My guess is that this is residual fibrin. People and machines do not necessarily sample from the same place in the plasma tube. Try repeating the manual test taking plasma from the bottom, the middle and the top and see if there's a difference. Another tip is that if it is fibrin, you can fish it out from the top of the gel using a fine yellow Eppendorf tip (probably others too, but that's what I use) - but not the white Diamed tips - they aren't fine enough. I am presuming that these were all results that should have been negative. If they should have been positive, disregard what I say abaout fibrin

I, too, am making the assumption that the lady is of White ethnicity, from what you post, but it must be remembered that, although Ro is far more common amongst the Black population than the White, it is not unknown for White individuals to be Ro (about 2%), so it is possible that the baby has inherited the Dce haplotype from the father.
