What Medical Tests Are Done for Thyroid Disease?


Whatever the cause of the disease, it can be detected through accurate medical test reports. And, we, the best medical testing laboratory in Punjab, are always here to provide accurate diagnosis reports. 

Thyroid disease affects millions of people. When the thyroid gland does not produce enough or too many hormones, it can lead to a range of symptoms including fatigue, weight gain, and difficulty concentrating. A variety of tests are used in diagnosing and monitoring thyroid disease.

In this blog post, we will discuss these various medical tests used for thyroid diseases and their implications. We will also look at how they can help you manage your condition more effectively.

How Thyroid Gets Detected?

The thyroid gland is located in the front of the neck and produces hormones that regulate metabolism. Thyroid disease can cause a variety of symptoms, including weight gain or loss, fatigue, mood swings, and difficulty concentrating. A simple blood test can detect most thyroid disorders.

Blood Tests

There are several blood tests that can be done to diagnose thyroid disease. The most common is the TSH test. TSH stands for a thyroid-stimulating hormone test. This test measures how much TSH is in your blood. TSH is made by the pituitary gland and tells the thyroid gland how much thyroid hormone to make. If the thyroid gland is not making enough hormone, the pituitary gland will make more TSH in an attempt to stimulate the thyroid gland to make more hormone.

Other blood tests that may be done include:

Free T4 (FT4) – FT4 measures the amount of thyroxine (T4), which is the main hormone produced by the thyroid gland, in your blood.

Free T3 (FT3) – FT3 measures the amount of triiodothyronine (T3), which is another hormone produced by the thyroid gland, in your blood.

Thyroid antibodies – These tests measure levels of antibodies in your blood that attack and damage the thyroid gland.

Imaging Studies

Imaging studies are used to evaluate the structure and function of the thyroid gland. Thyroid ultrasound is the most common imaging study used to assess the thyroid gland. It is a noninvasive test that does not require radiation exposure. This test can be used to measure the size of the thyroid gland, determine if there are any nodules present, and assess the blood flow to the gland.

Other imaging modalities that may be used include computed tomography (CT) scan and magnetic resonance imaging (MRI). These tests are more expensive and are not routinely used in the evaluation of thyroid disease. Radioactive iodine uptake (RAI) scanning was previously used for diagnostic purposes but has largely been replaced by ultrasound and other imaging modalities.


In a biopsy, a small sample of tissue is removed from the body for examination. The sample is then examined under a microscope to look for abnormal cells.

There are two types of biopsies that can be done for thyroid disease: fine needle aspiration (FNA) and surgical biopsy. FNA is the most common type of biopsy and is done using a thin needle to remove a small sample of tissue from the thyroid gland. This procedure is usually performed in an outpatient setting and does not require anesthesia.

A surgical biopsy is less common but may be necessary if the results of an FNA are inconclusive or if there are suspicious areas on the thyroid that cannot be seen with an ultrasound. In this procedure, a larger piece of tissue is removed through an incision in the neck. This type of biopsy requires anesthesia and is usually performed in an operating room setting.

Thyroid Hormone Levels

Thyroid hormone levels are one of the most important pieces of information used to diagnose and treat the thyroid disease. The thyroid gland produces two main hormones, thyroxine (T4) and triiodothyronine (T3), which play vital roles in regulating metabolism. T4 is inactive but can be converted to the active form T3 in the body. T3 is three to four times more potent than T4 and is responsible for most of the biological effects of thyroid hormone.

Blood tests are the most common way to measure thyroid hormone levels. The most common test used to assess thyroid function is the thyroid stimulating hormone (TSH) test. TSH is produced by the pituitary gland in response to signals from the hypothalamus, and it regulates the production of T3 and T4 by the thyroid gland. A high TSH level indicates that the thyroid gland is not producing enough hormone, while a low level suggests that too much hormone is being produced.

Other blood tests that can be used to measure thyroid hormone levels include free thyroxine (FT4) and free triiodothyronine (FT3) tests. These tests measure the amount of unbound or “free” Thyroid hormones in circulation. Free thyroxine (FT4) is considered the best overall indicator of Thyroid function because it reflects both pituitary and Thyroid gland function, while free triiodothyronine (FT3) provides a more direct measure

Antibodies against Thyroid Peroxidase

The Thyroid gland produces an enzyme called Thyroid peroxidase. Antibodies against thyroid peroxidase can interfere with the function of this enzyme and may be associated with autoimmune thyroid disease.
