Overnight Diagnostics (OnD) is a Medicare approved Independent Diagnostic Testing Facility (IDTF) providing overnight pulse-oximetry testing and home sleep testing nationwide. Discover the advantages of OnD and why hundreds of physicians and suppliers have already made the switch.


Manage orders faster with your 'Control Panel'
OnD's Control Panel was designed to allow users to create, edit, and track orders faster. New orders are entered in seconds using auto-fill technology. Pending orders are sorted by "Status" with clear instructions on what to do next. "Alerts" keep you posted on possible errors. No more scrolling through pages or reading tiny text.

Data Processed Electronically Within Minutes
Why wait hours or days to get results? OnD's ordering system takes advantage of bar-coding technology to process new orders. Faxed prescriptions, patient authorization forms, and uploaded test results are processed within minutes. Data is reviewed for errors and uploaded to your Control Panel for immediate viewing.

System Compatible with most popular oximeters
We maintain an extensive list of uploadable oximeters compatible with OnD's system. We also add new models whenever possible.
