The card shows an example result of 18.3 ng·mL⁻¹, which is 4.52 SD above the mean.

What it measures

Myostatin is made by muscle cells and acts as a brake on muscle growth. Higher levels mean a stronger signal to hold back or break down muscle.

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 — Linked to muscle loss with ageing, inactivity, and chronic disease.
  • Low — Not a concern.

Notes

  • Assays differ a lot. Compare values from the same lab.
  • Resistance training tends to lower it.
