The short answer
Total Protein is measured with a standard blood draw after an 8–12 hour fast. A typical reference range is 6.30 – 8.30 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.

Total Protein Reference Range

Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
