# Thyroid Function Tests:
FT3, FT4, and TSH 🦋

Thyroid function tests measure the levels of FT3 (Free Triiodothyronine), FT4 (Free Thyroxine), and TSH (Thyroid-Stimulating Hormone) in your blood. These tests are essential for assessing how well your thyroid gland is functioning and diagnosing conditions like hypothyroidism, hyperthyroidism, and other thyroid disorders.

What Are FT3, FT4, and TSH? 🔍

- FT3 (Free Triiodothyronine): The active form of thyroid hormone that regulates your metabolism, energy levels, and overall cellular function.
- FT4 (Free Thyroxine): The primary hormone produced by the thyroid gland, which is later converted into FT3 in your body.
- TSH (Thyroid-Stimulating Hormone): A hormone released by the pituitary gland that controls the production of FT3 and FT4 by the thyroid gland.

These three markers work together to maintain a healthy metabolism and energy balance in your body. ⚖️

Why Are Thyroid Function Tests Important? 🤔

Doctors recommend these tests to:

- Diagnose Thyroid Disorders: Detect conditions like hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).
- Monitor Thyroid Treatments: Track the effectiveness of medications or therapies for thyroid disorders.
- Evaluate Symptoms: Investigate symptoms like fatigue, weight changes, mood swings, hair loss, or temperature sensitivity.
- Screen High-Risk Individuals: Ensure thyroid health in people with a family history of thyroid issues, autoimmune diseases, or during pregnancy.

What Can the Tests Reveal? 👀

TSH Levels:

- High TSH: Indicates hypothyroidism (underactive thyroid).
- Low TSH: Suggests hyperthyroidism (overactive thyroid).

FT4 and FT3 Levels:

- Low FT4/FT3: May confirm hypothyroidism, where the thyroid gland is not producing enough hormones.
- High FT4/FT3: Indicates hyperthyroidism, where the thyroid gland is producing too many hormones.

The combination of these tests provides a comprehensive overview of thyroid health, helping to pinpoint the cause of abnormal hormone levels.
