The short explanation
Family history matters most for close blood relatives. Your daughter shares your genes, so her chance of a thyroid condition is higher than average, particularly autoimmune thyroid disease, which is more common in women. Your husband is not a blood relative of your family, so your history does not change his risk, although he may have his own family history. Testing people with no symptoms is not always necessary, but a TSH test for your daughter is reasonable, especially if she has any symptoms or plans a pregnancy.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Symptoms worth noticing include tiredness, weight change, irregular or heavy periods, hair changes, feeling too hot or too cold, a racing heart, or a swelling in the neck.
- For your daughter, the decision about testing is hers as an adult; you can share the family history and encourage her to mention it to her doctor.
- If the first test is normal, repeating it is usually guided by symptoms or life events such as pregnancy.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell you whether anyone in your family will develop a thyroid condition. Tests and a doctor's assessment are needed.
Questions for your clinician
