Flowflex™ is authorized by FDA under an EUA and has the CE Mark for self-testing, is available in more than 100 countries around the world and is used by the National Health Service (NHS) in the United Kingdom as well as by governments and medical associations in the United States, Singapore, Australia, and many more. FlowFlex™ is suitable for use in individuals with and without COVID-19 symptoms, and for children as young as two years old.
FlowFlex™, which received its FDA EUA authorization* on Oct 4th, 2021, was instrumental to doubling the supply of rapid antigen test kits in the United States, having ramped up production to more than 200m test kits on a monthly basis.
"We are grateful to partner with ACON Bio, given the urgent need for rapid testing in Hong Kong. With our partnership, we aim to supply millions of testing kits and make it the most affordable FDA EUA authorized rapid test in Hong Kong," said Danny Yeung, CEO and Co-Founder, Prenetics. "By providing near instant results without the need for specialist equipment or to visit testing facilities, Flowflex™ can provide reassurance before visiting family and friends, particularly those who are more vulnerable."
To make it much more accessible to the general public, Flowflex™ will be priced significantly below the market average of HKD120 for other FDA EUA approved rapid testing solutions in Hong Kong.
The Flowflex™ Antigen Rapid Test Kit will be made available in the following packs:
1 Pack – HKD 75
5 Pack – HKD 350 (70 / test)
25 Pack – HKD 1500 (60 / test)
