The antibodies detected in this study were, anti-D (63.8%), anti-D+C (13.7%), anti-C, anti-E, anti-M, anti-Le a , and anti-Leb (4.5% each). The M antigen is located on the red blood cell surface glycoprotein known as glycophorin A. Anti-M may be naturally occurring (i.e. 15% of UK population Rh D-, therefore 60% of Rh D- mothers will carry a Rh D+ baby . One woman reported repeated stillbirths due to anti-M [4]. The pathogenic role of anti-thyroglobulin antibody on pregnancy: evidence from an active immunization model in mice. If a pregnant woman has an IgG anti-M that reacts at 37°C, ongoing titration is required and the paternal partner should be tested for the M antigen. I had anti-e with my first pregnancy and all they did was take my blood every 2 weeks for a new titer level. Anti-D and anti-c levels should be measured every 4 weeks up to 28 weeks of gestation and then every 2 weeks until delivery. Anti-P 1 Antibody .

Infants of SLE mothers with anti-Ro/SSA and anti-La/SSB antibodies have an increased risk of neonatal lupus syndrome; thus, pregnant patients with SLE should be tested for these antibodies as part of their prenatal assessment. The anti-RhE antibody is quite common especially in the Rh genotype CDe/CDe; it usually only causes a mild hemolytic disease, but can cause a severe condition in the newborn. Anti-M and anti-N antibodies are naturally occurring, cold-reacting IgM-class antibodies. With my second pregnancy my antibody levels didn't rise at all and I had a healthy girl at 36 weeks.

If you are Rh Positive and pregnant, you can stop reading now, as Anti D is not for you. Anti-M can also cause delayed onset anemia [10]. Anti-M is an antibody directed to an antigen of the MNS blood group system. A sensitive ELISA test for anti-Ro/SSA antibodies is useful in the diagnosis of ANA-negative SLE. Though studies show that the anti-M antibody has been found in a high number of pregnant women, the chance of a newborn developing hemolytic disease is very rare. RED CELL ANTIBODIES DETECTED IN PREGNANCY. Anti-S. We report the detection of a unique antibody to an antigen of high incidence, the anti-Ata. After an affected pregnancy, IVIG and plasmapheresis can be done during pregnancy [6].

Anti-Ata is usually produced by an Ata (–) individual after alloimmunization by transfusion or during a pregnancy and is associated with immediate or delayed hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. Anti-TPO positive euthyroid females had a higher prevalence of infertility, anaemia as well as preterm delivery. Anti-M and anti-N are generally clinically insignificant. Keywords: Anti-Kpa antibody, Hemolytic disease of the fetus and newborn (HDFN), Direct antiglobulin test (DAt), Hydrops fetalis, Alloimmunization ***** Rossi KQ, Scrape S, Lang C, O’Shaughnessy R. Severe hemolytic disease of the fetus due to anti-Kpa antibody. During the course of the study there were 13 cases of CHB that were unrelated to our maternal sample population- 10 to well women and 2 to women with an autoimmune disease. Euthyroid means they have normal thyroid functioning based on their TSH (thyroid stimulating hormone) level, the most common measurement of thyroid function.

Among the antibodies of the MNS blood group system, anti S antibody is generally IgG antibody reacting at 37°C. Red blood cell antibodies (non-ABO antibodies) are rarely detected in the first trimester, with prevalence rates estimated at approximately 1% to 2%.
