Interference
The interference study was conducted using medically relevant concentrations of the potentially
interfering substances listed below with two strains each of influenza type A and type B to assess the
potential interference of the substances on the performance of the OSOM Ultra Flu A & B Test.
The test was conducted by spiking each substance into samples containing the lowest detectable virus
level of influenza Type A or Type B for the positive interference testing and into samples without influenza
virus for the negative interference testing. Each substance had no inhibitory effect on the OSOM Ultra
Flu A & B Test at the concentration listed in the table below.
