What Does a Thyroid Panel-4 Measure?
The test evaluates the following key parameters:
- Free T4 (FT4 Test): Indicates the active thyroid hormone circulating in your blood, responsible for metabolism and energy regulation.
- TSH (Thyroid Stimulating Hormone): Produced by the pituitary gland, it signals your thyroid to release hormones.
Together, these values help your doctor:
- Detect thyroid dysfunction early.
- Determine whether you have hypothyroidism or hyperthyroidism.
- Monitor your response to thyroid treatment.
- Evaluate the cause of unexplained fatigue, weight gain or loss, and menstrual irregularities.
- Detect thyroid issues during pregnancy, where hormone balance is vital.

- Irregular menstrual cycles or fertility issues
- Sensitivity to cold or heat

Why is a Thyroid Panel-4 Done?
The test helps detect underactive or overactive thyroid gland function, guide treatment decisions, and monitor long-term hormone therapy.
Importance of a Thyroid Panel-4
Thyroid hormones affect nearly every organ in your body, so keeping them balanced is essential for good health. A Thyroid Panel-4 gives a comprehensive overview of your thyroid function, helping detect conditions like hypothyroidism and hyperthyroidism before symptoms worsen. It also supports ongoing treatment monitoring and helps tailor medication dosage for effective management.

How Should You Prepare for a Thyroid Panel-4?
To ensure accurate results, follow these simple preparation tips:
- No fasting required: You can eat and drink as usual before the test.
- Biotin caution: Avoid high-dose biotin supplements (more than 5 mg per day) for at least 8 hours before sample collection.
- Medication disclosure: Inform your doctor about any thyroid medications or supplements you take.

- Pregnancy disclosure: If you are pregnant, tell your doctor as hormone levels change naturally during pregnancy.
How Is a Thyroid Panel-4 Done? (Step-by-Step Procedure)
The procedure is simple and quick:
- Preparation: A band is tied around your upper arm to make veins visible.
- Cleaning: The puncture area is cleaned using an antiseptic.
- Sample Collection: About 3 ml of blood is drawn into a gel vacutainer.
- Completion: The needle is removed and a bandage is applied.
- Processing: The sample is analysed using ECLIA for precise measurement of thyroid hormones.
Conditions That May Affect Thyroid Panel-4 Accuracy
Certain factors can alter your thyroid test results:
- High-dose biotin: Supplements above 5 mg daily may interfere with thyroid assays.
- Medications: Amiodarone, steroids, beta blockers, and anti-epileptic drugs may affect thyroid hormone levels.
- Recent illness or surgery: Acute or chronic illnesses can cause temporary hormone fluctuations.
- Pregnancy: Hormone levels naturally vary by trimester.
- Stress or fasting: Extreme stress or prolonged fasting can transiently affect results.
