INTENDED USE

The BIOFIRE® SHIELD™ Control Kit for the BioFire® Global Fever Panel contains Positive and Negative External Controls intended for use as assayed quality controls to monitor the performance of in vitro diagnostic laboratory nucleic acid testing procedures for the qualitative detection of chikungunya virus, dengue virus (serotypes 1, 2, 3, and 4), Leptospira spp., and Plasmodium spp. (including species differentiation of Plasmodium falciparum and Plasmodium vivax/ovale) on the BioFire® Global Fever Panel performed on BioFire® FilmArray® 2.0 and BioFire® FilmArray® Torch Systems. The BIOFIRE SHIELD Control Kit for the BioFire Global Fever Panel is designed for and intended to be used solely with the BioFire Global Fever Panel. This product does not replace manufacturer internal controls provided as part of the BioFire Global Fever Panel device. Both the Positive and Negative External Controls are provided in a FilmArray Control Injection Vial format. The Positive Control Injection Vial contains dried synthetic DNA segments in buffer and stabilizer to assess the presence of each individual assay on the BioFire Global Fever Panel. The Negative Control Injection Vial contains no DNA and is nonreactive with the BioFire Global Fever Panel assays.

PRODUCT SUMMARY AND PRINCIPLE

The BIOFIRE® SHIELD™ Control Kit for the BioFire® Global Fever (GF) Panel is a surrogate control to monitor performance of the BioFire GF Panel analytes. The BIOFIRE SHIELD Control Kit for the BioFire GF Panel is designed to mitigate the risk of control contamination or misuse when evaluating clinical specimens on the BioFire® FilmArray® systems. Good laboratory practice recommends running positive and negative external controls regularly. Evaluation of external controls is recommended prior to using a new shipment or new lot of BioFire GF Panel Kits, when there is a new operator, and following replacement/repair of a BioFire FilmArray 2.0 or Torch system. It is the responsibility of each laboratory to determine the frequency of external control testing with the BioFire GF Panel as part of the laboratory’s Quality Control program. Quality control materials should be used in accordance with local, state, federal regulations and accreditation requirements.

COMPOSITION

The BIOFIRE SHIELD Positive External Control for the BioFire GF Panel is a surrogate external assayed quality control material composed of a pool of synthetic target DNA sequences that each produce a signature melting temperature (Tm) value that is distinct from that produced by the corresponding pathogen to reduce the risk of false positive results. No synthetic target DNA sequences are present in the BIOFIRE SHIELD Negative External Control for the BioFire GF Panel. The SHIELD Control Kit for the BioFire GF Panel contains no biological hazards and is 100% non-infectious.

STORAGE AND STABILITY

Store the BIOFIRE SHIELD Control Kit for the BioFire GF Panel at room temperature (18-30°C).
Avoid storage of any materials near heating or cooling vents, or in direct sunlight.
Once the BIOFIRE SHIELD External Control packaging has been opened, the control should be loaded as soon as possible (within approximately 30 minutes). See the BioFire Global Fever Panel Instructions for Use for more information.

INTERPRETATION OF RESULTS

The External Control Report is automatically displayed upon completion of a run and can be printed or saved as a PDF file. The Run Information section of the report provides the Sample ID, time and date of the run, and the Internal Controls results. Refer to the BioFire Global Fever Panel Instructions for Use for more information about Internal Controls results. The Run information section also includes pouch information (type, lot number and serial number), run status (Completed, Aborted, Instrument Error, or Software Error), the protocol used to perform the test, the identity of the operator who performed the test, and the instrument used to perform the test. When the BioFire Global Fever Panel pouch is used with the External Controls, the results presented are for the BioFire Global Fever Panel pathogen targets only.

EXTERNAL CONTROL REPORT WHEN USING THE BIOFIRE GLOBAL FEVER PANEL
When running the BIOFIRE SHIELD Control Kit on the BioFire Global Fever Panel the results are listed in the Result Banner as either Passed (See Figures 1 and 3), Failed (See Figures 2 and 4) or Invalid (not shown).

BIOFIRE SHIELD CONTROL KIT RESULT EXPLANATION

The Positive External Controls produce a signature melting temperature (Tm) value that is distinct from that produced by the corresponding pathogen to reduce the risk of false positive results. The Positive External Control passes when the software detects amplification within the control melting temperature window for all assays. The Negative External Control passes when the software detects no amplification within both the control melting temperature window or the pathogen melting temperature window for all assays. See Table 1 for an explanation of how the Positive External Control results are analyzed, possible results, and required actions. See Table 2 for an explanation of how the Negative External Controls are analyzed, possible results, explanations, and required actions.
