Thyroid
Thyroid blood tests in women
TSH, Free T4/T3, and antibodies in context.
Thyroid patterns can shape cycle quality, fertility outcomes, metabolic symptoms, and perimenopausal experience. Decode helps you read thyroid-related tests with female-specific context.
Core thyroid panel
- TSH: pituitary signal, often first-line but not always sufficient alone.
- Free T4 / Free T3: active hormone context for symptom correlation.
- Anti-TPO / Anti-Tg: autoimmune thyroid context (e.g., Hashimoto-pattern risk).
When context matters most
Interpretation changes by life stage: preconception, pregnancy/postpartum, and perimenopause each alter symptom overlap and treatment relevance.
Educational context only
