Thyroid Function Panel

A focused thyroid blood test measuring TSH and free T4 to evaluate thyroid gland function, screening for hypothyroidism, hyperthyroidism, and thyroid regulation disorders.

The Thyroid Function Panel at Vasmedic is a targeted blood test measuring two key thyroid markers: thyroid-stimulating hormone (TSH) and free thyroxine (fT4). Together, these markers provide a reliable first-line assessment of thyroid gland function and are the standard screening combination recommended by endocrinology guidelines worldwide. TSH is produced by the pituitary gland and acts as the primary regulator of thyroid hormone production. Elevated TSH with low fT4 indicates primary hypothyroidism (underactive thyroid), while suppressed TSH with elevated fT4 suggests hyperthyroidism (overactive thyroid). Subclinical thyroid disorders, where TSH is abnormal but fT4 remains within the reference range, are also detectable and clinically significant, particularly in women and older adults. Thyroid dysfunction is one of the most common endocrine disorders, affecting an estimated five to eight percent of the general population, with higher prevalence in women and increasing incidence with age. Symptoms can be subtle and nonspecific, including fatigue, weight changes, temperature sensitivity, mood disturbances, hair thinning, and menstrual irregularities, which is why routine screening is valuable even in the absence of obvious symptoms. The test requires a simple venous blood draw, typically performed in the morning. Fasting is not strictly required for thyroid markers, but if the panel is being combined with other blood work (such as glucose or lipids), the clinic may recommend a morning fasting appointment. Results are typically available within one to two business days. At 499 CZK (approximately 20 EUR), this is an accessible screening test that can be ordered as a standalone check or added to any of the clinic's broader health check packages. If results indicate thyroid dysfunction, the clinic's endocrinology department can provide immediate specialist follow-up, including extended thyroid panels (T3, anti-TPO, anti-TG antibodies), thyroid ultrasound, and treatment planning. The low cost makes it a practical addition for medical tourism visitors who want to screen for thyroid issues during their Prague visit.
