What our physician partners have to say

Ziad F. Gellad, MD, MPH

The transition from in-office to at-home breath testing was relatively seamless with CDI. It was very easy to order the testing online, and the results were reliably returned to me electronically. Many of my patients appreciated the ability to complete this testing at home, especially when the pandemic was at its worst.

Arnab Ray, MD

The implementation of breath testing has been a major improvement in patient care for our practice. Bloating is an extremely common and frustrating complaint from patients that we can now provide an answer for in many cases.

Aliza Cicerone, ND, FABNO

Breath testing has been hugely beneficial for my practice for many years. It allows me to help patients who have seen multiple doctors without finding the cause of their problems, and who continue to struggle with digestive dysfunction.

Shashi Kumar, MD

It can be challenging to diagnose IBS-D and malabsorption in a busy clinical practice. Having an objective marker to diagnose and reassure the patient and provider is a great asset in my practice. It also helps me to manage the condition by using appropriate treatment.
