常见错误

❌ 错误:We need to do an immunoassay to the patient.
✓ 正确:We need to perform an immunoassay on the patient's sample.

错误在于介词使用不当。'immunoassay'是对样本进行的检测,不是直接对病人,应使用'on'表示检测对象是样本,或直接说明'sample'。

❌ 错误:The immunoassay result is positive, means he has the disease.
✓ 正确:The immunoassay result is positive, which suggests he may have the disease.

错误在于将检测结果直接等同于诊断。免疫测定结果是辅助诊断工具,需结合其他临床信息,应使用'suggests'或'indicates'等更准确的表达。

近义词辨析

bioassay

bioassay(生物测定)范围更广,指利用活体生物或生物系统进行的检测,可能包括免疫测定,但也可涉及毒性、药效等其他测试;immunoassay特指基于免疫反应的检测。

While immunoassay detects specific proteins, bioassay might measure overall biological activity in cell cultures.

serological test

serological test(血清学检测)侧重于检测血清中的抗体或抗原,是免疫测定的一种常见应用,但immunoassay还包括其他样本类型(如尿液、组织)和更广泛的分析方法。

A serological test for antibodies often uses immunoassay techniques like ELISA.
