What to do with a woman with elevated risk of an anomaly
Make sure dates are accurate and retake FHx Try to get partner in to discuss also Inform of results Provide written and paper info on invasive testing - do not book yet. Encourage to take time but make sure she is aware of time frame limitations Refer to genetic counsellor or other trained counsellor w/in few days Explain screening vs diagnostic Explain diagnosis of Downs Provide option of TOP Consider referral to foetal diagnostic unit for counselling or support groups for more info on child w Downs Consider referral to paed.

Counsel a woman presenting with an abnormality on her Pap smear
This is a screening test not diagnostic that has found something that, if left a long time, might turn into a cancer. This is not a cancer Requires further Ix +/- minor surgery Majority of these changes resolve by themselves even high grade changes but we think on balance it's better to remove high grade changes and watch low grade ones unless they're persistent or there's something else going on LLETZ or cone biopsy w local or gen anaesthetic If trying for pregnancy wait until after treatment completed - treatment will take about 6/12 then wait for results of 6/12 check May cont taking the pill Consider Guardasil - six, eleven, sixteen and eighteen
