Abstract
INTRODUCTION: Anti-cardiolipin and β2-glycoprotein I antibodies represent important diagnostic parameters in routine hematology. In this study, five different automated, semi-automated, and manual immunoassays detecting IgG/IgM anti-cardiolipin and anti-β2 -glycoprotein I antibodies were tested.
METHODS: A total of 162 samples from women with a history of miscarriage were recruited from 110 different G&O outpatient centers in Germany.
RESULTS: For both anti-cardiolipin and anti-β2 -glycoprotein I antibodies, considerable differences in the percentage of positive results were seen between all five methods, and itemization of all positive test results revealed a poor accordance. These findings were confirmed by Cohen's kappa coefficients.
CONCLUSION: Our study revealed a moderate to poor accordance between five different test systems for anti-cardiolipin and anti-β2 -glycoprotein I antibodies. Such deviations may result in clinical misinterpretation of data and may lead to wrong therapeutic consequences. Therefore, further standardization of all tests for anti-phospholipid antibodies should be achieved.
