Reference ranges
Albumin reference range
Reference ranges describe the interval a laboratory prints next to your result. They are not a diagnosis of what is “normal” for you personally — your clinician interprets results in context.

What Albumin measures
Albumin helps carry substances through the blood and maintain fluid balance. Labs report its concentration in serum or plasma.
Why ranges differ
Laboratories set their own reference intervals using their methods, equipment, and population data. That is why the range on your Quest report may differ from a LabCorp report — always use the interval printed on your source document.
Common units
Albumin is often reported in g/dL. Confirm units on your original report before comparing values across time.
