We describe the engineering and product development of the chemiluminescent ZstatFlu®‐II Test kit for influenza diagnostics. The reaction vessel is a chemical implementation device with a polystyrene bottom chamber and a polypropylene top chamber that screw together. The patient's specimen is dispersed in a proprietary diluent and mixed inside the bottom chamber with the influenza viral neuraminidase‐specific substrate, 1,2‐dioxetane‐4,7‐dimethoxy‐Neu5Ac. Neuraminidase catalysis releases the dioxetane. The top chamber contains 40% NaOH and is sealed at the top with an ABS plastic plug‐crush pin assembly. The top chamber floor is 85% thinner at the centre, forming a frangible flap. An automated imaging device serves as an incubator for the chemical implementation devices and also facilitates the piercing of the flap by the crush pin. This action results in NaOH flushing into the bottom chamber, initiating chemiluminescence. The imaging device also exposes the Polaroid™ high‐speed detector film to chemiluminescence. At the end of exposure, the film is automatically processed and ejected. Chemiluminescence from an influenza virus‐positive specimen produces a ‘+’‐shaped white image, archiving the diagnostic outcome. The modular ZstatFlu®‐II test kit components are easily adaptable for the chemiluminescent detection of a wide range of analytes. Copyright © 2003 John Wiley & Sons, Ltd.
