The FT3, FT4, and TSH tests assess thyroid function, helping diagnose thyroid disorders like hypothyroidism and hyperthyroidism.
The FT3 (Free T3), FT4 (Free T4), and TSH (Thyroid-Stimulating Hormone) tests are commonly ordered together to assess thyroid function. These tests provide insights into the levels of thyroid hormones in the blood, which help regulate metabolism, energy levels, body temperature, and heart rate. Testing these markers is essential for diagnosing and managing thyroid disorders such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid).
1. FT3 (Free T3): Measures the level of triiodothyronine (T3), the active form of thyroid hormone. Free T3 refers to the unbound hormone available to cells and tissues. T3 plays a key role in metabolic regulation.
2. FT4 (Free T4): Measures thyroxine (T4), the main hormone produced by the thyroid gland. Free T4 is the unbound form, which the body can convert into T3. T4 levels help assess thyroid function, as T4 is often high in hyperthyroidism and low in hypothyroidism.
3. TSH (Thyroid-Stimulating Hormone): Produced by the pituitary gland, TSH signals the thyroid to produce T3 and T4. TSH levels are inversely related to thyroid hormone levels—higher TSH indicates potential hypothyroidism, while lower TSH suggests hyperthyroidism.
These tests help in:
1. Diagnosing thyroid disorders: Including hypothyroidism, hyperthyroidism, and thyroiditis.
2. Monitoring treatment: For patients on thyroid medications, these tests ensure optimal hormone levels.
3. Investigating symptoms: Symptoms like fatigue, weight changes, mood swings, and hair loss may be due to thyroid imbalance.
This panel may be recommended for individuals experiencing:
Fatigue, weight changes, or mood disturbances: Common symptoms of thyroid disorders.
Heart rate abnormalities: Such as palpitations or irregular heartbeats.
Neck swelling or goiter: An enlarged thyroid gland.
Menstrual irregularities or fertility issues: Thyroid hormones play a role in reproductive health.
It’s also useful for:
Pregnant women: Thyroid health is critical during pregnancy.
Individuals with a family history of thyroid disease: Genetic predisposition can increase risk.
Patients on thyroid medication: Regular monitoring ensures effective treatment.

Abnormal TSH may suggest an underactive or overactive thyroid, but FT3 and FT4 levels are also needed to understand the full picture.
Generally, no special preparation is required, but some providers may advise fasting. Let your provider know if you’re on any medications, as certain drugs can affect thyroid levels.
The test involves a simple blood draw, so you may feel mild discomfort from the needle prick.
People with thyroid conditions may need regular testing, while others might only need testing if symptoms or risk factors are present. Consult your healthcare provider.
