NATtrol™ Influenza/RSV Negative Control (MDZ045) is an in vitro diagnostic external run control intended for use in evaluating and monitoring of qualitative molecular diagnostic assays for the detection of the absence of Influenza/RSV nucleic acid. The routine and repetitive use of external run controls enables laboratories to monitor daily test variation, lot-to-lot test kit performance, individual operator variation, and can provide assistance in identifying increases in random or systemic error.
The NATtrol™ Influenza/RSV Negative Control contains intact organisms and should be run in a manner identical to that used for clinical specimens.

NATtrol™ Influenza External Run Controls (NATFLUAB-6C and NATCXVA9-6C)* are formulated with purified, intact virus particles that have been chemically modified to render them non[1]infectious and refrigerator stable. Each control pack contains 6 x 0.5 mL vials of NATtrol™ Influenza A/B or NATtrolTM Coxsackievirus A9 (Negative Control). These controls are provided in a proprietary matrix. *Pat.:


  • NATtrol™ Influenza External Run Controls are full process controls designed to evaluate the performance of nucleic acid tests for determination of the presence of respiratory virus nucleic acids. NATFLUAB-6C and NATCXVA9-6C enables laboratories to monitor test variation, lot-to-lot test kit performance, operator variation, and can provide assistance in identifying random or systemic error.


  • NATtrol™ inactivation was carried out on virus stocks used to formulate the controls. The inactivation was verified in a standard microbiological growth protocol.
  • This product contains inactivated microorganisms and materials of human and animal origin. Safe practices suggest that the controls be considered potentially infectious and to use Universal Precautions when handling.
  • Refer to CDC guidelines and local regulations for handling and disposal.
  • The matrix used in the manufacture of this product is treated with 0.09% sodium azide. It was manufactured from Human Serum Albumin that has been tested and found to be non-reactive at the donor level for HIV-1/HIV[1]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 Fetal Bovine Serum used in the manufacture of this product meets 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.
  • Do not use past the expiration date on the label.
  • To avoid cross-contamination, use separate pipette tips for all materials.


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


  • Mix tube vigorously for at least 5 secs.
  • Process according to manufacturer’s instructions for sample to result assays.
  • Extract nucleic acid prior to use in downstream assays that are not sample to result.


  • Quality control materials should be used in accordance with local, state, federal, and accreditation requirements.
  • This product is not intended to replace the manufacturer’s controls provided with the assay.


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

    INFLUENZA/RSV NEGATIVE My search on the internet turned up nothing else but this site, so once I received it, the shipping was quick via courier and it was incredibly low priced. So I gave this product five stars.
