Can birth control cause thyroid test anomalies?

In the past use of oral contraception could affect the tests used to check if someone’s thyroid was working.

However, the development of more modern tests eliminated this effect.

If you have a thyroid problem or are being investigated for a thyroid problem you should always tell your doctor what method of contraception you are using.

This is because it is important that your doctor has a complete picture of your current health and any medication you are taking.
