Yeah I got this name especially for procuring swabs for such tests as well as other tests not related to the coronavirus. Even better, sending in test reports online, picking up swab samples from home, etc. could be some of the services offered.
Tbh, I was iffy about the name too, but with the frequent lockdowns and wave after wave of the present virus jeopardising status quo, it seems like a decent name. At least to me.
It's just the hype around these words nowadays due to covid. But exactly as @jhm said, a swab test is one of many that any lab would provide. So to call your website with this name would only be worth it if the swab test is the one and only way to detect covid. Then it would mean ''covid test'' pretty much. But it's not the case.
On top, once covid behind us one way or another, no one will pay any importance to this kind of test any longer... Better get rid of this name. Sorry to disappoint you.
