For most operations, you can donate once you have fully recovered and all wounds are healed.
Keyhole surgery, endoscopy, colonoscopy
If you have had an investigation or procedure using a flexible scope you will have to wait 120 days before donating.
If the investigation has been carried out with a rigid endoscope (e.g. colposcopies and most arthroscopies and proctoscopies) and you are well and not waiting for further tests or results you can donate.
For major procedures, you may have to wait at least 6 months before donating.
You will be unable to give blood if you have received, or think you have received a blood transfusion since 1980.
