Why Settle For Less? DDI Brings You Truly
Comprehensive Stool Analysis

It has been 3 years since Doctor's Data introduced the revolutionary proteomic technology known as MALDI-TOF Mass Spectrometry to the functional medicine industry. In this short period of time, our team has made groundbreaking discoveries, technological advances and developed an unrivaled expertise for clinically relevant assessment of the gastrointestinal (GI) microbiome. We'd like to share some highlights about our experience and how we have raised the bar.

The Doctor's Data Advantage

Doctor's Data uses the most expansive open reference database available for identification for GI bacteria and yeast. Our high-complexity microbiology combined with MALDI-TOF proteomic methodology affords the opportunity to identify over 1,400 bacteria and yeast, including 84 Clostridium spp. and 170 species of yeast (80 Candida spp.).

Enhanced Inflammation Detection
Earlier this year Doctor's Data added a newly available monoclonal Calprotectin assay as an inflammatory marker to our Comprehensive GI profiles. The new Calprotectin assay is more sensitive than both our quantitative Lactoferrin and the older polyclonal Calprotectin immunoassays. Combining new Calprotectin and quantitative Lactoferrin assays as standard inflammatory markers in our stool analysis provides clinicians with the most comprehensive approach for evaluation of very serious IBD verses inflammation that may be associated with enteropathogens or IBS.

Unparalleled Parasite Detection

Employing gold standard O&P Microscopy along with Enzyme Immunoassays (EIA), parasite identification is done differently at Doctor's Data. When multiple specimens are provided for parasitology, each specimen is concentrated and analyzed independently rather than being combined - a total of six slides for a Parasitology x 3. Research has clearly demonstrated that combining all three specimens does not improve detection of parasites, including protozoa, despite unfounded claims to the contrary.
Research and Support
Staying in touch with the latest scientific research, Doctor's Data continues to lead the pack in disseminating important, clinically relevant information regarding the GI microbiome, health and systemic diseases. Our scientific team is well equipped to support practitioners to aid in interpretation of test results and better patient outcomes.

What The Future Holds
An advantage of using the expansive open reference library is that the database remains in a continual state of growth as we are able to uncover new findings. Recently, the Department Manager of Microbiology at Doctor's Data, Hope Beilfuss, published a peer-reviewed paper on the first definitive identification of the Laribacter hongkongensis species in the United States (see abstract below). This particular organism is misidentified by other phenotypic methods and undetectable by more limited MALDI-TOF databases, further demonstrating the advanced capabilities and use of an open library. As we continue to make advances in the lab, it is our mission to provide the most comprehensive and clinically relevant evaluation into the realm we know as the GI microbiome.
