Intended use

BAP (bone specific alkaline phosphatase) is a highly specific marker of osteoblast activity during bone remodeling. Measurement of BAP is intended for use as an aid in:

  • management of postmenopausal osteoporosis and Paget’s disease.
  • monitoring postmenopausal women on hormonal or bisphosphonate therapy.
  • predicting skeletal response to hormonal therapy in postmenopausal women.
  • diagnostic analysis metastasis.
