The card shows an example result of 12.8 ng·mL⁻¹, which is 2.35 SD below the mean.
What it measures
Brain-derived neurotrophic factor helps nerve cells survive, grow, and form new connections. Most in the blood is stored in platelets.
Reference range
| Field | Value |
|---|---|
| Abbreviation | BDNF |
| Group | Nerve and blood vessel |
| Unit | ng·mL⁻¹ |
| Healthy range | 15–40 |
| Mean | 27.5 |
| SD | 6.25 |
| 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.
- Low — Linked to depression, cognitive decline, and poor metabolic health.
Notes
- Serum values are much higher than plasma values, because platelets release BDNF as a sample clots.
- Exercise tends to raise it.
