Yes, quantification ranges, called lower and upper limit of detection (LLOQ, ULOQ) can be included in WebIDQ results exports. The option “Show analytical details” needs to be activated. See WebIDQ user manual, section “Display options”, https://webidq.biocrates.com/manual/Results/123872#185004.

Can they be included in WebIDQ results exports?

Analyzing the same sample with different kit runs may lead to slightly different results. This applies especially for metabolites of the analyte classification T2, see WebIDQ user manual, section “Analyte classification”, https://webidq.biocrates.com/manual/quantification/264082#282596. To receive reproducible results, applying target value normalization is recommended, see WebIDQ user manual, section “Data normalization”, https://webidq.biocrates.com/manual/Results/123872#172910.

What is the reason for this?

MS sensitivity loss is commonly seen first in negative ion mode. The MS mass accuracy may be a bit off. Tuning and calibrating of the MS in positive and negative ion mode may solve the issue.

How can this issue be solved?
