Hi, I'm Rh- and DH is Rh+. We've had 3 children and they all are Rh+. With DC3 I decided to decline the anti-D injection, and whether I have more children in the future depends on if I've become sensitised to Rh+ blood or not. I'd like to know before I consider another baby in the future, is it possible to request a blood screening test on the NHS if I'm not pregnant or do I need to go private?
