Verdict: REFUTED · 0 sources for, 4 against · Last checked
The claim asserts that blood tests are necessary to diagnose uncomplicated common colds and fevers. Medical literature and clinical guidelines consistently indicate that uncomplicated upper respiratory infections and common viral fevers are diagnosed clinically and resolve with supportive care, rendering routine blood tests unnecessary. The retrieved papers support this by showing that investigations are not generally required for these conditions and that management relies on supportive care.
