Essential functions of the body, like energy production, body temperature, heart rate, and growth, are regulated by the thyroid gland. A Thyroid Function Test is a series of blood tests that measure whether the thyroid gland is functioning well or not.
The profile includes Serum Free T3 (FT3), the biologically active form of thyroid hormone that helps regulate the body's metabolism and energy usage. Serum Free T4 (FT4) measures the free, unbound thyroxine available for use by the body's tissues and provides important information about thyroid hormone production. Serum TSH (Ultrasensitive) is produced by the pituitary gland and is considered the most sensitive marker for assessing thyroid function.
If anybody is experiencing vague symptoms like unexplained weight gain or weight loss, fatigue, or hair loss, they will benefit greatly from a free thyroid function test, as this test can reveal important things about the functioning of the thyroid gland by measuring important parameters.
This test can help diagnose a variety of conditions. When diseases are detected at the earliest stage, a swift and effective treatment plan can be initiated by doctors. This helps support overall health enhancement for patients and significantly improves a person's chance of recovery. Regular health screenings and preventive measures are important to diagnose conditions affecting the thyroid region.

रक्त का नमूना देने से पहले पानी पी सकते हैं।
डॉक्टर की सलाह के बिना अपनी नियमित दवाइयाँ बंद न करें। यदि आप थायरॉयड की दवा लेते हैं, तो डॉक्टर से पूछें कि दवा जांच से पहले लेनी है या बाद में।
यदि आप थायरॉयड की दवा, बायोटिन सप्लीमेंट, स्टेरॉयड या हार्मोन संबंधी दवाइयाँ ले रहे हैं, तो इसकी जानकारी स्वास्थ्यकर्मी को अवश्य दें, क्योंकि इससे जांच के परिणाम प्रभावित हो सकते हैं।
डॉक्टर का रेफरल तथा अपनी पुरानी थायरॉयड जांच रिपोर्ट साथ लेकर आएं।
यदि आप गर्भवती हैं, गर्भधारण की योजना बना रही हैं, या हाल ही में थायरॉयड की सर्जरी या रेडियोआयोडीन उपचार कराया है, तो इसकी जानकारी अवश्य दें।
रक्त का नमूना आसानी से लेने के लिए ऐसे कपड़े पहनें जिनकी आस्तीनें आसानी से ऊपर की जा सकें।

The healthcare professional verifies your details and explains the blood collection procedure.
A vein, usually in the arm, is cleaned with an antiseptic solution.
A sterile needle is used to collect a small blood sample into the required collection tubes.
The blood sample is analysed for Serum Free T3 (FT3), Serum Free T4 (FT4), and Serum TSH (Ultrasensitive) to evaluate thyroid gland function.
After the sample is collected, gentle pressure is applied to the puncture site, and a small bandage is placed.
The procedure is quick, safe, and usually completed within 5–10 minutes.
Reports are generally available within 24 hours*.
