TESTING THE SURFACE FIXATION METHOD IN GESTATIONAL DIABETES MELLITUS

Introduction: To test the surface fixation method contrasting urine samples of women with GDM vs healthy pregnant women. Methods: This was a pilot descriptive study. Three groups were conformed: A) Pregnant women with GDM, B) Women with healthy pregnancies and C) Non-pregnant healthy women. The positiveness of the surface fixation method was contrasted with Odds Ratio. Results: 12 women with GDM, 14 with healthy pregnancies and 9 non-pregnant women were included in the study.The OR for a positive surface fixation test when contrasting GDM vs Healthy pregnancies was of 2.7 while the value when contrasting GDM vs Healthy pregnancies + Non pregnant women was of 3.2 without reaching significant statistical difference in any case. Conclusion: the surface fixation method used with urine samples, suggests the existence of a transient antigen-antibody reaction that contributes to the inefficient insulin secretion.
