Useful Information


Our office telephones always switch over at 4:00 PM or 5:00 PM daily when our offices close.

We try to make sure that all of our patients are provided with their results by 6:30 PM daily. If you do not hear back by 6:30 PM, please call the office number to be put in contact with the nurse coordinator who is on-call. 

If you require assistance after hours for urgent matters, please call our main number at 312-288-6420 to reach the answering service to be put in contact with the coordinator who is on-call.

We utilize a Private Result Network for accessing your daily monitoring information; however, we also communicate with our patients regularly by phone and email. It is important for our active patients to be checking all three frequently.

You will not find any new information by checking the Private Result Network any earlier than 2:30 PM.
