 2.0 mL
Reference Values:
0 - 12 mo: 140 - 424 U/L

Patients with low alkaline phosphatase levels:  A low level can occur in various medical conditions and may be a marker for hypophosphatasia, a now potentially treatable disorder of bone mineralization.  For further information please contact the metabolic geneticist on call through HSC paging (204-787-2071).
