Waters receives FDA 510(k) clearance for BD OneFlow lymphoma diagnostic tests

Waters Corporation announced that its BD OneFlow LST and BD OneFlow B‑CLPD T1 flow cytometry tests have been cleared by the U.S. Food and Drug Administration under 510(k). The tests target B‑cell non‑Hodgkin lymphoma, including chronic lymphocytic leukemia, and are slated for U.S. commercial launch in spring 2027. Waters highlighted that the ready‑to‑use solution cuts manual steps and improves diagnostic consistency.

The clearance allows Waters to market the tests in the United States, opening a new revenue stream from standardized lymphoma diagnostics. Laboratories can expect faster turnaround and fewer errors, which may drive adoption and increase market share for Waters' diagnostics portfolio.
