How is Thyroid disease diagnosed?
Thyroid disease must be diagnosed and treated as soon as possible. To check thyroid function, doctors may request one or more blood tests.
TSH (Thyroid Stimulating Hormone)
TSH (thyroid-stimulating hormone) levels in the blood are measured in this test. The anterior pituitary gland produces TSH, which activates the thyroid. This test is used to detect hypothyroidism and hyperthyroidism, as well as to screen infants for hypothyroidism and track thyroid medication.
Thyroid gland function and thyroid disorders, such as hypothyroidism and hyperthyroidism, are assessed using this test. Free T4 is also used to diagnose babies with congenital hypothyroidism.
T4 in the blood is almost entirely linked to protein. The remaining portion is free (unbound) and is the hormone's physiologically active form. This test determines how much free T4 is present in the blood.
T3 Free and Total
It aids in the assessment of thyroid gland function and the diagnosis of thyroid disorders such as hyperthyroidism. It also aids in the monitoring of the success of thyroid problem medication.
T3 is almost entirely linked to protein in the blood. The remaining portion is free (unbound) and is the hormone's physiologically active form. This test determines the amount of free T3 and total T3 in the blood (bound and unbound).
This test detects thyroid antibodies in the blood and aids in the diagnosis and monitoring of autoimmune thyroid illnesses, as well as the differentiation of these from other types of thyroid disease.
Antibodies are proteins produced by the immune system in order to combat external invaders such as viruses and bacteria. Thyroid antibodies come in a variety of forms.
Thyroid peroxidase (TPO) antibodies: Antibodies like these can indicate Hashimoto thyroiditis or Graves' disease.
Thyroglobulin antibodies (Tg): Graves' disease and Hashimoto thyroiditis can both be indicated by these antibodies. Tg and TPO antibodies are commonly found in persons with Hashimoto thyroiditis.
Thyroid-stimulating hormone receptor antibodies (TSHR): Grave's disease can be indicated by these antibodies.
Thyroid scans A specialised imaging process used to diagnose thyroid gland anomalies and assess thyroid function in various locations of the thyroid gland.
Ultrasound An imaging scan of the thyroid to look for abnormalities such as cysts, nodules, or malignancies.
