What the engine reports
Detected clinical pattern
No Biochemical Evidence of Current Thyroid Dysfunction from Entered TSH and FT4
Thyroid-function tests entered are within their reported laboratory reference intervals.
Why this pattern was identified
- TSH and FT4 within reference. TSH 3.2 mIU/L (ref 0.4–4.5) and FT4 1.3 ng/dL (ref 0.8–1.8).
- Symptoms are supportive only. 4 compatible symptoms documented, but normal TSH and FT4 do not support a thyroid cause on their own.
Differentials, pitfalls and contradicting signals
- Non-thyroid causes of the documented symptoms (mood disorder, sleep, anemia, metabolic or medication effects).
