Quality Assurance and Control
Consistent, accurate results have always been our first priority. Highly trained personnel, the latest instrumentation and methodologies, continuing client education, powerful data management and extensive quality assurance all contribute to the exceptional quality we demand.
An extensive quality program allows the monitoring of precision, accuracy and detection limits of our analytical measurements. For example, data review is performed on every QC sample and every patient result, to assure that all quality criteria are met and that critical values are checked. Samples are also sent to other laboratories to compare results.
The program also covers other aspects of our service, such as the time required to provide results, the cost of analysis, results interpretation, customer service and more. As a result, you can enjoy more timely, reliable, clinically relevant results that represent great value to your patients.
Ongoing analysis of quality control samples and participation in proficiency testing programs, including the College of American Pathology, assure that the precision and accuracy of DDI results meet your clinical needs. What's more, our involvement in scientific research ensures that we fully understand the nuances of our clinical data, and we can share that learning with you.
DDI supports cutting-edge research in participation with prominent global institutions.
One of our driving research goals has been to bring greater awareness of the function of elements in clinical biochemistry and medicine. We have been actively involved in studies dealing with important subjects such as:
- Intellectual and neurological development and behavior in children
- The adverse effects of toxic waste and heavy industrialization on hypertension, cardiovascular disease and other conditions
- The biochemical connection between aberrant behavior and violence in juveniles and adults
- Zinc deficiency and suppression of growth in humans
We have partnered with Argonne National Laboratory, Brookhaven National Laboratory, Johns Hopkins Hospital, the European Commission Joint Research Centre, the United States Navy, the California Criminal Justice System, the Oklahoma Department of Health and Human Services, the Universities of California, Florida, Illinois and Texas, and many others.
As part of our commitment to helping answer important biomedical questions, we welcome research proposals and seek collaboration with strong clinical practitioners who are equally committed to improving health and advancing basic knowledge of element function and metabolism.
Clinical Laboratory and Technologies
Doctor's Data has spared no effort in creating a modern physical plant equipped with the most advanced instrumentation available to support our scientific team. The laboratory is a model of innovation, featuring state-of-the-art design, systems and materials which support our exacting work through optimal cleanliness, contamination control and streamlined specimen flow.
Our expertly trained team is supported by advanced instruments such as dynamic reaction cell inductively coupled plasma mass spectrometry (DRC-ICP/MS) for elemental analysis, DNA amplification assays, and automated identification and antimicrobial sensitivity instruments for recognition of bacterial resistance mechanisms and phenotypes in our clinical microbiology department.
In the interest of accurate, sensitive and cost effective analysis, we have always employed the best-available techniques. In fact, DDI was one of the first clinical reference laboratories to employ ICP-MS and high-resolution ICP-MS. We are also leaders in GC/MS, UHPLC, LC/MS QQQ and the latest in automated microbiology systems.
