Table 2

Laboratory and thyroid uptake scan results at time of presentation for thyroiditis patients.

Laboratory test	Normal value	Mean ± SD	Range
FT4 (pmol/L)	10.3–25.8	37.8±20.5	(13.2–100)
FT3 (pmol/L)	4.6–9.2	17.1±7.9	(6.8–29)
TSH (mIU/L)	0.25–5	0.3±0.4	(0.005–1.83)
ESR (mm/h)	3–9	53.1±37.3	(6.0–144.0)
Thyroid uptake and scan (%)	Up to 2	0.4±0.36	(0.00–1.85)

FT4: free thyroxine; FT3: free triiodothyronine; TSH: thyroid stimulating hormone; ESR: erythrocyte sedimentation rate.
