Does anyone know?

A friend of my mum?s has a daughter who has recently had a baby girl. The baby has jaundice and is currently under the UV lamp in the Scbu. The doctors have told her that there is a problem with blood type and that because the baby is type A negative, and the mum is o negative, the baby will have to have blood tests for the foreseeable future, the pediatricians haven't said any more than that. Obviously she is very concerned about this and my mum asked if I could do some surfing about it. I?ve been looking this up on the net and can only find info that relates to there being problems if a baby is positive and mother is negative, but she?s adamant that the baby is negative as well just a different blood group. Does anyone know anything about this and what the implications are?

hi wannabe, sounds like baby has bloodgroup incompatibility (you can google for ABO incompatibility, and jaundice, which i did). I found this:
baby is bloodgroup A, so has typeA surface antigens, mum is bloodgroup O, so has no suface antigens and antibodies against typeA and typeB antigens. This is what causes the jaundice. Mum's antiA antibodies attack baby's red blood cells causing a sudden buildup of bilirubin in the baby's blood. It is good that the baby is having phototherapy (UV lamp), as this will keep bilirubin down (I think thats why they want to do the bloodtests). If this gets too high baby would risk neurological damage (e.g. deafness). Most babies are fine with treatment though, so dont worry too much!
