And you, having to comply with HIPPA, should know this more than anyone. Nothing is as restrictive as HIPPA. You can call the house of a patient, have met the husband of the patient, know it's the husband of the patient, been told by the patient that it's her husband, and told by the patient you can talk to her husband about it, but by law (and you can lose your license) you can't tell the husband the results of the test.
Even if you are both in the same PTA and you play bridge with them both on the weekends, your kids have grown up with their kids, but if you tell the husband the results of a simple test, you could lose your license.
