As per an external fact check, the brand PRIMACOVID belongs to a company in Switzerland. The mobile number advertised with the post, as the person to contact if one needs to get these test kits delivered, belongs to Wasantha Samarasinghe, member of JVP.

The number advertised there belongs to Dr. Nalinda Jayatissa, member of JVP.
