Six-marker extended thyroid assessment — TSH, free T3, free T4 plus three autoimmune antibodies (anti-TPO, anti-TG, anti-TSHR). Identifies Hashimoto thyroiditis, Graves disease, and subclinical dysfunction at their earliest biochemical stage. At 249 PLN (~58 EUR) with blood draw included — roughly half the cost of equivalent testing in Germany or Austria.

This panel delivers the most thorough thyroid evaluation available in a standard commercial package, pairing functional hormone assessment with a complete autoimmune antibody profile. TSH remains the most sensitive single indicator of thyroid dysfunction. Free T3 and free T4 measure the biologically active, protein-unbound hormone fractions — together they differentiate patterns such as isolated T3 thyrotoxicosis (common in early Graves disease) from standard T4-predominant hyperthyroidism. The three antibody markers transform this panel from a functional screen into a diagnostic investigation. Anti-TPO antibodies target thyroid peroxidase and are positive in roughly 90% of Hashimoto thyroiditis cases. Anti-TG antibodies add sensitivity for the subset of Hashimoto patients who are anti-TPO negative. Anti-TSHR (TRAb) antibodies are pathognomonic for Graves disease — they bind and stimulate the TSH receptor, driving autonomous thyroid hormone production. Including all three antibodies distinguishes this panel from competitors that offer only one or two. The clinical importance of autoimmune screening lies in early detection. Elevated antibodies frequently precede overt thyroid dysfunction by 5-10 years. A patient with normal TSH but high anti-TPO has a 2-4% annual risk of progressing to hypothyroidism — information that enables proactive monitoring rather than reactive diagnosis after prolonged symptoms. Hashimoto thyroiditis is the most common autoimmune disease globally, with a female-to-male ratio near 10:1. It clusters with other autoimmune conditions including type 1 diabetes, coeliac disease, and vitiligo. Family history is a strong predictor. Post-partum thyroiditis affects 5-10% of women and often goes unrecognised. At 249 PLN with blood draw included, comprehensive autoimmune thyroid assessment becomes accessible for proactive screening. Austrian and German private labs charge 150-300 EUR for an equivalent six-marker panel, making Krakow — with its direct flight connections to Vienna, Munich, and Berlin — a practical destination for combining tourism with thyroid evaluation.

Free T3 (fT3)
Free T4 (fT4)

Panel Categories

Thyroid Panel

Biomarkers Tested

8
Free T3 (Triiodothyronine) pg/mL

The active form of thyroid hormone responsible for regulating metabolism, energy, and body temperature. Free T3 is converted from T4 in tissues and is three to four times more potent than T4.

Free T4 (Thyroxine) ng/dL

The unbound, active form of the main thyroid hormone T4. Free T4 directly reflects thyroid gland output and is used alongside TSH to diagnose and monitor thyroid disorders.

FT3 pg/mL

Free triiodothyronine; high levels indicate hyperthyroidism, low levels hypothyroidism.

FT4 ng/dL

Free thyroxine; high levels indicate hyperthyroidism, low levels hypothyroidism.

Globulin g/dL

A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.

Reverse T3 (rT3) ng/dL

An inactive form of T3 produced when the body converts T4. Elevated reverse T3 can occur during illness, stress, or caloric restriction and may indicate impaired thyroid hormone activation despite normal TSH levels.

Thyroid Peroxidase Antibodies (TPO) IU/mL

Antibodies against thyroid peroxidase, an enzyme essential for thyroid hormone production. Positive TPO antibodies indicate autoimmune thyroid disease, most commonly Hashimoto's thyroiditis, even before symptoms or TSH changes appear.

TSH (Thyroid-Stimulating Hormone) mIU/L

The primary screening test for thyroid function. TSH is produced by the pituitary gland to regulate thyroid hormone production. High TSH indicates an underactive thyroid (hypothyroidism), while low TSH suggests an overactive thyroid (hyperthyroidism).
