摘要:

免疫透射比浊法检测结果的准确性常受到一些干扰因素的影响,如样本性状、内源性干扰、钩状效应和携带污染等,这些干扰因素可使检测结果假性升高或降低,影响临床诊断和治疗监测等。文章对免疫透射比浊法常见的干扰因素及机制进行综述,以帮助检验人员识别和确认可能存在的干扰,及时纠正检测结果,尽可能减少不良后果的发生。

Abstract:

The accuracy of turbidimetric immunoassay is affected by a few interference factors,such as sample appearance,endogenous interference,hook effect and carry-over contamination. These interference factors may cause the results increasing or decreasing falsely and further affect clinical diagnosis and treatment monitoring. The laboratory staff should be familiar with common interference factors and mechanisms,communicate with doctors in time and identify,confirm and prevent possible interference,in order to reduce the occurrence of adverse events.

Key words: Turbidimetric immunoassay, Sample appearance, Endogenous interference, Hook effect, Carry-over contamination, Interference
