Evaluate the performance of nucleic acid tests for determination of the presence of viral, bacterial, and fungal nucleic acids Formulated with purified, intact organisms Organisms are chemically modified to render them noninfectious Refrigerator stable—store between 2 and 8°C Purified protein matrix treated with 0.09% sodium azide 6 x 0.2 mL vials of ME Control 1 and 6 x 0.2 mL vials of ME Control 2 NATtrol products are ready-to-use, inactivated full process controls designed to evaluate performance of molecular tests. They can be used for verification of assays, training of laboratory personnel and to monitor assay-kit lot performance. NATtrol products contain intact organisms and should be run in a manner similar to clinical specimens.
