Normal fresh platelets are discoid, and platelets that have been stored become spherical. Discoid morphology correlates with normal viability and imparts to a platelet suspension a "streaming" appearance when agitated. We developed a device that quantitates the percent of discoid cells in a suspension by means of laser light scattering at low angles. It performs this assay within 3 minutes on platelets contained in a plastic blood bag. The ability of the device to quantitate discoid platelets was demonstrated in the following ways: (1) comparison of percentage discs calculated from light-scattering data with visually observed optical streaming; (2) correlation of percentage discs from light scattering with the percentage determined by phase microscopy; and (3) observation of changes during room temperature storage. Platelet suspensions containing extreme (dendritic and balloon) forms were examined, and we conclude that these forms do not significantly affect the light-scattering assay. The optical measurements were also used to accurately approximate the total platelet counts of the suspensions. This device may have a role in the evaluation of platelets for transfusion.
