What is the Thyroid Check-up

The Thyroid Check-up is a panel of serological tests which analyse the main parameters of thyroid function and allow the detection of thyroid disease.

  • The tests included in the Basic Thyroid Check-up are: FT3, FT4 and TSH.
  • The tests included in Thyroid Check-up Plus are: FT3, FT4, TSH, thyroglobulin (TG), thyroglobulin antibodies and thyroid peroxidase antibodies.

The Thyroid Check-up is recommended for men and women:

  • When they have symptoms associated with hypothyroidism, such as fatigue, depression or poor memory;
  • When they have symptoms associated with hyperthyroidism, such as weight loss, hyperactivity, irritability, palpitations or excessive sweating;
  • When there is a family history of thyroid disorders;
  • For checking thyroid function in pre- and postmenopausal women;
  • For checking the physiological changes in thyroid function in women during pregnancy and breastfeeding

The thyroid and thyroid diseases

The thyroid is an endocrine gland which is responsible for producing the hormones triiodothyronine (T3), thyronine (T4) and calcitonin. The first two regulate the body’s metabolic balance, by promoting the transformation of food into energy; the last is involved in the correct metabolism of calcium.

Thyroid diseases are thyroid dysfunctions characterised by abnormal levels of thyroid hormones in the blood. We talk about hyperthyroidism when there is a low concentration of TSH in the blood and high values of FT3 and FT4. When the TSH value is high and the FT3 and FT4 levels are low, we talk about hypothyroidism, a condition associated with a decrease in thyroid function. Hashimoto’s thyroiditis is one of the main causes of hypothyroidism. Graves’ disease is a form of hyperthyroidism.

How is the Thyroid Check-up carried out?

The Thyroid Check-up is carried out on a collection of venous blood.
