LabNow

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.

LabNow Features:

• Capillary channel design
• On card RBC/WBC blood separation
• Dried-down antibodies with fluorophore tags on-device
• On card waste containment with biologic isolation
• Small volume segmentation <3uL +/-  ½ %
• Air Bubble removal and management
