Welcome to MMQCI’s Resource Page!

Do you need help implementing a new test? Are you struggling with determining best quality control practice? Do you want to know what professional organizations are recommending? Where to find a lab performing your new test? Looking for colleagues struggling with similar issues? We hope the information and links below are helpful to your work in the field of molecular diagnostics.

1. Clinical and Laboratory Standards Institute (CLSI), previously NCCLS, publishes guidelines which describe best laboratory practices. These guidelines are used by laboratories to implement all aspects of a quality assurance program, by laboratory inspectors, manufacturers and FDA. Click here to see a listing of CLSI guidelines that could be of particular assistance to molecular laboratories.

2. Dr. James Westgard has been the international QC guru of clinical laboratory medicine since the ‘70s. His approach to use QC routinely and apply statistical analysis with Westgard Rules to identify shifts and trends in test systems has become traditional throughout established laboratory disciplines. The Westgard website is an excellent source of information regarding traditional QC practice which can be applied to molecular testing.

3. A paper by S. Liang of John Hopkins illustrates the traditional use of quality controls and Westgard Rules for a complex molecular test. Application of Traditional Clinical Pathology Quality Control Techniques to Molecular Pathology

4. Accurate pipetting is key to accurate results in molecular diagnostics. Click here for 10 Tips on accurate pipetting.

5. Professional organizations are excellent sources of information, policies and latest news in the molecular testing community:
