Criteria For Acceptable Performance

ProcedureAcceptable
Performance
Virus isolation and Identification 80%
Direct Antigen Testing Influenza 80%
Direct Antigen Testing RSV 80%
Direct Antigen Testing ROTA 80%

 

Grading

Grades are determined as follows:

Isolation/Identification

Sample Score = (Number of acceptable responses / Number of viruses present + Number of Incorrect Responses) X 100
Event Score = Sum of sample scores / Total number of sample scores

Qualitative Antigen Tests

Note: For laboratories performing influenza rapid testing with kits that only detect influenza virus type A, their results will be scored solely on the basis of their detection of influenza A.

Presence or Absence of the viral antigen

Event Score = (Number of acceptable responses / Total number of samples tested) X 100

Failure to attain an overall testing score of at least 80% is unsatisfactory performance.
