FAQ
Is OHIP covered?
TSH is OHIP-covered with clinical indication. Free T3, T4, and thyroid antibodies may be covered with hypothyroidism symptoms or prior abnormal TSH. Your NP will optimize coverage.
What is a normal TSH?
The standard reference range is 0.4–4.0 mIU/L, though many functional medicine MDs target 1.0–2.5 for optimal thyroid health. Your NP will interpret in full clinical context.
What does anti-TPO positive mean?
Elevated anti-TPO indicates Hashimoto's thyroiditis — an autoimmune attack on the thyroid gland. Many people with positive antibodies have normal TSH initially but may develop hypothyroidism over time.
Do I need to fast?
Fasting is not required for thyroid tests. TSH is ideally drawn in the morning and before any thyroid medication for monitoring purposes.
