NATtrol EV Positive & Negative Control



NATtrol™ EV External Run Controls

Catalog Number: NATEVPOS-6MC

Catalog Number: NATEVPOS-6MC



NATtrol™ Enterovirus (EV) External Run Controls (NATEVPOS-6MC, NATEVNEG-6MC)* are formulated with purified, intact virus particles that have been chemically modified to render them non-infectious and refrigerator stable. Each control contains 6 x 0.2 mL vials of NATtrol™ Coxsackievirus or NATtrol™ Parechovirus. These controls are supplied in a purified protein matrix that mimics the composition of a true clinical specimen.


  • NATtrol™ EV External Run Controls are full process controls designed to evaluate the performance of nucleic acid tests for determination of the presence of EV nucleic acids. NATEVPOS-6MC and NATEVNEG-6MC can also be used for quality control of clinical assays and training of laboratory personnel.
  • NATEVPOS-6MC and NATEVNEG-6MC contain intact virus particles and should be run in a manner similar to that used for clinical specimens.


  • NATtrol™ inactivation was carried out on the virus stocks used to formulate each control pack. The inactivation was verified by the absence of viral growth in validated tissue culture based infectivity assays.
  • Purified protein matrix used in the manufacture of this product is treated with 0.09% sodium azide. It was manufactured from materials that have been tested and found non-reactive at the donor level for HIV-1/HIV-2 Antibody, HBsAg and HCV Antibody by FDA licensed donor screening test methods. All materials are also tested for HIV-1 and HCV by FDA approved Nucleic Acid Test (NAT) methods. Heat inactivated bovine based source materials used in the manufacture of this product meet applicable USDA requirements for abattoir sourced animals, traceability and country of origin. The materials were collected at USDA licensed establishments or legally imported from countries recognized by the USDA as negligible or controlled for risk for Bovine Spongiform Encephalopathy (BSE) and other exotic disease agents. Donor animals were inspected ante and post mortem at the abattoir as required by the USDA.


  • Although NATtrol Influenza/RSV External Run Controls contain inactivated organisms, they should be handled as if potentially infectious.
  • Use Universal Precautions when handling these products.
  • To avoid cross-contamination, use separate pipette tips for all reagents.


  • NATtrol™ EV External Run Controls should be stored at 2-8°C.


  • Shake NATtrol™ sample vigorously for 5 seconds.
  • Follow the assay manufacturer’s instructions for use to process the sample as a clinical sample.


  • Qualitative results are shown in Table 1 below.
  • Each laboratory must evaluate the controls and establish their own acceptance criteria.
