Hypothyroidism (Underactive Thyroid) occurs when the thyroid gland is not producing a sufficient level of thyroxine (T4) and triiodothyronine (T3).
- Weight gain
- Fatigue or feeling tired all the time
- Slow pulse or heart rate
- Hair loss or thinning
- Poor tolerance of the cold
- Dry, coarse or thickened skin
- Hand tingling or pain (carpal tunnel syndrome)
- Irregular period or low sex drive
- Muscle cramps
- Impaired memory
Hyperthyroidism (Overactive Thyroid) occurs when the thyroid gland produces an excessive level of thyroxine (T4) and triiodothyronine (T3).
- Weight loss
- Fatigue or feeling tired all the time
- Increase or rapid heart rate
- Tremors (usually in the hands)
- Heat intolerance or excessive sweating
- Difficulty sleeping
- Excessive sweating or fever
- Frequent bowel movements or diarrhoea
- Irregular period
- Low sex drive
- Enlarged thyroid gland (goiter)
- Eye condition related to hyperthyroidism
You should consider getting tested if you:
- Have symptoms of an overactive thyroid
- Have symptoms of an underactive thyroid
- Have a family history of thyroid conditions
- Have an autoimmune condition such as coeliac infection or type 1 diabetes
Thyroid Stimulating Hormone (TSH)
Thyroid stimulating hormone (TSH), also known as thyrotropin, is a hormone produced by the pituitary gland of the brain. The release of TSH stimulates the thyroid gland to produce thyroxine (T4) and triiodothyronine (T3). These hormones regulate the body’s metabolism.
Free Thyroxine (FT4)
Free thyroxine (FT4) is the biologically active form of thyroxine, a hormone produced in the thyroid gland to regulate your metabolism. FT4 is not bound to proteins and is available for use by the tissues of the body. Raised FT4 levels can indicate an overactive thyroid (hyperthyroidism), low FT4 levels can indicate an under active thyroid (hypothyroidism).
Free Triiodothyronine (FT3)
Free triiodothyronine (FT3) is one of two major hormones produced by the thyroid gland. FT3 is more biologically active than thyroxine (T4) and is required to regulate metabolism. FT3 is produced directly by the thyroid gland, and through the conversion of T4 to T3 in other cells of the body.
Thyroglobulin Antibodies (TGAB)
TGAB is an antibody which can indicate thyroid damage caused by an autoimmune disorder.
Thyroid Peroxidase Antibodies (TPO/TPEX)
TPEX is an antibody which can indicate thyroid damage caused by an autoimmune disorder.
Thyroxine (T4) is one of two major hormones produced by the thyroid gland. It is required to regulate metabolism. T4 is found in two different forms, bound to proteins, or free (unbound) in the bloodstream. Protein bound T4 cannot enter the cells of the body for use in metabolism. Free thyroxine (FT4) is biologically active and readily available for use by the body.

Still have questions?
Here are some questions we usually get about LetsGetChecked. If you would like yours answered, please contact us.
The home thyroid antibody test is for anyone who has symptoms of hyperthyroidism, hypothyroidism, has a family history of thyroid infection, has an autoimmune disorder or takes performance enhancing substances.
Activating the test connects you to the unique alphanumeric barcode within your LetsGetChecked sample collection kit. The laboratory cannot process your sample if the test is not activated and linked to you. You should only activate your test when you are ready to take your sample.
Yes. LetsGetChecked has a team of doctors who will review your order and results and have created detailed result breakdowns for your testing journey.
Our nursing team is on standby throughout the testing process and, if your test results are abnormal, you will receive a call to discuss your results and next steps.
Please ensure that the sample is collected before 9am and returned immediately using the carrier method provided within the sample collection kit. It is not usually necessary to fast for this test, although sometimes not fasting can have a small impact on TSH levels. Talk to your healthcare provider about what is best for you. Each of our health tests includes a prepaid delivery envelope to return your samples to the laboratory.
Please do not collect or return samples on a Friday, Saturday or Sunday.
