Schilddruesen-Check -- Thyroid Panel

Core thyroid function panel measuring TSH, free T3, and free T4 -- the three markers needed to assess the hypothalamic-pituitary-thyroid axis. Screens for both hypothyroidism and hyperthyroidism. At EUR 61.88 under GOAe 1.0x rates including blood draw and outpatient fees, a cost-effective first-line thyroid assessment without referral.

This three-marker thyroid panel provides a complete functional assessment of thyroid hormone production and regulation. TSH (thyroid-stimulating hormone) is secreted by the anterior pituitary and is the single most sensitive marker for primary thyroid dysfunction. Elevated TSH indicates hypothyroidism -- the thyroid is underperforming and the pituitary compensates with increased stimulation. Suppressed TSH indicates hyperthyroidism -- excess thyroid hormone feeds back to suppress pituitary TSH secretion. Free T4 (thyroxine) is the predominant secretory product of the thyroid gland and serves as a prohormone. It is converted to the biologically more active free T3 (triiodothyronine) in peripheral tissues by deiodinase enzymes. Measuring both free hormones distinguishes between different patterns of thyroid dysfunction. Isolated T3 thyrotoxicosis (elevated T3 with normal T4) occurs in early Graves disease and toxic nodular goitre. Conversely, low T3 with normal T4 and TSH -- the low-T3 syndrome or euthyroid sick syndrome -- is seen in acute illness, caloric restriction, and severe stress. Subclinical thyroid disease (abnormal TSH with normal free hormones) is found in 4-10% of the general population. Subclinical hypothyroidism is particularly prevalent in women over 40 and in iodine-sufficient populations. Symptoms are often non-specific -- fatigue, weight changes, cold intolerance, dry skin, constipation, mood disturbance, hair thinning -- which is why biochemical testing is essential. Hamburg sits in a region historically considered mildly iodine-deficient, although widespread iodised salt use has improved population iodine status. Thyroid nodules and goitre remain more prevalent in northern Germany than in countries with longer histories of iodine supplementation. The GOAe 1.0x price for this panel is EUR 61.88 -- TSH at EUR 16.76, free T3 at EUR 16.76, and free T4 at EUR 16.76, plus the EUR 4.20 blood draw fee and EUR 7.40 outpatient consultation fee. At the standard 2.3x GOAe multiplier used by most German physicians, the same three assays would cost roughly EUR 120-140 before consultation fees.
