An amino acid used to make thyroid hormones, dopamine, and adrenaline.
Tyrosine is an amino acid your body can make from phenylalanine, so it is non-essential unless that pathway is impaired. It is the starting material for dopamine, adrenaline, noradrenaline and thyroid hormones, and for the pigment melanin.
Plasma tyrosine is part of a full amino acid profile. It is read alongside phenylalanine, since the two are linked. Unusual levels can point toward inherited disorders of tyrosine breakdown or affect the phenylalanine to tyrosine balance, 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) |
|---|---|
| Tyrosine | 28 to 87 |
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.
