A standard solution created from a secondary standard cannot have its concentration accurately known without stoichiometric analysis against a primary standard. An example of a secondary standard is sodium hydroxide, a hydroscopic compound that is highly reactive with its surroundings. The concentration of a standard solution made with sodium ...
A primary standard in metrology is a standard that is sufficiently accurate such that it is not calibrated by or subordinate to other standards. Primary standards are defined via other quantities like length, mass and time. Primary standards are used to calibrate other standards referred to as working standards. [1] [2] See Hierarchy of Standards.
Peer-reviewed medical journals are a natural choice as a source for up-to-date medical information in Wikipedia articles. Journal articles come in many different types, and are a mixture of primary and secondary sources. Primary publications describe new research, while review articles summarize and integrate a topic of research into an overall ...

The standard treatment, also known as the standard of care, is the medical treatment that is normally provided to people with a given condition. In many scientific studies, the control group receives the standard treatment rather than a placebo while a treatment group receives the experimental treatment. [ 1 ]
The triiodide ion solution is then titrated against standard thiosulfate solution to give iodide again using starch indicator: I − 3 + 2 e − ⇌ 3 I − (E 0 = +0.54 V) Together with reduction potential of thiosulfate: [1] S 4 O 2− 6 + 2 e − ⇌ 2 S 2 O 2− 3 (E 0 = +0.08 V) The overall reaction is thus: I − 3 + 2 S 2 O 2− 3 → S ...
The Clinical and Laboratory Standards Institute (CLSI) is a volunteer-driven, membership-supported, not-for-profit, standards development organization. CLSI promotes the development and use of voluntary laboratory consensus standards and guidelines within the health care community.
Interoperability between disparate clinical information systems requires common data standards or mapping of every transaction. However common data standards alone will not provide interoperability, and the other requirements are identified in "How Standards will Support Interoperability" from the Faculty of Clinical Informatics [2] and "Interoperability is more than technology: The role of ...
