TSH Ultra-Sensitive

The TSH Ultra Sensitive Test is a blood test that measures the level of Thyroid Stimulating Hormone (TSH) with high sensitivity. It helps in detecting even minor changes in thyroid function, making it useful for early diagnosis of hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). Doctors commonly recommend this test to monitor thyroid disorders, assess treatment effectiveness, and screen individuals at risk.

Uses of the TSH Ultra Sensitive Test

• Detect early-stage thyroid disorders
• Diagnose hypothyroidism & hyperthyroidism
• Monitor thyroid hormone replacement therapy
• Evaluate unexplained fatigue, weight changes, or mood disorders
• Screen pregnant women (since thyroid imbalance can affect pregnancy & baby’s development)
• Support diagnosis in patients with goiter, infertility, or irregular menstrual cycles

• Adults: 0.4 – 4.0 mIU/L (may vary slightly by lab)
• Pregnant women: Lower reference range is often used (around 0.1 – 2.5 mIU/L in the first trimester)

3. Is fasting required for TSH Ultra Sensitive test?
No, fasting is not needed.

4. Can this test detect thyroid issues at an early stage?
Yes, it is highly sensitive and can detect subclinical thyroid disease even before symptoms appear.

• For people on thyroid medication: every 6–12 weeks initially, then every 6–12 months
• For general screening: as advised by a doctor, especially in women, elderly, or those with risk factors
