Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory.

Quality control is a measure of precision, or how well the measurement system reproduces the same result over time and under varying operating conditions.

Laboratory quality control material is usually run at the beginning of each shift, after an instrument is serviced, when reagent lots are changed, after calibration, and whenever patient results seem inappropriate.

Quality control material should approximate the same matrix as patient specimens, taking into account properties such as viscosity, turbidity, composition, and color.

It should be simple to use, with minimal vial to vial variability, because variability could be misinterpreted as systematic error in the method or instrument.

It should be stable for long periods of time, and available in large enough quantities for a single batch to last at least one year.

Liquid controls are more convenient than lyophilized controls because they do not have to be reconstituted minimizing pipetting error.

Bio-Rad Laboratories, Inc. was founded in 1952 in Berkeley, California.

The company was initially engaged in the development and production of specialty chemicals used in biochemical, pharmaceutical, and other life science research applications.

Today, Bio-Rad manufactures and supplies life science research, healthcare, analytical chemistry, and other markets with products and systems used to separate complex chemical and biological materials and to identify, analyze, and purify their components.

A Web portal is most often a specially designed web site that brings information together from diverse sources in a uniform way.

Usually, each information source gets its dedicated area on the page for displaying information (a portlet); often, the user can configure which ones to display.

Variants of portals include mashups and intranet "dashboards" for executives and managers.

The extent to which content is displayed in a "uniform way" may depend on the intended user and the intended purpose, as well as the diversity of the content.

Very often design emphasis is on a certain "metaphor" for configuring and customizing the presentation of the content and the chosen implementation framework and/or code libraries.

In addition, the role of the user in an organization may determine which content can be added to the portal or deleted from the portal configuration.
