Thyroid function tests

Thyroid disorders affect about 30% of Lithuania’s population. Morbidity in women is 10 times higher than in men. Thyroid function disorders develop very slowly and at the onset of the condition, people often feel healthy even though the changes are already happening. 

Thyroid blood tests are the easiest and quickest way to assess thyroid health and detect thyroid disorders. Thyroid hormones are involved in the metabolism of the whole body and play an important role in the functioning of the cardiovascular, nervous, integumentary, gastrointestinal, renal, reproductive systems. Our beauty, body mass, energy, thinking, and fertility rely on successful functioning of the thyroid.

We recommend undergoing thyroid tests if:

  • you have a genetic predisposition for thyroid disorders (examining all members of the family is recommended);
  • you have had thyroid disorders before;
  • you have had radiation therapy;
  • you are planning a pregnancy or have been trying to get pregnant for over a year, or you are pregnant 6 months after giving birth;
  • you go through the menopause;
  • you take medication which affects thyroid function (contraceptives, hormone replacement therapy, sex hormones, glucocorticoids, etc.);
  • you have cardiovascular diseases or autoimmune diseases (diabetes, celiac disease, rheumatoid arthritis, adrenal insufficiency, lupus, vitamin B12 deficiency anaemia, etc.),
  • you are over 35 years old—have a screening once every 5 years;
  • you are over 60 years old—have a screening once a year;
  • you are a heavy smoker.
    At the first thyroid screening, two thyroid hormones are usually tested:
  • free thyroxine (FT4)
  • thyroid-stimulating hormone (thyrotropin, TSH)

These tests give initial information about thyroid function.
In order to get a more detailed picture and detect thyroid function disorders, an immune-mediated thyroid disorder or potential cancer, we recommend additional testing for the following hormones:

  • free triiodothyronine (FT3)
  • antithyroid microsomal antibodies (ATPO)
  • thyroglobulin

Thyroid disorders are usually diagnosed when a number of related blood tests and a thyroid ultrasound have been performed in addition to the thyroid function tests.

You do not need to schedule an appointment in advance, you can simply check in at reception and request to be tested.

Why it is worth

To be examined at our Centre?

  • Your tests will be properly performed.The quality of our lab services has been acknowledged with our ISO 15189 accreditation.
  • Our lab technicians will comment on the test results. Few labs in the country provide this service.
  • We can do additional thyroid tests, if needed, from the same blood sample taken up to 7 days ago. This is especially relevant for children or patients living in other towns!
  • There is no risk of damaging or mixing up test samples in transportation, which statistically is one of the leading causes for ruined blood samples in labs.

Good to know

The most common symptoms are the following:

  • chronic fatigue
  • feeling of weakness
  • irritability
  • agitation
  • mood swings
  • depression
  • sleepiness
  • apathy
  • a low pulse
  • hand tremors
  • excessive sweating
  • heat waves
  • rapid weight loss or weight gain
  • menstrual problems
  • dry skin
  • infertility
  • vision problems
  • increased blood pressure
  • bulging eyes

If you have these symptoms for more than a few weeks with no obvious reason, we recommend scheduling an appointment and having the tests.

Thyroid function test results may be affected by diet, weight changes, pregnancy, stress, medication or other conditions the patient has, therefore, thyroid function tests results might differ in different stages in life.

It can be difficult to interpret thyroid function test results without other tests also being done or if the overall state of health is unknown.

One of the main parameters of thyroid function, thyroid-stimulating hormone (thyrotropin, TSH), fluctuates during the day. Research shows that it peaks during sleep at night and is at its lowest in the second half of the day. Therefore, test results may be different depending on whether the tests are carried out in the morning or afternoon.

Our doctors recommend performing all the tests in the first half of the day, ideally in the morning.

  • The report with the test results is usually prepared in 1 day. It can be picked up at the reception or we can send it via email at your request.
  • Unsure how to interpret the results? Call the lab, phone: (8 5) 247 64 17.
