The term "Rh Disease" is commonly used to refer to HDFN due to anti-D antibodies, and prior to the discovery of anti-Rh o (D) immune globulin, it was the most common type of HDFN. The disease ranges from mild to severe, and occurs in the second or subsequent pregnancies of Rh-D negative women when the biologic father is Rh-D positive.
Rh o (D) immune globulin (RhIG) is a medication used to prevent RhD isoimmunization in mothers who are RhD negative and to treat idiopathic thrombocytopenic purpura (ITP) in people who are Rh positive. [2] It is often given both during and following pregnancy. [2] It may also be used when RhD-negative people are given RhD-positive blood. [2]
Rh(D) status of an individual is normally described with a positive (+) or negative (−) suffix after the ABO type (e.g., someone who is A+ has the A antigen and Rh(D) antigen, whereas someone who is A− has the A antigen but lacks the Rh(D) antigen). The terms Rh factor, Rh positive, and Rh negative refer to the Rh(D

If a pregnant woman is known to have anti-D antibodies, the Rh blood type of a fetus can be tested by analysis of fetal DNA in maternal plasma to assess the risk to the fetus of Rh disease. [33] One of the major advances of twentieth century medicine was to prevent this disease by stopping the formation of Anti-D antibodies by D negative ...
Anti-C and anti-c can both show a negative DAT but still have a severely affected infant. [12] [13] An indirect coombs must also be run. In the case of anti-c, the woman should be checked around 28 weeks to see if she has developed anti-E as well. [citation needed]
By donating blood over 1,100 times, James Harrison helped develop Anti-D, a life-saving treatment for newborns at risk of Rhesus disease
[12] [17] Women who have a blood type of rhesus negative (Rh negative) may require Rho(D) immune globulin. [8] Pain medication may be beneficial. [12] Emotionally, afterwards, sadness, anxiety or guilt may occur. [3] [18] Emotional support may help with processing the loss. [12] Miscarriage is the most common complication of early pregnancy.
