International reference standards for antibiotics (WHO)

The World Health Organisation (WHO) International Standards for Antibiotics (ISA) are global benchmarks intended for the establishment of secondary standards subsequently used in laboratory tests or assays. These ISA standards are essential in the standardisation and quality control of antibiotic material and pharmaceutical products, and are supplied for assays described in the specifications for quality control of antibiotic material.
The EDQM has, since 2006, been responsible for the establishment, storage and distribution of these WHO ISA materials.
