A metabolite of glycine metabolism.
Sarcosine is a small amino acid made and used in the metabolism of glycine, one of the simplest amino acids. It sits in the pathway that recycles methyl groups, linking it to folate and choline metabolism. It appears in plasma in small amounts.
Sarcosine is reported as part of a full amino acid profile, mainly as a clue rather than a routine health marker. A raised level can point toward sarcosinemia, a usually harmless inherited variant, so it is read in the context of the whole profile.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
Adult fasting plasma, guidance only:
| Analyte | Typical adult range (µmol/L) |
|---|---|
| Sarcosine | 0 to 4 |
Ranges vary by laboratory and assay and are read as part of the full amino acid profile.
Results are affected by recent diet, recent protein intake, fasting state and the time of day the sample is taken.
