Methods Clinical, histological and flow cytometry data were collected and distributions summarised for 380 benign lymph node excisional biopsies. The cytological features along with flow cytometry are needed to diagnose T-NHL. A normal CD4/CD8 ratio is greater than 1.0, with CD4 lymphocytes ranging from 500 to 1200/mm 3 and CD8 lymphocytes ranging from 150 to 1000/mm 3. Of these, 53 patients had predominant musculoskeletal symptoms, while 20 patients had predominant neurologic symptoms. Results were shown by gating on the live cells that were determined by the Live/Dead Fixable Aqua Dead Cell Stain Kit.
