Thanks for posting your query at DoctorSpring.com
If you have already developed antibodies, there is no point in having a shot of Anti - D injection.
You should repeat the ICT ( Indirect Coombs Test ) before going for the shot.
Only if it is negative ( meaning that you have not yet developed antibodies ), you need the injection.
All the best
Please feel free to discuss further.
Patient replied :
Here the routine is not to do that I found out this morning. Can it cause any harm to the baby, or myself, if i take it and have developed antibodies?
It can do no harm.
It would mean a waste of a couple of thousand rupees, and that matters !
