The thyroid is a butterfly-shaped gland at the base of the neck. It helps regulate the production of hormones that affect sleep, metabolism, and other key functions.

Problems with the thyroid can cause a range of symptoms, including:

Because other health conditions can cause these symptoms, a doctor may not immediately order a thyroid test if a person only has one of these symptoms.

In this case, a person might consider using an at-home test to determine whether a thyroid issue could be causing their symptoms.

Common thyroid disorders

About 5 in 100 people in the United States have hypothyroidism, also known as an underactive thyroid. In this case, the glad produces too few hormones.

Other thyroid conditions include:

Learn more about common thyroid disorders here.

At-home thyroid tests typically measure several thyroid hormones, including:

  • TSH
  • T3
  • T4

Some tests also check for thyroid antibodies. The presence of these can indicate the autoimmune disease Hashimoto’s thyroiditis.

The results of the test help a person determine whether there is a need to see a doctor.

Using a testing kit involves taking a finger-prick blood sample, placing the sample in a plastic bag, and returning it to the company in the provided envelope.

Each testing kit has specific instructions, and it is essential to follow these carefully to ensure an accurate result.

Some testing companies also have a doctor review the person’s results. If a person prefers, the company may be able to send the results to the person’s regular doctor.

It is important to note that several things can interfere with thyroid test results, either by affecting the test itself or by affecting a person’s thyroid hormone levels.

Examples that affect a person’s thyroid hormone levels include:

  • pregnancy
  • underlying health conditions
  • older age
  • certain medications, such as opioids, androgens, and estrogen

Biotin supplements can affect the results of a thyroid test.

Why use an at-home test?

At-home testing offers several advantages. These include:

  • convenience
  • cost-effectiveness
  • quick results
  • confidentiality

Do private medical insurance plans cover the costs?

Most private health insurance companies do not cover the costs of at-home testing.

But some at-home test providers accept payments from FSAs or HRAs.

If a person’s symptoms persist, they should contact a healthcare professional.

Symptoms of hypothyroidism may include:

  • fatigue
  • extra sensitivity to cold temperatures
  • constipation
  • weight gain
  • irregular or heavy periods
  • depression
  • a slow heart rate
  • joint aches and pains
  • a puffy face

Symptoms of hyperthyroidism may include:

  • nervousness
  • weakness and fatigue
  • extra sensitivity to hot temperatures
  • problems sleeping
  • a hand tremor
  • diarrhea
  • weight loss

If symptoms indicate a thyroid disorder, but the result of an at-home test is negative, contact a doctor for advice.

Below are answers to some common questions about at-home thyroid tests.

Are at-home thyroid tests reliable?

Studies have not assessed the accuracy of these tests.

To help ensure accuracy, a person should carefully follow the testing kit’s instructions and discuss any positive result with a doctor, who can provide guidance and describe the treatment options available.

Do home thyroid tests work?

Thyroid tests can show whether a person has levels of thyroid hormones or antibodies that suggest a health problem.

The FDA considers home test kits to be helpful for detecting conditions in people without symptoms and useful for health monitoring in people who need to regularly adjust their treatment plans. However, the FDA does not describe the effectiveness or accuracy of thyroid tests.

It is important to discuss the results of a home test with a doctor. These tests should not replace regular checkups. If a person has symptoms of a thyroid disorder but their results are negative, they should still speak with a doctor.

What are early warning signs of thyroid problems?

Symptoms of thyroid issues often develop slowly. As a result, a person may not notice any changes for several years. Some symptoms of thyroid conditions can include:

  • weight gain or loss
  • sensitivity to cold
  • hair loss
  • anxiety or depression
  • heavier or irregular menstrual periods

Do I need to fast before a thyroid test?

Usually, a person does not need to fast before an at-home test. However, follow all the instructions that a company provides in its kit.

What happens if test results indicate a thyroid problem?

A person should contact their doctor if they receive a positive test result. The doctor may confirm the result with a blood test in their office or clinic.

Some companies offer follow-up consultations with healthcare professionals, who can answer questions and describe the next steps.

If a person receives a negative result but continues to experience concerning symptoms, they should contact a healthcare professional.

At-home thyroid tests can help people feel more in control of their health. These tests may also be more convenient than visiting a clinic, for example. A person can often access their results in a few days and review them with a doctor.

It is essential to discuss any positive result with a healthcare professional, and if necessary, develop a treatment plan.
