What are T3, T4, and TSH? Understanding Your Thyroid Test Results

What does a thyroid function test involve?

A series of blood tests are used to measure how well your thyroid gland is working. Your thyroid is a small, fleshy gland located on the front of the neck, lower part. A central nervous system regulates several processes in the body, including metabolism, energy production, and mood.

Hypothyroidism is a condition that affects the thyroid gland. Comprise two major hormones are produced by the thyroid: triiodothyronine (T3) and thyroxin (T4). It is not uncommon for hypothyroidism to experience weight gain, feeling lethargic, and depression due to insufficient thyroid hormone production.

You may feel like you are high and euphoric if your thyroid gland produces too many hormones, also known as hypothyroidism, or be experiencing weight loss, anxiety, tremors, and feeling like you are crazy. The term hyperthyroidism refers to this condition.

Triiodothyronine Test (T3)

During this test, your blood is measured for triiodothyronine (T3) levels. The thyroid gland, located just below the throat, comprises two hormones, T3, which our body makes. One of the hormones we’re talking about is called thyroxin (T4). Both of these hormones work together to control the amount of energy your body uses. So, besides controlling your weight, body temperature, muscle strength, and nervous system, hormones also play an essential role in keeping you healthy. In its two forms, the T3 hormone can be divided into:

  • The T3 that is attached to the protein is bound
  • T3 is currently unattached from anything, so it’s completely free

Thyroxin Test T4

It is referred to as the T4 test or thyroxin test. The presence of high T4 levels is indicative of a hyperactive thyroid gland (hyperthyroidism). Anxiety, unplanned weight loss, tremors, diarrhea, and tremors are some of the symptoms. T4 is mainly bound to proteins in the body, which is why most of it stays there. Approximately 10% of T4 is free, and this can be referred to as free T4. Your body can readily utilize free T4 as it is readily available in this form. As part of the T4 test, it is sometimes also checked to see if the free T4 is standard or not.

TSH Test

TSH Test A blood sample is the best way to measure thyroid stimulation hormone (TSH) levels. As an “early warning system,” changes in TSH can occur before thyroid hormone levels in the body become dangerously high or low.

TSH levels above normally indicate inadequate thyroid hormone production (primary hypothyroidism). Thyroid hormone levels that are too high (hyperthyroidism) indicate a low TSH level. An abnormality in the pituitary gland may result in a low TSH (central hypothyroidism) if it cannot produce enough TSH to stimulate the thyroid. Usually, healthy individuals with an average TSH value have a properly functioning thyroid gland.

Follow-up

The doctor may order a thyroid uptake or an ultrasound test if your blood work suggests you haven’t been doing well with your thyroid gland. Tests such as these will determine whether or not there are any structural thyroid problems, if the thyroid is functioning correctly, or if there is any tumor present. It is recommended that your doctor test the tissue of your thyroid to look for cancer if these findings are confirmed.

The scan will result in a prescription of medication for you to help regulate the activity of your thyroid if the scan is normal. To ensure that the drug will be working, you will be followed up with additional thyroid function tests. If you are thinking of doing a thyroid test, then Pluspin can be proved the best one.
