## In brief

- A study published in JAMA Internal Medicine found that fasting duration had a minimal effect on most routine laboratory tests.
- The finding applies to most routine tests, not necessarily all of them.
- JAMA's current issue reported the study on 2026-11-10.

## Why it matters

Clinicians and patients can judge more precisely whether the length of fasting before routine blood tests needs strict control, since it changes most results only minimally.
