Background: There are some antibodies which are present in healthy individuals without any former exposure to foreign antigens; they are known as natural autoantibodies (NAAbs). In recent years, it was shown that they probably contribute to the homeostasis of the whole body and might be present before beginning of some diseases. Thus, as new biomarkers, they are promising factors to diagnose diseases. Materials and Methods: In this study, we drew upon samples of 924 individuals (600 controls and 324 cases) with underlying diseases of anemia, polycythemia, leukocytosis, thrombocytopenia, thrombocytosis, and pancytopenia. For detection of NAAbs against red blood cell, plasma samples were incubated with their own red cell suspension in 4°C for 18 h. Then, positive samples were evaluated for antibody screening and titration. Results: Fifty-two (8.6%) controls and 58 (17.9%) cases showed positive reaction (Pv < 0.001). The prevalence of positive antibody screens among auto-positive controls was 53% and 100% among cases; moreover, strength of antibody screen reaction had a mean rank of 22.5 in controls and a mean rank of 38.5 in cases (Pv < 0.001). A significant relation was also observed between ABO blood group and prevalence of NAAbs in controls but not in cases (Pv < 0.05). Conclusion: The prevalence and potency of NAAbs increased along with hematological changes; moreover, the antibody reactions' pattern and titration showed significant differences between the two groups and these may be useful as biomarker for monitoring and prediction of some hematological diseases.
