Guides for autoimmune testing

What Do TSH, T3, and T4 Mean on a Thyroid Panel?
A thyroid panel usually reports three things: TSH, a signal from your pituitary gland, and T4 and T3, the two hormones the thyroid actually makes. TSH tells the thyroid how hard to work, so it often shifts before the hormone levels do. Read together, the three numbers show whether the gland and its control signal are in step.
What Blood Tests Relate to Autoimmune Conditions?
No single blood test diagnoses an autoimmune condition. Testing usually combines broad markers, such as an ANA test, CRP or ESR and a complete blood count, with antibody tests aimed at one organ, like thyroid peroxidase antibodies for the thyroid. Which tests make sense depends on symptoms, so the choice sits with a clinician.
