Treatment of samples

No special treatment should be given to the PT samples. They [samples] should be handled in the same manner as all the other samples routinely tested in the laboratory.

 

Handling and safety requirements

Contact surfaces must be decontaminated with 70% alcohol or other suitable disinfectants. Used laboratory utensils must be cleaned and sterilized as per laboratory standard operating procedure. Unused materials and waste must be removed as per laboratory waste management protocol. This involves autoclaving and/or removal by an approved waste removal company.

 

Specific environmental conditions required for the participant to conduct tests

All cultures must be handled in a biological safety cabinet.  Minimum requirement for JGKPT06 (Brucella Culture): class 2+

 

Results recording

Only the supplied excel “Result entry forms” [R.E.F] should be used to capture the PT results. The Participants must fill in the cover page and answer all questions before capturing the results on R.E.F.

 

Submission of PT results to JGK

All results must be submitted on or before the 27th of August 2018. Any results received after this date will not be included in the analysis.
