For a stable patient on levothyroxine,
TSH is usually rechecked 6â8 weeks after any dose change; once stable, every 6â12 months is generally adequate.
A TSH of 5.6 may need a small adjustment depending on symptoms, free T4, adherence and cardiac or bone risk, but do not change the dose without review.
Anti-TPO can help clarify autoimmune thyroiditis but usually does not need repeated testing.
Please consult or book on Practo with recent TSH/free T4 results and medication details.
