At Home Thyroid Tests – PlushCare

The thyroid is an extremely important gland that regulates metabolism by producing two hormones (thyroxine and triiodothyronine). Approximately 10% of the US population has a thyroid disorder, but only half of those people are aware of it. Testing for thyroid disorders is relatively easy and can be done with various types of thyroid tests. Blood tests are the most common and can be done through the comforts of home.

What Can At Home Thyroid Tests Measure?

At home thyroid tests can measure concentrations of hormones and antibodies in your blood.

Thryoid hormones:

  • Thyroxine (T4) makes up 80% of the hormones produced by the thyroid.
  • Triiodothyronine (T3) makes up 20% of the hormones produced by the thyroid.
  • Thyroid stimulating hormone (TSH) is produced by the pituitary gland and regulates how much T4 and T3 the thyroid produces.

Thyroid hormones that are not bound to proteins are called “free.” Measurements of free T4 (fT4) and free T3 (fT3) are usually considered more accurate than measurements of total T4 and T3 counts.

Thyroid Antibodies:

Some thyroid disorders like Hashimoto’s thyroiditis involve the immune system attacking the thyroid. Testing for thyroid antibodies can help diagnose these types of health conditions.

Thyroid antibody tests include:

  • Thyroid peroxidase antibodies (TPO/TPEX)
  • Thyroglobulin antibodies (TGAB)

Blood Tests

At home blood tests are relatively quick and painless and can be completed in less than 10 minutes.

Steps involved with at home thyroid tests:

  1. Order your test. It will be shipped to your doorstep in a small package containing everything you need.
  2. Collect your blood sample. At home test kits come with instructions on how to use them. Most likely you will be instructed to wash your hands, clean the tip of a finger with an alcohol swab, prick your finger, and collect a few drops of blood. Depending on the company, you might put drops of blood onto paper or into a vial.
  3. Ship your sample to a lab. An at home thyroid test should come with prepaid packaging to return your sample in. There will also be a biohazard bag you put your sample into for safe transport.
  4. Review your results online. This should be available within a 2 to 5 days.
  5. Talk to a physician. If your results indicate a thyroid disorder, you should set up an appointment with a physician at PlushCare and determine a treatment plan that is right for you.

Basal Body Temperature

One of the symptoms of an underactive thyroid is low body temperature. By taking your body temperature one might be able to get an indication of thyroid activity. It is free, easy to do, and there is no harm in it, but it is not nearly as reliable and an official diagnosis will require blood tests.
