The system is capable of determining at least a complete blood count (CBC), a ?ve-part White blood cell differential, and a reticu locyte count from a Whole blood sample. The system prefer ably uses a laser diode that emits a thin beam to illuminate cells in a How cell and a lensless optical detection system to measure one or more of axial light loss, loW-angle forward

ABSTRACT

angle scattered light, and time-of-?ight measurements pro duced by the cells. The lensless optical detection system contains no optical components, other than photoreactive elements, and does not include any moving parts. Finally, the system uses a unique system of consumable reagent tubes that act as reaction chambers, mixing chambers, and Waste chambers for the blood sample analyses. The consum able tubes incorporate reference particles, Which act as inter nal standards to ensure that the dilutions made during pro cessing of the samples have been carried out correctly, and to ensure that the instrument is Working properly. The present invention also relates to methods for using the system.
