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

JGKPT06 (Brucella Culture) must be handled in a biological safety cabinet 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.
