Cervical Smear Tests Smear tests for women involve an examination of the cervix (neck of the womb) to check for changes which occur before cancer develops. This test can be performed by any of the doctors or practice nurse. We recommend that all women who are aged 25 to 50, whether sexually active or not, have a smear taken every three years. Those over 50 should have the test done every five years up to the age of 64. We normally notify abnormal results but please phone to check that your result has been received four weeks after it is done.
