Flow Cytometric Human Leukocyte Antigen-B27 Typing with Stored Samples for Batch Testing

摘要

BackgroundFlow cytometry (FC) HLA-B27 typing is still used extensively for the diagnosis of spondyloarthropathies. If patient blood samples are stored for a prolonged duration, this testing can be performed in a batch manner, and in-house cellular controls could easily be procured. In this study, we investigated various methods of storing patient blood samples.
