Albumin levels: what's normal, high and low
The most abundant protein in blood. Made by the liver; reflects nutrition and liver/kidney health.
Medically reviewed by Youmna DiStefano, MD · Last reviewed September 2026
The short answer
Albumin is measured with a standard blood draw after an 8–12 hour fast. A typical reference range is 3.50 – 5.00 g/dL. At TestWell it's $22.99 all-in as Comprehensive Metabolic Panel, results in 1–3 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.
