FT3, FT4, TSH (ULTRASENSITIVE), in Visakhapatnam

Medication guidance:

If you take levothyroxine, give the sample first and take your dose afterwards, since taking it earlier can briefly raise free T4 and give a misleadingly low TSH.

Diet and fasting:

This test can be done at any time of day with no fasting. Keep to your usual meals and medicines, and drink water normally.

When to book:

Choose a morning slot for the most consistent results. Same-day home collection is offered throughout Visakhapatnam, Kancharapalem and Madhurawada included.

What to carry:

Carry your test requisition, a government-issued ID, and any previous reports so results can be compared over time.

FT3 (Free T3), FT4 (Free T4), TSH (Ultrasensitive)

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 Visakhapatnam?

Hypothyroidism is among the more common endocrine diagnoses locally. Women aged 25 to 50 across MVP Colony, Seethammadhara, and Dwaraka Nagar with fatigue, weight change or menstrual irregularity should prioritise thyroid screening. Adults above 30 in Visakhapatnam benefit from periodic health screening that includes FT3, FT4, TSH (ULTRASENSITIVE) as part of a broader preventive panel. Residents of Kancharapalem, PM Palem, 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?

A high TSH with low free T4 confirms hypothyroidism; a low TSH with high T3/T4 confirms hyperthyroidism. Positive anti-TPO antibodies point to autoimmune (Hashimoto's or Graves') disease. Subclinical patterns, a mildly abnormal TSH with normal T4, help identify people who need monitoring before overt disease develops. 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.
