Is it permissible for a fasting woman to undergo a "smear test" to take a sample from the cervix?
A fasting person's rapid test (nasal swab) and a cervical biopsy break the fast if they lead to ejaculation due to lust. However, merely taking the sample without lust does not break the fast. Delaying it until night is preferable.
