Thyroid Panel-1 Test (T3/T4/TSH)

Report
The thyroid gland, an endocrine gland, produces these hormones under the stimulation of TSH (thyroid stimulating hormone). The Thyroid Panel-1 comprises a series of blood tests used to assess thyroid gland function and detect thyroid diseases by measuring the levels of thyroid hormones in the blood. These hormones, T3 and T4, are crucial for regulating metabolism and various energy-related functions in the body. The panel provides insights into whether the thyroid gland is functioning properly, indicating conditions like hyperthyroidism or hypothyroidism.
Reasons for Undergoing the Thyroid Function Test
The thyroid test checks levels of T3 (triiodothyronine), T4 (thyroxine), and TSH (thyroid-stimulating hormone) and is important for assessing your thyroid function. There are several reasons why you might need to take this test, including diagnosis, investigation, and screening for:
- Hyperthyroidism (an overactive thyroid) and hypothyroidism (an underactive thyroid)
- Symptoms may include nervousness, anxiety, sensitivity to heat, fatigue, changes in weight, sensitivity to cold, and constipation
- The effectiveness of treatment for thyroid disorders includes levothyroxine therapy for hypothyroidism and anti-thyroid medications for hyperthyroidism
- Individuals with a family history of thyroid disorders or those at a higher risk due to other medical conditions
List of Parameters Considered During the Thyroid Function Test
The thyroid test measures several key parameters to assess thyroid function:
- Thyroid-Stimulating Hormone (TSH): Produced by the pituitary gland, TSH stimulates the thyroid to produce thyroid hormones. High TSH levels usually indicate primary hypothyroidism, while low levels indicate hyperthyroidism or secondary hypothyroidism.
- Free Triiodothyronine (FT3): FT3 is an active form of thyroid hormone. High FT3 levels may indicate hyperthyroidism, especially in conditions like Graves’ disease, while low FT3 levels can indicate hypothyroidism.
- Free Thyroxine (FT4): FT4 is the primary form of thyroid hormone found in the blood. High FT4 levels can indicate hyperthyroidism, thyroiditis, excessive iodine intake, high protein levels, or too much thyroid medication. Low FT4 levels may suggest hypothyroidism, iodine deficiency, or a potential issue with the pituitary gland.

The thyroid panel primarily assesses thyroid gland function and is commonly employed in the following scenarios:
- Suspected hypothyroidism, characterized by symptoms such as fatigue, increased sensitivity to cold, constipation, dry skin, weight gain, muscle weakness, and facial puffiness.
- Suspected hyperthyroidism, presenting symptoms like unintentional weight loss, rapid heart rate, irregular heartbeat, palpitations, increased appetite, nervousness, and irritability.
- Monitoring thyroid patients to gauge the effectiveness of their treatment regimens.
Thyroid test measures thyroid stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3) levels in the blood.
A blood sample is required for this test. On the upper arm, a tourniquet (elastic band) is firmly fastened. A fist is then requested from the patient. This aids in the veins filling up with blood. Before inserting the needle, the skin is cleaned. A vacutainer is used to collect the blood sample. The blood sample is then sent to a laboratory for analysis.
Results of TSH in combination of T4 are often used to diagnose primary and secondary causes of hypothyroidism & hyperthyroidism.
- TSH high: T4 low (primary hypothyroidism), T4 high (secondary hyperthyroidism)
- TSH low: T4 low (secondary hypothyroidism), T4 high (primary hyperthyroidism)
There are no specific preparations required for the test. However, it is recommended that you consult with your healthcare provider before taking the test, as they may have specific instructions or recommendations based on your individual medical history and current health status.
