Q: Can blood tests detect dysfunctions? What are the most effective tests for indicating the presence of thyroid disease?


A:  Blood tests detect both defect and excess alterations in thyroid function. The exams performed include TSH (thyroid-stimulating hormone or whose action is to stimulate the functioning of the thyroid) and free thyroid hormones FT3 and FT4 (synthesized by the thyroid). In suspicion of specific diseases,blood tests can be useful for determining the antibody dosage against thyroid disease (Tg-Ab, Ab-TPO, TRAB).
