For In Vitro Diagnostic Use.

The MicroVue BAP EIA provides a quantitative measure of bone-specific alkaline phosphatase (BAP) activity in serum. BAP is an enzyme produced by osteoblasts, the cells responsible for bone formation. The MicroVue BAP immuno***** provides a quantitative measure of bone-specific alkaline phosphatase (BAP) activity in serum as an indicator of osteoblastic activity.

Measurement of BAP is intended for use as an aid in the:

• management of postmenopausal osteoporosis and Paget's disease;
• monitoring of postmenopausal women on hormonal or bisphosphonate therapy;
• prediction of skeletal response to hormonal therapy in postmenopausal women.
