The Manufacturer Report is provided through the Unity™ Interlaboratory Program and is a subset of the information from the Worldwide Report separated by the instrument manufacturer. The Manufacturer Report is a good reference to use when evaluating a new instrument or kit and is updated every month.
For Bio-Rad controls, the master lot number is the 5-digit lot number, ending in zero, which includes all levels of the control product (for example, 40910). To identify the levels of a control product, the final zero is changed to the level number (for example, 40911 is level 1, 40912 is level 2, and 40913 is level 3).
The substance containing the analyte being tested (for example, serum, urine, spinal fluid, whole blood).
The condition existing when Westgard Advisor™ online is unable to suggest rules meeting your quality specification (TEa). This condition indicates the test process has such a low process capacity (high total error) it cannot be controlled to a defined level of quality. The default maximum QC procedure is a Westgard multirule applying every possible rule.
The mean for a group of data points is simply the arithmetic average. The mean provides a laboratory's best estimate of the analyte's "true" value for a specific level of control. The mean ± a predetermined number of standard deviations represents the error expected in a test when the analytical system is stable. Use the following formula to calculate the mean:
The middle value in a distribution, above and below which lie an equal number of values.
The way by which an analyte is measured (for example, hexokinase).
One of the available Unity™ Interlaboratory Program consensus groups. The Method consensus group is composed of all laboratories using the same lot number, level, analytical method, units and temperature of a test. Use the Method group when there is an insufficient number of laboratories in the Peer group.
The Monthly Evaluation Report is automatically generated each month you submit data. The Monthly Evaluation Report validates the monthly laboratory performance as compared to the Peer group. This report identifies when the monthly laboratory performance does not statistically compare with or was not accepted into the Unity™ database. Also, the Monthly Evaluation Report notifies the laboratory when its data was not received in time for the comparison.
