Our FlowFlex COVID-19 Rapid Antigen Lateral Flow Test

The UK Government Public Health England has validated our test to have exemplary accuracy at multiple viral loads, including for asymptomatic patients, and across the new different variants.

Our swab only needs to go 1-2cm into the nostril, all other nasopharyngeal tests have to be performed by a doctor and need to go 9-10 cm deep into the nasal cavity.

The FlowFlex test is a true nostril swab test and has only ever been designed as such. The easy to use format of the test makes it extremely easy to test yourself and your family from the comfort of your own home.

All of our components, including our comfortable swab, are extremely well made and are designed to be as easy as possible to use. Every aspect of the test is that of a blue-chip high-quality product. CE Mark for Home Use – Fully Approved.

* The USA removed travel restrictions on June 12, other countries still might require clinician-supervised Standard or Premium Antigen tests.

This is an FDA-approved testing method that includes observation and ID verification.
