4.1.24 At the same time get ready a chamber control through the sterility consider two tubes, one is SCDM & other a person is FTM tube, unplug the cotton plug with the tube and expose in LAF all through sterility, immediately after completion of sterility re-plug the tubes then incubate the tubes to be a chamber Management.
A positive consequence means that the sample includes practical microorganisms, which necessitates further more investigation and could result in the rejection on the batch.
