Sirona Dx Oncocyst PD-L1

Sirona Dx has announced the launch of its Oncocyst PD-L1 assay. The tool uses IncellDx technology to detect and quantify abnormal bladder cells and immune cells from urine cytology specimens that express the immune-oncology marker PD-L1 using multi-parameter flow cytometry and bioinformatics. Sirona's algorithm uses aneuploidy/DNA content in cells from the bladder. Researchers can perform the high-throughput, non-subjective assay in less than three hours, the firm said.
