Is Quest Quanum® Utilities safe?
Quest Quanum® Utilities bridges page requests to a local native messaging host for label printing.
The extension relays messages from the web page to a locally installed native application (com.questdiagnostics.chromenative.labelprinting) via Chrome's native messaging API. Any data the page sends in a QUEST_UTILITIES_REQUEST postMessage — including base64-encoded payloads — is forwarded to the local host and responses are returned to the page. No data is transmitted to external servers.

Where it sends data
Destinations our analysis observed Quest Quanum Utilities contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
