Essential Thyroid Function Panel

Whether you are checking your thyroid for the first time or monitoring prescribed thyroid medication, this panel provides three key markers: TSH, free T4, and free T3. Choose this test if you are experiencing fatigue, brain fog, constipation, temperature sensitivity, unexplained weight changes, hair thinning, low mood, or menstrual changes. It is also appropriate for routine follow-up if you take levothyroxine, Armour Thyroid, NP Thyroid, or liothyronine. Testing may be recommended after a dosage change. Do not stop, skip, or change medication without medical guidance. Biotin, including many hair, skin, and nail supplements, may interfere with thyroid results, so follow the laboratory’s preparation instructions. Two ways to order: receive your results directly, or add a $199 Lab Results Review with Dr. Tracy at Live In Vitality Wellness Center. We’ll review your results together, explain what they mean, and map out your next steps. Book at liveinvitality.net/book.
