The card shows an example result of 155.8 ng·mL⁻¹, which is 2.53 SD above the mean.
What it measures
Matrix metalloproteinase-9 breaks down collagen and other parts of the matrix that holds tissue together. Immune cells release it during inflammation and repair.
Reference range
| Field | Value |
|---|---|
| Abbreviation | MMP-9 |
| Group | Bone and mineral |
| Unit | ng·mL⁻¹ |
| Healthy range | 20–140 |
| Mean | 80 |
| SD | 30 |
| 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 — Suggests active tissue breakdown, as in joint, bone, or blood vessel inflammation. It is linked to unstable plaque in arteries.
- Low — Not a concern.
Notes
- Serum and plasma values differ, because blood cells release MMP-9 as a sample clots. Compare like with like.
