In fact, an error rate of 10 percent or more in the Rh factor was typical of the old blood-typing tests! So, Abby, your readers should rely on only the relatively recent blood-typing tests to determine their blood types. I discussed this discrepancy with my doctor, who informed me that, although accurate for blood type, tests performed during the `40s and `50s were often incorrect for the Rh factor. I had always carried a card, given to me by my mother, that stated my blood type was ``O Positive.`` My pediatrician had tested my blood when I was a child back in the early `50s, and that card was part of my medical file along with my immunization records.

However, D-negative individuals can produce IgG anti-D antibodies following a sensitizing event: possibly a fetomaternal transfusion of blood from a fetus in pregnancy or occasionally a blood transfusion with D positive RBCs. It is common for D-negative individuals not to have any anti-D IgG or IgM antibodies, because anti-D antibodies are not usually produced by sensitization against environmental substances. The most significant Rh antigen is the D antigen because it is the most likely to provoke an immune system response of the five main Rh antigens. Best Answer: The Rh system is the second most significant blood-group system in human-blood transfusion with currently 50 antigens.
