Test Details
Methodology
Immunochemiluminometric assay (ICMA)
Result Turnaround Time
3 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Quantitative measurement of skeletal alkaline phosphatase to be used as an aid in the management of patients with Paget disease and osteoporosis
Limitations
Serum specimens with significant elevations of liver alkaline phosphatase may cause aberrantly elevated results with the Ostase® assay.
