Description
Summary:[Dear Editor,] Wada et al. [1] reported the occurrence of false-positive TSH receptor antibody results in neonates and healthy volunteers using lithium-heparin plasma in a third-generation anti-TSHR platform (Elecsys(R) Anti-TSHR, Roche Diagnostics Ltd., Basel, Switzerland). We encountered a case of discrepant TSH receptor antibody results in an infant with activating TSH receptor mutation. The Chinese male infant was delivered preterm (33 week 5 days) for suspected fetal distress. He had persistent tachycardia after birth and thyroid function tests on day 10 showed a suppressed TSH (100 pmol/L). The mother was clinically and biochemically euthyroid with no personal history of thyroid disease. Family history of thyroid diseases was negative.
