A luminescent bioassay for thyroid blocking antibodies

Thyroid blocking antibodies (TBAb) have a role in the development of hypothyroidism and in the neonate are responsible for transient hypothyroidism. Specific measurement of TBAb requires a bioassay, but current methods are lengthy and cumbersome. We describe a rapid luciferase‐based method for the detection of TBAb using the lulu* cell line which is suitable for the provision of a clinical service
