- Thyroid function is crucial for maintaining normal metabolic function in adults and for proper neurological development of the fetus. (cdc.gov)
- Thyroid function tests including free T3, free T4 and TSH-IRMA were performed. (biomedcentral.com)
- thus screening vitiligo patients for thyroid function and thyroid antibody seems plausible [ 3 ]. (biomedcentral.com)
- This study aimed to evaluate the relationship between T1-mapping value and thyroid function and determine the usefulness of T1-mapping in identifying thyroid destruction in AIT patients. (scienceopen.com)
- But thyroid function is very complex. (drnorthrup.com)
- Everyone with a thyroid will have some level of TG within their blood, yet there is an average level that the thyroid needs to maintain in order to function normally. (bodahealth.ca)
- General practitioners are well placed to be the primary clinicians overseeing the long-term management of patients with thyroid function abnormalities. (racgp.org.au)
- These features were correlated with the results of serologic and thyroid function tests, and with sonographic data. (lww.com)

Antibody levels1
- For years, many patients and clinicians have been chasing thyroid peroxidase (TPO) and anti-thyroglobulin (TG) antibody levels in an attempt to get them as low as possible or even undectable as a measure of success. (drhedberg.com)
Autoimmunity2
- 3 Approximately 10-20% of the Australian population have evidence of thyroid autoimmunity based on the presence of circulating thyroid autoantibodies, 4 but prevalence may vary with age, sex and ethnicity. (racgp.org.au)
- High levels of autoantibodies against thyroid peroxidase in the patients support the autoimmunity hypothesis of schizophrenia. (nel.edu)
