Diagnostic Immunology/HIV Proficiency Testing Program

Grading Policy

Laboratories are evaluated on the basis of their responses for each analyte and on overall performance for all the analytes tested in the permit category. Appropriate responses are determined by participant consensus requiring 80% agreement in each test.

Grading Criteria:

• Results for analytes your laboratory tests which are left blank will be considered incorrect and be given a score of 0%. If, for some reason, your laboratory is unable to process the samples for an analyte please notify us prior to submission of test results.
• When both qualitative and quantitative results are reported ten points are deducted for each incorrect result. When only qualitative OR quantitative results are reported twenty points are deducted for each incorrect result.
• For Diagnostic Services, failure to attain an overall testing score of at least 80% is unsatisfactory performance.
• For Donor Services, failure to attain an overall testing score of 100% is unsatisfactory performance.
• For HIV, failure to attain an overall testing score of 100% is unsatisfactory performance.
• Laboratories failing two out of three consecutive proficiency test events for an analyte or for the permit category will fail the proficiency testing program for the analyte or for the permit category and may be required to cease patient testing for that analyte/category.
