Scope

YY/T 1244-2014 is the English-translated version of 体外诊断试剂用水.

YY/T 1244 specifies the purified water used in in vitro diagnostic reagents. Water is the largest single ingredient in most diagnostic reagents and the one most likely to carry what nobody intended: ions that shift a pH, organics that quench a signal, nucleases that destroy a target, or bacteria whose growth changes a reagent over its shelf life.

Grading water by conductivity, organic carbon, microbial count and the other parameters the standard sets is what makes reagent manufacture reproducible. It sits with YY/T 1239 on prepared agar plates among the Chinese standards covering the inputs to diagnostics rather than the finished tests.

For an IVD manufacturer producing in or supplying to China, this is the specification the water system is qualified against.

Purified water for in vitro diagnostic reagents

1 Scope

This Standard specifies terms and definitions, requirements, and test methods of

purified water in-vitro diagnostic reagents.

Purified water for in-vitro diagnostic reagents can be used for in-vitro diagnostic

reagents' production, general reagent preparation in medical laboratory, instrument

and equipment cleaning etc.

If there are special requirements for reagents production, REFER to the relevant

standards or FORMULATE a special requirement (such as the special requirements

for particle by blood cell counting reagents; the special requirements for DNA

enzymes, RNA enzymes, and protease by molecular biology reagents).

2 Normative references
