Not to be grim about it but everyone may want to consider doing your paperwork for medical power of attorney and/or a health directive. At the very least partners should consider adding each other as trusted "https://healthy.kaiserpermanente.org/health-wellness/life-care-plan/choose-agent" (which is what Kaiser calls it). You'd be able to access tests and communicate with Doctors on behalf of each other.
Having gone through this I feel very fortunate that I was able to make medical decisions for another and knew what the right thing was to do.
