Thyroid Bundle 2 combines three crucial tests: TSH, Free T3, and Free T4, providing a streamlined assessment of your thyroid function. This bundle focuses on the key hormones responsible for regulating metabolism and energy levels. By measuring both the stimulating hormone (TSH) and the thyroid hormones (Free T3 and Free T4), this test helps identify potential thyroid disorders like hypothyroidism or hyperthyroidism. Understanding your thyroid hormone levels is essential for maintaining overall health and wellness, making this bundle an excellent choice for anyone concerned about their thyroid function.

About This Test

Reason to Check It

"Women are five to eight times more likely than men to have thyroid problems. In fact, one woman in eight will develop a thyroid disorder during her lifetime. Two important hormones, triiodothyronine (T3) and thyroxine (T4) are produced by your thyroid gland in response to a hormone called TSH, which is produced in the brain.  Too much T3 and T4 can result in a condition known as hyperthyroidism and too little T3 and T4 can result in hypothyroidism. 

Symptoms of hyperthyroidism include fatigue, anxiety, sudden weight loss, rapid heartbeat, irritability, more frequent bowel movements, difficulty sleeping, sweating and tremors. 

Symptoms of hypothyroidism include tiredness, weight gain, constipation, depression, sleepiness, memory loss, decreased sex drive and more. 

Pregnant women with undiagnosed or inadequately treated hypothyroidism have an increased risk of miscarriage, preterm delivery, and severe developmental problems in their children.

Additionally, 15% of the population has trouble converting Free T4 (the inactive form of thyroid) to Free T3 (the active form).  Oftentimes the only way to pick this up is to measure both of these hormone levels in the bloodstream." - Dr. Alan Hopkins

Test Preparation

  • No special preparation is required before your sample collection.


Please Note: We recommend overnight fasting and an early morning blood draw for all tests, even if no special preparation is required. Remember, it is OK to drink plenty of water. Drinking water helps hydrate you and makes it easier for the phlebotomist to obtain your blood sample.
