NCT05883189

Brief Summary

The study is aim to establish 95th and 99th percentile for healthy pregancy women for antiphospholipid antibodies(aPLs), such as aCL IgG/M/A, B2GP1 IgG/M/A, aPS/PT IgG/M. The outcome of the study is expected to aid Antiphospholipid syndrome patients diagnosis and managment. We also include some obstetirc Antiphospholipid syndrome(APS) patients to analysis the correlation between antiphospholipid antibodies and pregancy outcome, also want to know the prevalenc of aPLs, which can be guide for clinical application for APS diagnosis and treatment.
