●问题3

货号：abx055867

品名：Human BK Virus IgG (BKV-IgG) ELISA Kit

品牌：ABBEXA

原文：

Q:Cut-off Value Calculation: Is the cut-off value calculated as the mean OD of negative controls (NC) + 0.15?

Low NC OD Values: If the OD value of the negative control is very low (e.g., below 0.05), should the cut-off still be calculated using the actual NC OD value + 0.15, or is there a minimum threshold that should be applied?

Limit of Detection (LOD): What is the limit of detection for this kit?

A:Thank you for your mail. The cut-off value is calculated as the mean OD of the NC + 0.15. There is no minimum threshold for the NC value.

I am requesting the limit of detection from my colleagues in the lab and will get back to you as soon as possible.

译文：

问：临界值计算：临界值是否按照阴性对照的吸光度均值加0.15计算？

阴性对照吸光度低值问题：若阴性对照的吸光度值极低（如低于0.05），临界值是否仍按实际阴性对照吸光度值加0.15计算，还是有相应的低阈值标准？

检测限：该试剂盒的检测限是多少？

答：感谢你的来信。临界值的计算方式为阴性对照（NC）的吸光度均值加0.15，阴性对照的吸光度数值无低阈值要求。

我正在向实验室同事咨询该产品的检测限相关数据，会尽快回复你。
