5.0 RATING
“With regard to "someone" contacting me about lab results, those are available on the portal. We did discuss them during the visit, so that question seems ill-constructed. In the more distant past, I did receive calls from someone about my test results. I also ordered copies mailed to me. We always discuss my bloodwork during a routine appointment.”
