Do contraceptive pills show in a blood test?

Most blood tests will not show if you are taking the contraceptive pill.

The contraceptive pill contains hormones which prevent you from getting pregnant. If you are taking the combined pill the hormones it contains are oestrogen and progesterone.

If you are taking the “mini pill” it contains only progesterone. Most blood tests do not look for these hormones unless the doctor is particularly interested in checking your hormones.

However, it is important that if you are seeing your doctor for any health problem you tell them that you are on the pill. This is because your doctor needs to fully understand everything which may have an impact on your health and this includes taking the pill.

Anything you tell your doctor is completely confidential.
