The science behind HALO

Our state-of-the-art automated labs extract RNA from your saliva sample and test for a gene that is only present in SARS-CoV-2 using RT-qPCR, enabling us to detect the virus even before symptoms start to show. This delivers almost 100% accuracy and reduces inconclusive testing to less than 2%.
