The Importance of Thyroid Profile Testing: What You Need to Know

Your body’s metabolism works well when your thyroid gland is functioning as it is supposed to. When there is an imbalance, thyroid profile tests will provide valuable insights.

The thyroid gland is responsible for controlling various body functions, including regulating metabolism. A thyroid test checks whether your thyroid gland is working well. If, for some reason, it is not functioning optimally, your body may or may not show signs. That is why you need to take regular thyroid profile tests. These tests check for the levels of TSH, T3, T4 and antibodies in your bloodstream. The results help the doctor to assess whether there is thyroid dysfunction or not.

What is the Thyroid Gland? How Does it Work?

The thyroid gland is a butterfly-shaped organ on the neck near your Adam’s apple. It secretes twotypes of hormones called T3 and T4, responsible for your body’s metabolism and energy. TSH is another hormone produced in the pituitary gland. It signals the pituitary gland to release T3 and 4T4 hormones. It also tells the pituitary gland to produce more or less hormones in case of overactive and underactive thyroid. This entire function is the reason why doctors ask for thyroid profile tests to see whether your thyroid is working correctly.

Which Tests Are Included in Thyroid Profile Test

A thyroid profile test, also known as a thyroid function test, is a series of blood tests that assess the functioning of your thyroid gland. It typically includes the following key thyroid-related tests:

TSH is used to measure your thyroid-stimulating hormone in the blood. This test is the first one that doctors see to figure out if your thyroid is working well. Your pituitary gland makes TSH. It signals your thyroid gland to produce thyroid hormones, T3 and T4.
T3 (or free T3) measures the triiodothyronine level in your blood.
T4 (or free T4) measures the level of thyroxine in your blood.
Thyroid antibody tests help your healthcare provider to see whether or not there are antibodies in your blood. The presence might indicate an autoimmune disorder like Graves’ disease or Hashimoto’s disease.

Thyroid Disorder Symptoms

Various symptoms occur when someone has a thyroid dysfunction. However, the symptoms are often similar to the signs of other medical conditions. This is why a thyroid test is best to check if you have a thyroid disorder.

The symptoms are divided into two parts. Each has a different set of symptoms.

Hypothyroidism occurs when there are fewer hormones. This condition shows symptoms such as the following:

Feeling tired
Weight gain
Heavy periods
Dry and thick hair
Deep voice
Intolerant to cold temperatures

Hyperthyroidism is when there are too many hormones in your bloodstream. This condition shows these symptoms:

Trouble sleeping
Losing weight
Enlarged goitre
Weakness in muscles
Irregular periods
Eye irritation

Importance of Thyroid Profile Testing

A thyroid profile test is essential because it can help diagnose and monitor thyroid disorders, such as:

Hypothyroidism: When the thyroid gland is producing insufficient thyroid hormones.
Hyperthyroidism: When the thyroid gland is producing too much thyroid hormone.
Thyroiditis: This condition occurs when the thyroid gland is inflamed.
Thyroid cancer: This is a rare type of cancer that starts in the thyroid gland.

Other reasons to do thyroid profile testing:

It helps people who are already diagnosed with a thyroid disorder, and their doctors, to monitor the treatment and overall health.
Women who are pregnant or planning to become pregnant may be asked to do thyroid profile tests. It is an important pre-pregnancy test as it can affect foetal development.
These tests help to diagnose thyroid disorders early on. This is because your body may not always show symptoms. Thyroid tests help to keep a check on your thyroid levels.

Who Should Get Tested

Thyroid disease can affect individuals of all ages – infants, women, teenagers, adults and older people. It can be present at birth or develop later.

People with a family history should get themselves tested regularly.
People with medical conditions such as lupus, diabetes, rheumatoid arthritis and more.
People who take medication that is high in iodine
People older than 60, especially women after menopause
People who have already been diagnosed with a thyroid disease or cancer.

How to prepare for your thyroid test

You don’t need to prepare for anything. You can eat and drink normally before your test. However, in some cases, your doctor might ask you to fast for 12 hours if they require additional blood reports.

What to expect during your test

There are two ways to do the test. You can either go to your local clinic or opt for an at-home thyroid test, in which a healthcare professional will visit your home to take your blood sample.

In both options, the provider will take your blood sample from your vein. The first step will be to sanitise the area and insert a sterile needle. The blood is then drawn and inserted into a tube to be sent to a lab for analysis. The process is completely painless and takes about 2-3 minutes.

What to expect after your thyroid test

Once you have your results back from the lab, your healthcare provider will discuss the findings with you. If you have abnormal reports, you might be recommended additional tests. Your doctor will also discuss the treatment plan, prescribe medications or advise lifestyle changes.

In conclusion, the thyroid profile test is vital to know how well your thyroid gland is performing. A thyroid imbalance can impair your body functions and affect your quality of life. Adding this test to your annual healthcare will help you catch thyroid disorders early. Subsequently, this will help in better and more effective treatment.
