Hi I am rh- type b. Didn't know until I got pregnant and almost died but I always knew I was different. I've had lots of pschic experiences and it often drives people away from me. It's nice to know I'm not the only one. Although I don't know where my ancestors orignated from I have almost all of the characteristics of an rh neg person...but what does it all really mean?
If the parents are both neg and the child is there is rarely problems
If the mother is neg and the child neg, no issues
If the mother is neg and the child positive
it sets up an antigen response(allergic reaction) and basically the body attacks the invader...
additional pregnancies can cause major issues unless the mother has a Rhogam(gammaglobulin blah blah blah)injection within a set time frame following birth to avoid complications in additional PG
Blue bloods
Copper based more than + blooded people, metabolise O2 less effectively
Blue babies-from crossing blood lines(MIXING BLOOD,(+) and (-) and having stillborn or low O2
differing metabolism
low temp, low BP etc
other things alot of info out there about it
Quoting: ShadowDancerGood summary SD.
Quoting: Anonymous Coward 312241 Its only not entirely true ....
the mother will only generate antibodies if the blood of the fetus mixes with that of the mother, placentas do not transmit blood of the fetus to the mother nor vice versa.
Only when the watersack breaches or the placenta breaches there can be a mix of those .
Mother and fetus have two seperate vascular systems that operate completely independant from one and other. The farthest a fetus's blood goes while still inside the mother is to the placenta where it gets nutrients from the mother whos blood transports those nutrients to the placenta.
So unless you take a fall, the pregnancy was of high risk or the body of the mother being especially feeble/weak.
There is little to no chance at all that fetus and mothers blood mix inside the womb, only when an accident happens like taking a hard fall, drug abuse ..etc.
Rhogam is administered when the mother is suspected not fit enough to carry through the pregancy without complications.
And you CAN say you don't want the shot to be pre emptively administered these days ...
