Chat about Novel Coronavirus - 2019-nCoV - COVID-19

Hmm, thanks all. Sounds like it will work but the Gov. guidelines are clear so I have emailed them pointing this out and asked them for a second reference no.

Said Government guidelines FWIW:

At the time the test package is booked, the test provider must provide a single test reference number to the person booking the test. If the provider sells multiple test packages to one person, each test package will require its own booking reference.
