Quick, accurate and easy-to-use self-test that can performed in the comfort of your own home.

Thyroid disorders are one of the most prevalent medical conditions in the world, particularly for women, with an increasing rate of the population suffering under active thyroid (hypothyroidism).

The symptoms of hypothyroidism include feeling tired and lethargic, weight gain, dry skin and brittle hair, becoming forgetful and sometimes depressed, feeling cold and enduring constipation as well as menstrual irregularities in women.

Thyroid stimulating hormone (TSH), which is secreted by pituitary, regulates and controls the activity of the thyroid gland. Therefore, a raised TSH level indicates an under active thyroid and this is the principle on which Check4® Underactive Thyroid is based for the detection of the hypothyroidism condition.

Check4® Underactive Thyroid is a rapid immunodiagnostic test for the detection of increased TSH levels and therefore for hypothyroidism screening from a finger prick blood sample.

How does the Check4® Underactive Thyroid test work?

The thyroid stimulating hormone (TSH) is activating thyroid gland. Therefore a TSH level over 5 μIU/mL in case of a positive result, indicates most probably an under active thyroid (hypothyroidism).

When should the Check4® Underactive Thyroid test be used?

In case of hypothyroidism symptoms such as feeling tired, depressed or cold regularly, weight gain, dry skin, brittle hair, enduring constipation or menstrual cycle irregularities in women, it is recommended to perform Check4® Underactive Thyroid screening test.
The Check4® Underactive Thyroid test can be used any time of the day. However, the Check4® Underactive Thyroid test should not be performed in case of hormonal thyroid medical treatment.

Can the result be incorrect?

The results are accurate as far as the instructions are carefully respected. Nevertheless, the result can be incorrect if the Check4® Underactive Thyroid test gets wet before test performing or if the quantity of blood dispensed in the sample well is not sufficient. The plastic pipette provided in the box allows making sure the collected blood volume is correct.

How do you interpret the test if the colour and the intensity of the lines are different?

The colour and intensity of the lines have no importance for result interpretation. The lines should only be homogeneous and clearly visible. The test should be considered as positive whatever the colour intensity of the test line (T) is.

What is the line that appears under the mark C (Control) for?

When this line appears, it only means that the test was performing well.

If I read the result after 15 minutes, will the result be reliable?

No. The result should be read within 10 minutes after adding the diluent. The result is reliable up to 15 minutes.

What do I have to do if the result is positive?

If the result is positive, it means that the TSH level in blood is higher than the norm (5μIU/mL) and that you should consult a doctor to show the test result. Then, the doctor will decide whether additional analysis should be performed.

What do I have to do if the result is negative?

If the result is negative, it means that the TSH level is below 5μIU/mL and is within the norm. However, if the symptoms persist, it is recommended to consult a doctor.

How accurate is the Check4® Underactive Thyroid test?

The Check4® Underactive Thyroid test is accurate and has been used for more than 10 years by professionals (hospitals, laboratories) in the field. Evaluation reports show an overall agreement of at least 95.5% with reference methods. Although this test is reliable, false positive or false negative results could be obtained.
