IMMPROVE™ Subclass Quality Assurance Scheme

Quality Assurance

As a manufacturer of clinical diagnostic products, Binding Site is aware of the need for a high standard of quality in the laboratory. The IMMPROVE™ Quality Assurance Schemes allow the laboratory to monitor the standard of their own results over time, and compare them to other methods available. Participants in the scheme are located in more than 15 countries worldwide.

Laboratories may join a scheme at any time during the year. Each laboratory is allocated a reference number on registration and all reports are generated against the relevant number in order to preserve confidentiality.

Subclass QA Schemes

More than 170 laboratories worldwide participate in the IMMPROVE Subclass Quality Assurance Scheme.

This scheme provides a single human serum sample six times a year for analysis of the following analytes:

  • IgG, IgA, IgM
  • IgG1, IgG2, IgG3 and IgG4
  • IgA1 and IgA2
  • Tetanus toxoid IgG
  • Diphtheria toxoid IgG
  • Pneumococcal capsular polysaccharide IgG
  • Haemophilus influenzae type b IgG

The participating laboratory is asked to run the sample provided using their routine assays and report the results obtained.

Following analysis of the results, a personalised report is sent to each laboratory. The report includes full statistical analysis of results and high quality graphical representation of the data for each analyte.
