The StatLIA Immunoassay Troubleshooting Chart was designed to assist the laboratory in troubleshooting assays that StatLIA has flagged. Two examples showing the troubleshooting process can be viewed by clicking on the links below.
In Example 1, a control specimen concentration was flagged, yet there was nothing wrong with the assay. This information helped the laboratory diagnose the problem immediately and avoid the time and expense of repeating the assay. As you will see in the example, StatLIA makes it easy to distinguish between a bad assay and a good assay with a bad control specimen.
In Example 2, the assay was flagged by StatLIA, yet the control specimen concentrations were within range. StatLIA flagged the assay and alerted the laboratory to the fact that the assay was bad and the results unreliable. By monitoring standard curve parameters as well as control specimen concentrations, StatLIA is able to easily flag the assay and pinpoint the problem before the assay is accepted.
