Thyroid Test
Our thyroid test will provide a broad picture of your hormone levels and thyroid health. Collect your sample from home and get online lab results in 2 to 5 days.
What does it measure?
Thyroid Stimulating Hormone (TSH),
Free Thyroxine (FT4) and
Free Triiodothyronine (FT3)
Collection Methods
Finger prick
The LetsGetChecked thyroid test will provide insights into your thyroid health by looking at thyroid stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (T3). TSH is produced by the pituitary gland in the brain and it controls the production of T3 and T4 from the thyroid gland.
Up to 6% of those with thyroid disease are unaware of their condition

Depression
Dry, coarse or thickened skin
Constipation
Hand tingling or pain (carpal tunnel syndrome)
Irregular period or low sex drive

Impaired memory
Hyperthyroidism symptoms
Hyperthyroidism (Overactive Thyroid) occurs when the thyroid gland produces an excessive level of thyroxine (T4) and triiodothyronine (T3).
Symptoms can include:
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

What’s measured
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.

Super easy, got my results the day the lab received the sample. I knew something wasn't right w/my thyroid & now I don't have to beg a dr to take the labs b/c I already have them.
Very fast delivery, easy to use and the response came back quickly. I share with my physician to help improve my thyroid prescription. Will definitely order again in the future.
...quick way to get peace of mind about my thyroid...nice to know I’m fine. All tests came back normal the very next day...
I would do it again! by using the thyroid kit I was finally able to show the doctor and that something wasn’t right because they kept refusing to run certain tests for me.
...I love the fact that I can get my thyroid checked regularly at a cheaper rate than going to a doctors office. Appreciate a call from a nurse...Excellent service! I would rate 10 stars if I could!
Extended thyroid test now I have proof to take to Dr...I did have phone call from company and missed it to discuss results, l am happy with test...
The Thyroid test was painless and very easy to do...The test included everything you need...was happy with the experience overall :)
...I was wanting extra thyroid testing done...The instructions were easy to follow, the sample was easy to collect. And I got my results FAST! I will recommend them to others.
I got the full thyroid panel done...lovely nurse Ann rang me to discuss my results and to go through what each one meant. She really took her time and did not rush me. Great overall experience.
