New lower-cost assay system equivalent to flow cytometry for accurate CD4+/CD8+ cell counts
...syCD4 and EasyCD8 assays represent good lower cost alternatives
to approved flow cytometry methods of CD4+ and CD8+ T cell enumeration. The Guava assays offer comparable accuracy and reproducibility to the flow cytometry-based method, but are much simpler and more affordable to use." Absolute CD4+ and CD8+ T cel...
