CEQAL collaborates directly with POCT device manufacturers to design and implement customized EQA programs. These programs help ensure that test results generated in the field are consistent and traceable to a central lab. They are tailor-made to the requirements of a given test and use the same high quality samples found in our accuracy programs. Target values are set to challenge operators at the most clinically significant levels and performance is evaluated within the peer group at the end of each event, using customized online reporting tools. Contact us for more information on these exclusive programs or if you wish to create your own.

This program was developed in collaboration with bioLytical Laboratories to specifically monitor the accuracy of interpretation of their rapid INSTI HIV-1 / HIV-2 point-of-care test. Samples have been customized with known amounts of the IgG antibody with particular emphasis at the ‘weak-positive’ level where false negatives are most likely to occur.
Participants are assessed based on the accuracy of reported results (i.e. non-reactive, reactive) relative to the presence of HIV-1 / HIV-2 antibody in each sample. Correct interpretations are revealed automatically at the time of submission.
Results are submitted online through CEQAL’s secure web platform and tallied in real time. Participants can compare their answers to the correct interpretations and see the performance of other labs within their network.
