Maintaining Quality Control Types

Overview

Quality control types are the blank, QC standard, QC spike, replicate, reread and duplicate samples added to an analytical run to measure analytical accuracy, and to warn analysts that analysis is outside accepted tolerances.

This process is pertinent to laboratory and QC managers who configure the analytical environment for the laboratory, especially with regard to quality control requirements.

Types of Quality Control Materials

Quality control types are grouped by the base quality control type of BLK (Blank) and STD (Standard). For each quality control type under the base type, quality control type schemes are created to hold the analytical limits for each associated scheme. So, essentially, quality control type schemes are maintained. Therefore, quality control types are defined after schemes and analytes are created.

Use of Quality Control Samples

When a blank or quality control standard or spike sample created, it is linked to a scheme in the job. When a result is entered for a CUID scheme analyte, it is assessed the quality control type scheme analyte's limits.

Process

Quality control types are maintained using the Method application. You need specific rights to have visibility to this application.

Quality control types are maintained using simple SCRUD (search, create, review, update, delete) functionality under the Methods » QC codes node. You need specific rights to have visibility to this node.

Maintain quality control types for schemes

To pass quality control testing, a quality control CUID scheme analyte's result must try to achieve the quality control type scheme analyte's Expected value, within a specified relative or absolute tolerance. The tolerance determines the lower action limit, lower warning limit, upper warning limit and upper action limit. These limits are set up in the quality control type scheme analyte.
