&&Lucira Covid -19 Check-It Test Kit for at home use is a single use test kit purposed to detect the novel coronavirus SARS-CoV-2 that causes Covid-19. The Covid test kits have two main components, the Sample Vial and the Test Unit. The Sample Vial is a single use, disposable unit containing an elution buffer to release and lyse virions from a nasal swab sample. It comprises of an injection molded plastic tube which contains elution buffer, a bottom foil seal and a peelable top foil. The tube includes an integrated lip cap with a venting membrane.&&&&The Test Unit is composed of individual components including the following: 1) Lyophilized pellets that act as chemical reagents and which are incorporated in certain chambers of the fluidic module. 2) An electronics subsystem comprised of an In-circuit microcontroller, light emitting diodes (LEDs), photosensor, heating element, temperature sensor, four indicator LEDs, battery voltage measurement circuitry, and serial interface. 3) A spike insert for the chip. 4) A bracket made of ABS. 5) A protective gasket made of rubber. 6) A thermal gap pad made of thermally conductive laminate. 7) Self-sealing vents consisting primarily of polyethylene. 8) Software, which runs on a microcontroller that coordinates and analyzes the results of a multiplexed molecular diagnostic assay. The embedded software is responsible for controlling temperature, measuring optical absorption of each reaction chamber over time, analyzing optical absorption signals and rendering a diagnostic result to the user via LED indicators. 9) Plastic housing.
