The card shows an example result of 9.7 ng·mL⁻¹, which is 2.69 SD below the mean.

What it measures

Procollagen type I N-terminal propeptide is cut off as osteoblasts lay down new type I collagen, the main protein in bone. Its level tracks how much new bone is being built.

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, healing fractures, or bone disease.
  • Low — Suggests slow bone formation, with a higher risk of bone loss.
