Thanks dillionmommy1228, I was called in earlier for a scan( il only be 11 weeks then)and was told by my hospital I'd need to go their for scans and blood tests every month...but is there anything I can do to stop the antigen rising??? :-/
Samples on patients who have developed significant red blood cell antibodies may be required more often than usual, the frequency of which will be indicated on the antenatal report. The samples are required to monitor the strength (titre) of the antibody(ies) concerned and to identify pregnancies which may be at risk from Haemolytic Disease of the Newborn (HDN). They also monitor the possible formation of additional allo-antibodies during the pregnancy. Patients who have developed red cell antibodies should be referred to an obstetrician.The current guidelines state that women with anti-c, D, K or K related antibodies require a titre check every 4 weeks until the 28th week of pregnancy and thereafter every 2 weeks until delivery. Other specificities commonly implicated as causing HDN include anti-C, E, Fya & Jka though there are many rarer antibodies.Anti-Lea, Leb, N, Lua, P1, H and A1 are not considered to be clinically significant as regards HDN.In some instances, a paternal sample may be requested. This is usually to determine the fathers phenotype and predict the likelihood of the foetus carrying the relevant red cell antigen, thus indicating whether the possibility of HDN exists.The red blood cell membrane contains numerous antigenic molecules which may induce the production of plasma antibodies. Currently there are more than 600 known red cell antigens. Immunisation is caused by exposure to 'foreign' red cells via pregnancy or transfusion though some plasma antibodies are naturally occurring.
What is it? Ive never heard of it before?
