Thyroid Function Panel

Combines thyroid function hormones and related antibodies.

For a combined assessment of thyroid function and autoimmune markers.

1. Check which tests are actually included in the panel.
2. Plan fasting and collection time around the strictest requirement of any component.
3. Write down your medicines and supplements in advance.
4. Additional note: tell your doctor if you take thyroid medicine or biotin. If results need to be compared, it is best to keep the collection time and its timing relative to your medicine consistent.

There is no single rule. Whether you need to fast, and for how long, depends on the purpose of the test and the laboratory method; check in advance.

A specific time is generally not required. If your doctor has set a different time, follow those instructions.

• Different preparation rules for each panel component
• Treatment and dietary supplements
• Different component methods and calculation conditions

Venous blood; depends on the components

Tests in the panel may need different tubes or different sample handling. Blood is drawn by a specialist; collection, storage and transport conditions are set by the method for each component.

Panel values should be interpreted together; a single abnormal value does not automatically mean a diagnosis. The meaning of a high or low result depends on age, symptoms, the method used and the reference interval.

If your result is outside the reference interval, you have symptoms, or your condition changes, contact your doctor. If symptoms are severe or develop quickly, seek emergency care.

Do not stop treatment on your own. Confirm the final test conditions with the laboratory.
