Description
The third-generation TSH test is a highly sensitive and reliable blood test used to evaluate thyroid function. It is considered the most effective screening tool for detecting primary hypothyroidism and identifying subtle thyroid imbalances.
Why It’s Important:
- Greater sensitivity than older TSH tests—can detect very low hormone levels
- Ideal for identifying early or subclinical thyroid disorders
- Helps rule out overt hyperthyroidism in patients with borderline TSH levels
Clinical Uses:
- Screen for primary hypothyroidism
- Assess subclinical hyperthyroidism
- Monitor thyroid function in individuals with known thyroid disease or those on hormone therapy
Fasting not required.
This test offers a precise snapshot of your thyroid’s performance and is essential for early diagnosis and ongoing management.
