The International Society for Analytical Cytology, ISAC, has developed a flow cytometry standard (FCS) to permit data interchange, ISAC will soon replace FCS 2.0 with FCS 3.0. Unfortunately, the proposed FCS 3.0 is still fraught with problems, which are of sufficient magnitude as to warrant its early replacement. The most reasonable replacement is as a supplement to the digital imaging and communications in medicine, DICOM 3.0, standard. The recent digital microscopy extension of DICOM can be extended and modified to include flow cytometry data. DICOM includes: image graphics objects, specifications for describing: studies, reports, the acquisition of the data and the individuals involved, physician, patient, etc. Storing the present FCS data in a database, which has already been accomplished with the QC tracker software, will facilitate the transition of FCS to DICOM.
