It is important that laboratories use control strains from recognised sources to ensure that the strains are fully characterised and authentic this also helps standardise the quality of testing across the country.
Laboratories frequently prepare in house reference stocks of the control strains for daily use. Those reference stocks must be managed carefully to ensure the strains are not sub-cultured (passaged) too frequently because this may lead to genetic variation and/or contamination.
