What is a Thyroid Panel - IV( FT3, FT4, TSH) Test in Kolkata ?
What is Thyroid Panel - IV( FT3, FT4, TSH)?
This panel measures free T3, free T4, and TSH levels in the blood. Free T3 and free T4 are the active thyroid hormones that tissues use. TSH is produced by the pituitary gland and signals the thyroid to make more or less hormone. 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 Thyroid Panel - IV( FT3, FT4, TSH) measure?
Together these tests show how well the thyroid is working. They are important because thyroid hormones control metabolism, energy, body temperature, heart rate, and mood. Doctors use this panel to detect underactive or overactive thyroid conditions, to monitor thyroid treatment, and to decide if further tests or imaging are needed. TSH is the most sensitive marker , it rises before T4 falls in early hypothyroidism, and falls before T3/T4 rise in early hyperthyroidism. A normal TSH effectively rules out clinically significant dysfunction.
What symptoms suggest Thyroid Panel - IV( FT3, FT4, TSH) may be needed?
A doctor may order Thyroid Panel - IV( FT3, FT4, TSH) 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. In Kolkata, residents of Kalighat and Park Street commonly present for this test after noticing these symptoms during a routine or preventive consultation.
How is Thyroid Panel - IV( FT3, FT4, TSH) performed?
GetVisit home collection in Kalighat or Park Street, Kolkata: a certified phlebotomist arrives at your address at your chosen slot (available from 6:00 AM), brings all sterile single-use equipment, collects the sample, and dispatches it to the NABL-accredited lab. Your digital report is delivered to your GetVisit profile the same day for most standard tests.
How accurate is Thyroid Panel - IV( FT3, FT4, TSH)?
Rare causes of inaccurate results include: very high biotin supplementation (interferes with immunoassays), haemolysed samples from difficult venipuncture, or failure to fast when fasting was required. Following preparation instructions and using a trained phlebotomist minimises these risks.
Are there any risks to Thyroid Panel - IV( FT3, FT4, TSH)?
There are no significant medical risks beyond those of a standard blood draw. Vasovagal fainting (rare) is more likely if you are fasting, anxious, or dehydrated. Drink 2 to 3 glasses of water before the appointment, remain seated during the draw, and stay seated for 2 to 3 minutes afterwards. Inform the phlebotomist if you have fainted during previous draws.
Thyroid Panel - IV( FT3, FT4, TSH) Test Preparation in Kolkata
Fasting and dietary instructions:
No fasting required. Eat and drink normally before the appointment. Stay well hydrated , drink 2 to 3 glasses of water before the draw. Avoid alcohol and vigorous exercise for 12 hours before collection.
Medication guidance:
If you are on levothyroxine, do not take your morning dose before the blood draw. Collect the sample first, then take your medication , taking it beforehand temporarily elevates free T4 and can produce a misleadingly low TSH.
What to bring:
Bring your doctor's prescription or test requisition, a valid photo ID, and your corporate health insurance card if using cashless OPD. Wear short sleeves or clothing with sleeves that roll up easily.
Timing:
Morning slots are recommended for most blood tests. Most markers are most stable before meals and activity. GetVisit home collection in Kolkata is available from 6:00 AM, including in Ultadanga and Lake Gardens.

Why Take a Thyroid Panel - IV( FT3, FT4, TSH) Test in Kolkata ?
When does a doctor order Thyroid Panel - IV( FT3, FT4, TSH)?
Thyroid Panel - IV( FT3, FT4, TSH) is ordered when thyroid disease is clinically suspected or when monitoring a patient on levothyroxine therapy. Symptoms often overlap with depression, anaemia, or menopause , making a blood test essential to distinguish thyroid dysfunction from other causes.
Who should get Thyroid Panel - IV( FT3, FT4, TSH) done in Kolkata?
Autoimmune hypothyroidism is among the most commonly diagnosed endocrine conditions in West Bengal. Women in Kolkata aged 25 to 50 who experience fatigue, weight gain, or menstrual irregularities should prioritise thyroid testing , these symptoms are often misattributed to stress or anaemia. Clinicians order a thyroid panel (FT3, FT4, TSH) when patients have symptoms like fatigue, weight changes, heat or cold intolerance, palpitations, or mood shifts. It helps diagnose and monitor hypothyroidism, hyperthyroidism, and thyroiditis, and it evaluates response to thyroid medicines. Adults above 30 in Kolkata benefit from periodic health screening that includes Thyroid Panel - IV( FT3, FT4, TSH) as part of a broader preventive panel. Residents of Gariahat, Dum Dum, 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 Thyroid Panel - IV( FT3, FT4, TSH) help diagnose?
The conditions diagnosable through Thyroid Panel - IV( FT3, FT4, TSH) depend on the specific markers the test measures. Results either confirm a suspected diagnosis, support a clinical suspicion requiring further investigation, or effectively exclude the condition the test was screening for.
What do Thyroid Panel - IV( FT3, FT4, TSH) results mean?
Subclinical hypothyroidism: TSH mildly elevated (4–10 mIU/L), normal free T4. Your doctor decides on treatment based on symptoms, anti-TPO status, and cardiovascular risk. TSH above 10 mIU/L: overt hypothyroidism , treatment is universally recommended. During pregnancy, TSH should be below 2.5 mIU/L in the first trimester.
How often should Thyroid Panel - IV( FT3, FT4, TSH) be repeated?
For preventive screening with a normal baseline: annually for most adults above 35. For monitoring a known condition: at the interval your specialist recommends , typically every 3 to 6 months for active conditions and annually for stable, well-controlled ones.
