Do you feel unusually tired, cold all the time, or struggle with unexpected weight changes? These symptoms might be linked to your thyroid gland—a small but powerful organ in your neck that controls many aspects of your body’s metabolism. To understand your thyroid’s health, doctors often recommend a T3, T4, and TSH test. Let’s break it down for you.
What Are T3, T4, and TSH?
First, let’s understand the basics. The thyroid gland produces two key hormones—T3 (triiodothyronine) and T4 (thyroxine). These hormones regulate everything from your heart rate to body temperature.
But how does the thyroid know when to produce these hormones? That’s where TSH (thyroid-stimulating hormone) steps in. TSH is released by the pituitary gland and acts as the boss, telling your thyroid when to work harder or slow down.
If your T3, T4, or TSH levels are off, it can lead to conditions like hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).
Why Are These Tests Important?
Let me share a story. My friend Riya was feeling exhausted all the time, no matter how much she slept. She was also experiencing hair loss and mood swings. At first, she brushed it off, thinking it was due to stress. But after months of struggle, she finally visited a doctor.
Her doctor recommended a T3, T4, and TSH test to check her thyroid function. The results showed that her TSH levels were high, indicating hypothyroidism. With proper treatment, Riya was able to regain her energy and get back to living her best life.
This is why these tests are crucial. They help diagnose thyroid issues early, ensuring you can take action before the symptoms worsen.

Types of Thyroid Tests
Here’s a quick overview of the three main thyroid tests:
- TSH Test
- Measures the level of thyroid-stimulating hormone.
- High TSH indicates hypothyroidism, while low TSH suggests hyperthyroidism.
- T3 Test
- Measures triiodothyronine levels in your blood.
- Used to diagnose hyperthyroidism and assess thyroid function.
- T4 Test
- Measures thyroxine levels.
- Can help diagnose both hypothyroidism and hyperthyroidism.
Doctors often recommend all three tests together for a complete picture of your thyroid health.
Practical Tips Before Taking the Test
- Fast if necessary: Some labs may ask you to fast for accurate results. Confirm this with your doctor or lab.
- Schedule tests in the morning: Hormone levels can fluctuate throughout the day, so morning tests may provide more accurate readings.
- Discuss medications: Inform your doctor about any medications or supplements you’re taking, as they could impact the results.
What About the Cost?
The T3, T4, TSH test price can vary depending on where you get it done. On average, the price ranges from Rs 300 to Rs 800 in India, but some labs may offer discounted packages. It’s always a good idea to compare prices online or ask for recommendations to find a reliable and affordable lab near you.
Final Thoughts
Thyroid issues are more common than you might think, but the good news is that they’re manageable with early diagnosis and treatment. If you’re experiencing symptoms like fatigue, weight changes, or mood swings, don’t ignore them. A simple T3, T4, and TSH test could provide the answers you need.
