Significance of Testing Anti-Thyroid Autoantibodies in Patients with Deranged Thyroid Profile

Table 2

Comparison of mean ranks of anti-TPO and anti-TG antibodies between TSH and free T4 normal and deranged groups.

	TSH				Free T4
	Normal TSH (0.4–4.5 mIU/ml)	Deranged TSH (<0.4 or >4.5)	value	OR (95% CI)	Normal T4 (8–21 pmol/l)	Deranged T4 (<8 or >21)	value	OR (95% CI)
Anti-TPO antibodies mean rank	137.76 ()	196.81 ()	0.001	4.3 (2.62–7.23)	68.93 ()	77.5 ()	0.286	2.0 (0.93–4.45)
Anti-TG antibodies mean rank	38.02 ()	40.96 ()	0.098	4.2 (1.44–12.2)	20.76 ()	19.96 ()	0.840	1.27 (0.29–5.46)
