Your thyroid is a powerful gland capable of regulating metabolism, heart rate, and body temperature. It can even impact your mental performance. 
However, if you’re one of the 20 million Americans who have a thyroid disorder, you may need to monitor your thyroid health.  That’s because thyroid disorders can cause several negative symptoms. 
Fortunately, checking your thyroid with an at-home thyroid test isn’t only possible—it can also be simple. To identify what you can do to keep your thyroid in check and avoid a future thyroid issue, follow our guide on three ways how to check your thyroid at home.
Thyroid disorders can show several symptoms—from fatigue and weight gain to heart palpitations and anxiety.  Many of these symptoms appear together, making it easier to detect a thyroid problem.
Let’s take a closer look at the symptoms associated with two of the most common thyroid disorders: hyperthyroidism and hypothyroidism.
Hyperthyroidism is a condition caused by the active thyroid’s excess production of thyroid hormones.  When an overactive thyroid gland occurs, you may feel and experience: 
If you’re experiencing any of these symptoms, you should see your healthcare provider as soon as possible. Knowing when and how to diagnose hyperthyroidism is essential in getting the appropriate treatment.
If an overabundance of thyroid hormones can cause hyperthyroidism, a hormone deficit can cause hypothyroidism. If you have hypothyroidism, you may feel and experience: 
Like hyperthyroidism symptoms, hypothyroidism symptoms can be serious if left untreated. Knowing how to test for hypothyroidism can help you spot it early to avoid serious risk factors.
Whether you’re experiencing hyperthyroidism, hypothyroidism, or another thyroid disorder, monitoring your symptoms is crucial. You should keep an accurate record of how you’re feeling—especially if your symptoms progress.
Before taking a thyroid blood test or other thyroid function tests, you may want to feel for lumps or nodules at the base of your neck. That’s because the thyroid is located close to your larynx and collarbone.  Lumps or nodules may be an indication that something is wrong with your thyroid. 
To check for a thyroid nodule or lump, you may need to tilt a mirror towards the base of your neck as you feel for any masses.
You may also want to drink a glass of water. If you notice pain or tenderness as you swallow, you could be experiencing thyroid disorder symptoms.  If you’re curious about when to worry about thyroid nodules, check with your healthcare provider for more information.
At-home lab tests can be accessible, convenient, and valuable tools when it comes to checking your thyroid or for potential thyroid dysfunction.
Most at-home thyroid tests work by measuring thyroid hormone levels in your blood. These hormones include: 
Some of the best at-home lab thyroid tests go one step farther by testing free T3 and T4. These thyroid function tests take into account the proteins that bind to these hormones. In doing so, Free T3 and T4 tests can provide a much more accurate picture of your thyroid hormone levels.
Although the specifics of each test may vary slightly by company, most tests follow a similar procedure:
Once the lab has your sample, they will measure your thyroid hormone levels and send you the test result. Some testing companies will even work with board-certified healthcare providers. These healthcare providers can provide you with further information based on your measurements.
