What is a FT3, FT4, TSH (ULTRASENSITIVE) Test in Surat ?
What is FT3, FT4, TSH (ULTRASENSITIVE)?
This panel measures free T3 and free T4, the active thyroid hormones, and an ultrasensitive TSH. Free T3 and free T4 show how much active hormone is available to body tissues. It is particularly relevant in India, where hypothyroidism and autoimmune thyroid disease are among the most prevalent endocrine disorders , especially in women aged 25 to 50.
What does FT3, FT4, TSH (ULTRASENSITIVE) measure?
Ultrasensitive TSH helps detect small changes in pituitary signals that control the thyroid. These tests are important for diagnosing hyperthyroidism and hypothyroidism. They also monitor treatment with thyroid medicine or after thyroid surgery. Doctors use the results to explain symptoms like tiredness, weight change, fast heart rate, or cold intolerance.
What symptoms suggest FT3, FT4, TSH (ULTRASENSITIVE) may be needed?
A doctor may recommend FT3, FT4, TSH (ULTRASENSITIVE) when a patient reports unexplained weight gain or loss, persistent fatigue, hair thinning or diffuse hair loss, cold or heat intolerance, constipation or frequent loose stools, low mood or anxiety, palpitations, and irregular or heavy menstrual periods. Sample collection for Surat is available at labs and at home across Varachha, Piplod, and surrounding neighbourhoods.
How is FT3, FT4, TSH (ULTRASENSITIVE) performed?
Collection is a routine blood draw. Using a single-use sterile needle, the phlebotomist takes a small sample from a vein in your arm; GetVisit's team in Varachha and Piplod, Surat then barcodes and transports it under controlled conditions to the NABL lab.
How accurate is FT3, FT4, TSH (ULTRASENSITIVE)?
Accuracy for FT3, FT4, TSH (ULTRASENSITIVE) depends partly on preparation: high-dose biotin (hair-and-nail supplements) can distort thyroid immunoassays, so stop it 48 hours beforehand. GetVisit's NABL labs serving Varachha and Piplod, Surat run calibrated analysers with quality control on every batch.
Are there any risks to FT3, FT4, TSH (ULTRASENSITIVE)?
A blood draw for FT3, FT4, TSH (ULTRASENSITIVE) is very safe. Occasionally there is minor bruising or light-headedness; sitting for a couple of minutes afterwards at the Varachha or Piplod, Surat collection point usually prevents this.

Why Take a FT3, FT4, TSH (ULTRASENSITIVE) Test in Surat ?
When does a doctor order FT3, FT4, TSH (ULTRASENSITIVE)?
FT3, FT4, TSH (ULTRASENSITIVE) is part of a thyroid function panel used to check symptoms like fatigue, weight change, palpitations, temperature sensitivity, or mood shifts. Doctors order it to diagnose or monitor hypothyroidism, hyperthyroidism, thyroiditis, medication effects, and following thyroid surgery.
Who should get FT3, FT4, TSH (ULTRASENSITIVE) done in Surat?
Autoimmune thyroid disease is increasingly diagnosed in Surat's urban women. Adults above 30 in Surat benefit from periodic health screening that includes FT3, FT4, TSH (ULTRASENSITIVE) as part of a broader preventive panel. Residents of Ghod Dod Road, Athwa, and across the city with chronic conditions, those on long-term medication, and individuals with a relevant family history should test at the frequency their specialist recommends.
What conditions can FT3, FT4, TSH (ULTRASENSITIVE) help diagnose?
Abnormal results can come from autoimmune disease, iodine issues, certain medicines, or pituitary disorders. A family history of thyroid disease makes testing more likely.
What do FT3, FT4, TSH (ULTRASENSITIVE) results mean?
TSH above 4.0 mIU/L with low free T4: hypothyroidism , levothyroxine replacement is started and TSH rechecked every 6–8 weeks until stable. TSH below 0.4 mIU/L with high free T3/T4: hyperthyroidism , requires antibody tests and thyroid scan. Elevated anti-TPO with normal TSH: autoimmune thyroid disease (Hashimoto's) , monitor annually as this often progresses to hypothyroidism over years.
How often should FT3, FT4, TSH (ULTRASENSITIVE) be repeated?
Adults with a normal result and no symptoms: every 2 to 3 years, or annually after age 35. Patients on levothyroxine: every 6 to 8 weeks after a dose change, then every 6 to 12 months once stable. Pregnant women and those planning pregnancy: as directed, since thyroid targets are tighter in pregnancy.
What happens after FT3, FT4, TSH (ULTRASENSITIVE) results are ready?
Once your results appear in your GetVisit profile, discuss them with your doctor or a GetVisit-verified specialist. Your doctor will interpret each value in the context of your full health history, current medications, and symptoms, and advise on the next step: lifestyle change, repeat testing, medication adjustment, or specialist referral. All GetVisit reports are stored permanently and can be shared with any doctor instantly.
