Body fluids that contain low numbers of cells, such as CSF (cerebrospinal fluid) and vitreous biopsies (here collectively referred to as ‘small samples’), pose a diagnostic challenge in case of clinical suspicion of lymphoma. Despite its high specificity and sensitivity, the exact diagnostic value of the EuroFlow SST (small sample tube) labeling for small samples is greatly dependent on the number of cells that can be studied and the viability of these cells.

Cell viability can be increased by collection of the cells in tubes containing
