Does taking a smear from the uterine cervix (to check for an early cancer) nullify fasting in Ramadan?

All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.

The tests related to taking a smear from the cervix do not nullify fasting.

The Islamic Fiqh Academy stated that the matters that do not invalidate fasting include the following:

- What goes into the vagina such as suppositories, lotions, vaginal speculum, or a finger for medical examination.

- Introducing an endoscope or IUD into the uterus.

Finally, taking the smear test that you mentioned in the question is permissible provided it meets the conditions mentioned in fatwa 118326.

Allaah knows best.
