Major errors arise if E test strips are placed upside down. Asymmetric zones, or no zone at all, may result. MICs indicated by upside-down tests were almost always considerably higher than true values. This situation differs markedly from that for conventional testing, where orientation of disks is not important.
如果E试验条倒置放置,会出现重大误差。可能会出现不对称区域,甚至根本没有区域。倒置试验显示的最低抑菌浓度几乎总是远高于真实值。这种情况与传统试验明显不同,传统试验中纸片的方向并不重要。
