... The net result of these high titer controls in the LIPS format was a much higher cut-off with an AUC value of 0.83 for test performance. The AUC value for QLIPS test was 0.85 and was slightly higher ... As an alternative, rapid tests such as lateral flow immunoassays, which can more easily be integrated in point of care settings, are used for the diagnosis of several infecti...

... that avoid the extremes of motion, since torsional forces are increased at extreme forward flexion for example. The present study used load versus displacement as measures of construct integrity. ... loads for 3000 cycles at 1 Hz starting with 180 N and increasing by 180 N with sampling at 2 Hz. Failure was defined as 10 mm of displacement or catastrophic construct failure prior...
