LabNow came to Wi with a robust technology for quantifying CD4 content in whole blood, however they needed assistance executing RBC (red blood cell) removal from a whole blood sample on a consumable device without centrifugation. Wi was able to demonstrate a novel method of supporting a track-etched membrane of 3 microns and designed the entire consumable cartridge. Wi designed and manufactured the consumable using the latest laser welding techniques to mitigate particulate noise in the detection process.
