We communicate the interference of a compound of the blood collection tube with the accuracy of a validated high-pressure liquid chromatography method with ultraviolet detection for quantifying voriconazole levels, which led to false positive results. This could have serious consequences for patient management. Our advice is to implement external assessment programs.
我们报道了一种血液采集管化合物对经过验证的高压液相色谱法-紫外检测定量伏立康唑浓度的准确性的干扰，导致假阳性结果。这可能对患者管理产生严重后果。我们建议实施外部评估计划。
