The combined branched-chain amino acids that fuel and build muscle.
The branched-chain amino acids are leucine, isoleucine, and valine. They are essential, meaning the body cannot make them and must get them from food. They are important for building muscle, providing energy, and signalling protein synthesis. This result reports their combined total.
The total is measured as part of a plasma amino acid profile. It gives a single picture of branched-chain amino acid status, which links to protein intake, muscle metabolism, and insulin-related pathways. It is read alongside the individual values and the rest of the panel.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
| Group | Adult fasting plasma range (sum) |
|---|---|
| Adults | Approximately 250 to 580 µmol/L |
This total is the sum of leucine, isoleucine, and valine. Amino acid ranges vary by laboratory and method, and are best read as part of the full plasma amino acid profile.
Recent protein intake, BCAA or protein supplements, fasting state, and time of day affect the result. A fasting morning sample gives the most reliable reading.
