The card shows an example result of 850 ng·mL⁻¹, which is 4.50 SD above the mean.

What it measures

Cartilage oligomeric matrix protein helps hold the collagen in cartilage together. It is released into the blood as cartilage breaks down.

Direction↑ Bad — a raised 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 — Points to cartilage breakdown, as in osteoarthritis or joint injury. It can rise after hard joint loading.
  • Low — Not a concern.

Notes

  • Avoid running or heavy joint loading in the hours before the test.
