Why Self Test

ThyroScreen FAQ's

Q

How does ThyroScreen™ work?

A

ThyroScreen™ gives a positive result if your Thyroid Stimulating Hormone (TSH) level is above 5μIU/ml. TSH controls the amount of thyroxine produced by the thyroid gland and a raised TSH level above this cut-off indicates that you are likely to have an underactive thyroid (hypothyroidism).

Q

When should the test be used?

A

If you have one or more of the symptoms of hypothyroidism including feeling tired and lethargic, weight gain, dry skin and brittle hair, becoming forgetful and sometimes depressed, feeling cold and constipation as well as menstrual irregularities in women, then taking the ThyroScreen™ test for the condition is recommended. The test can be performed at any time of the day but is not recommended if you are already undergoing treatment for a thyroid condition.

Q

Is the test result correct?

A

ThyroScreen™ has been validated against laboratory tests and is accurate provided the instructions are followed carefully. Please note however that the test result can be adversely affected if the cassette gets wet before the test is performed or if insufficient blood is used. It is important to ensure that the correct volume of blood is collected, as indicated by the black line marked on the pipette.

Q

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

A

The colour and intensity of the test lines are of no importance in the interpretation of the result. The lines only need to be uniform and clearly visible and a line of any colour intensity by the 'Test' mark should be regarded as positive.

Q

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

A

No, the result should be read within 10 minutes of adding the test diluent and is reliable only up to 15 minutes.

Q

What should I do if the test result is positive?

A

ThyroScreen™ is a screening device for hypothyroidism and a positive test result indicates that you have an under active thyroid gland. We would recommend that you should seek medical advice from your doctor who will conduct further tests and take into account any symptoms of the condition that you may have before making a definitive diagnosis.

Q

What should I do if the test result is negative?

A

A negative test result indicates that it is very unlikely that you have an under active thyroid gland. However, as no test is 100% effective we would recommend that you consult your doctor if you have worrying symptoms.
