The card shows an example result of 8.9 ng·mL⁻¹, which is 2.26 SD below the mean.

What it measures

Osteocalcin is made by osteoblasts, the cells that build bone. Some of it enters the blood, so its level reflects how active bone formation is.

Direction↓ Bad — a lowered value is the concern.

The mean is (low + high) / 2 and the SD is (high − low) / 4, so the healthy range covers Z from −2 to +2.

Reading the result

  • High — Not the concern this panel tracks. High values can mean fast bone turnover.
  • Low — Suggests slow bone formation. It is linked to low bone density and, in some studies, to poorer glucose control.

Notes

  • It varies through the day and is unstable once drawn, so samples must be handled carefully.
