Prealbumin
Panel: Liver Function Tests · All liver function tests
Typical adult reference range
| Conventional units | 20–40 mg/dL |
| SI units | 200–400 mg/L |
Ranges vary between laboratories and methods — compare your result with the range printed on your own report.
What a high or low result can mean
High prealbumin: high values are uncommon.
Low prealbumin: low values may occur with malnutrition, inflammation, or liver disease.
These are associations, not a diagnosis: the same result can have several causes, and your clinician interprets it with the rest of your results and history.
Good to know
Also called transthyretin; it falls during acute inflammation, which limits its use as a nutrition marker.

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
