A

accuracy

The closeness of agreement between a result and the accepted reference value. Accuracy, when applied to a set of test results, involves a combination of random components and a common systematic error or bias component.

active rule

A SPC rule with a status of warn or reject.

Affiliated Data Exception Report

Note: Affiliated Reports are optional. Contact your Bio-Rad QC Program Representative to request Affiliated Reports.

For all laboratories within the affiliated laboratory consensus group, this report shows any analyte:

• Exceeding a specified SDI or CVR warning limit compared to the consensus group.
• Rejected by the Unity™ Interlaboratory Program.
• Containing a suspected coding error such as invalid unit, invalid method, and so on.

affiliated group

A group of laboratories in the Unity™ Interlaboratory Program comparing their results and essentially become their own consensus group. Contact your Bio-Rad QC Program Representative to request any of the available Affiliated Reports.

Affiliated Laboratory Comparison Report

Note: Affiliated Reports are optional. Contact your Bio-Rad QC Program Representative to request Affiliated Reports.

The Affiliated Laboratory Comparison Report summarizes the performance of each participating affiliated laboratory in a single report. Statistics are provided for your laboratory and all affiliated laboratories and include:

• Mean
• Standard deviation (SD)
• Coefficient of variation (CV)
• Coefficient of variation ratio (CVR) and Standard deviation index (SDI)
  • Lab to Peer Group
  • Lab to Lab Group (affiliated group)
• Number of points

Affiliated Laboratory Comparison Report: Abbreviated Summary

Note: Affiliated Reports are optional. Contact your Bio-Rad QC Program Representative to request Affiliated Reports.

This report is designed for a quick review and focuses on key statistics to provide a performance summary for multiple laboratories. This report summarizes the performance of each participating affiliated laboratory in a single report. For each test, this report shows:

• Mean
• Standard deviation (SD)
• Coefficient of variation (CV)
• Number of points
• Coefficient of variation ratio (CVR) compared to the Peer, Method, and Affiliated consensus groups
• Standard deviation index (SDI) compared to the Peer, Method, and Affiliated consensus groups

Affiliated Reports

Note: Affiliated Reports are optional. Contact your Bio‑Rad QC Program Representative to request Affiliated Reports.

Affiliated Reports allow a group of laboratories to compare results, essentially creating their own consensus group. The Unity™ Interlaboratory Program provides the following Affiliated Reports:

• Affiliated Laboratory Comparison Report
• Affiliated Laboratory Comparison Report: Abbreviated Summary
• Affiliated Data Exception Report

all labs group

One of the available Unity™ Interlaboratory Program consensus groups. The All Labs consensus group is composed of data from all laboratories reporting for the same lot number, level, units, and temperature of a test.

analyte

A substance or chemical constituent being analyzed such as glucose, TSH, and so on.

analytical process

A series of steps taken in the analysis or testing of patient specimens or samples.

audit trail

A secure, computer generated electronic record allowing reconstruction of the course of events relating to the creation, modification, and deletion of an electronic record.
