One Ecosystem
Start with Lite, and move to Lab when a case needs it.
Both tests share one platform, one patient record and one interpretation pipeline, so a patient's care can change without their data starting over.
Escalate without re-onboarding
A Lite study can move to Wesper Lab on the same record when a case needs direct respiratory data.
Route from intake
An intake flag such as AFib or a complex history can route a patient to Wesper Lab from day one.
Follow up for years
Re-test over time on the same record to see whether treatment is working.
