Furthermore, could taking the medication introduce variability into the lab results that are intended to provide a snapshot of thyroid hormone levels? As tests can indicate both hyperthyroidism and hypothyroidism, what considerations should individuals weigh before making a decision? Navigating these questions is essential for anyone seeking clarity on their thyroid health.
