8. Expected waiver performance
At 3 sites, 66 untrained users with no laboratory experience tested randomized
samples using the Urispec
®
urine test strips and the Urispec
®
Plus Urine Ana-
lyzer. The CLIA waiver study demonstrated that the performance of the Urispec
®
Plus Urine Analyzer is acceptable in the hands of non-technical users when only
the Quick Reference Guide is used to learn and perform tests. The performance
of the Urispec
®
urine test strips with the Urispec
®
Plus, in the hands of the Lay-
users, met the primary performance criteria that 90% of the results should be
within ± one level of the expected results.
