Special Conditions for Use Statement: For Prescription Use Only

Special Instrument Requirements: BD MAX™ Enteric Bacterial Panel and BD MAX™ Extended Enteric Bacterial Panel are performed on the BD MAX™ System

Device Description

The BD MAX™ Enteric Bacterial Panel and BD MAX™ Extended Enteric Bacterial Panel assays along with the BD MAX System are comprised of an instrument with associated hardware and accessories, disposable microfluidic cartridges, master mixes, unitized reagent strips, and extraction reagents. The instrument automates sample preparation including target lysis. DNA extraction and concentration, reagent rehydration, target nucleic acid amplification and detection using real-time PCR. The assay includes a Sample Processing Control (SPC) that is present in the Extraction Tube. The SPC monitors DNA extraction steps, thermal cycling steps, reagent integrity and the presence of inhibitory substances. The BD MAX™ System software automatically interprets test results. For the BD MAXTM Enteric Bacterial Panel and BD MAX™ Extended Enteric Bacterial Panel, a test result may be called as POS, NEG or UNR (Unresolved) based on the amplification status of the targets and of the Sample Processing Control. IND (Indeterminate) or INC (Incomplete) results are due to BD MAX™ System failure.

Test Principle

The BD MAX™ Enteric Bacterial Panel and BD MAX™ Extended Enteric Bacterial Panel assays are designed for use with unpreserved or Cary-Blair preserved stool samples. Unpreserved samples are placed in a BD MAX sample buffer tube (SBT) with a 10 uL transfer loop for analysis on the BD Max System. The current Cary-Blair preserved specimen claim utilizes a plastic paddle (scoop) to place a stool sample into 15 ml of Cary-Blair media for transport before being placed into a SBT with a 10 µL transfer loop prior to analysis on the BD Max System.

To use the FecalSwab Collection, Transport, and Preservation System, the operator transfers fecal material from an unpreserved stool specimen to the vial of FecalSwab transport medium using the nylon flocked specimen collection swab. The FecalSwab transport medium tube is filled with 2 ml of a semi-solid modified Cary-Blair medium that is designed to maintain the viability of enteric pathogenic bacteria during transit to the testing laboratory. Last, before analysis on the BD MAX system. samples collected/stored with the FecalSwab system are vortexed and then pipetted (50 µl) into a BD MAX™ sample buffer tube (SBT).

Once specimens (Unpreserved, Cary-Blair, or FecalSwab Cary-Blair) are placed into a BD MAX SBT, the test principles are as described in K140111 and K170308. For all specimen types the SBTs are vortexed and then loaded into the BD MAX system along with the Unitized Reagent Strips, Master Mix, Extraction Tubes, and PCR Cartridges. No further operator intervention is necessary, and the following automated procedures occur. The microbial cells are lysed and DNA

8

is extracted using a combination of lytic and extraction reagents at elevated temperatures. Nucleic acids released from the target organisms are captured on magnetic affinity beads. The beads, together with the bound nucleic acids, are washed and the nucleic acids are eluted by a combination of heat and pH. Eluted DNA is neutralized and transferred to the Master Mix Tube to rehydrate the PCR reagents. After reconstitution, the BD MAX System dispenses a fixed volume of PCR-ready solution containing the extracted nucleic acids into the PCR Cartridge. Microvalves in the cartridge are sealed by the system prior to initiating PCR in order to contain the amplification mixture and thus prevent evaporation and contamination.

The amplified DNA targets are detected using hydrolysis (TaqMan®) probes, labeled at one end with a fluorescent reporter dye (fluorophore), and at the other end, with a quencher moiety. Probes labeled with different fluorophores are used to detect the target analytes in different optical channels of the BD MAX System. The probes are used to detect amplicons for enteric bacterial targets and the Sample Processing Control in five different optical channels of the BD MAX System. When the probes are in their native state, the fluorescence of the fluorophore is quenched due to its proximity to the quencher. However, in the presence of target DNA, the probes hybridize to their complementary sequences and are hydrolyzed by the 5'-3' exonuclease activity of the DNA polymerase as it synthesizes the nascent strand along the DNA template. As a result, the fluorophores are separated from the quencher molecules and fluorescence is emitted. The amount of fluorescence detected in the optical channels used for the BD MAX™ Enteric Bacterial Panel and BD MAX™ Extended Enteric Bacterial Panel assays are directly proportional to the quantity of the corresponding probe that is hydrolyzed. The BD MAX System monitors these signals at each cycle of the PCR and interprets the data at the end of the reaction to provide qualitative test results for each analyte (i.e., positive or negative). The assay includes a Sample Processing Control, which monitors the integrity of the reagents as well as the process steps involved in DNA extraction, amplification and detection, and checks for the presence of potential assay inhibitor.

| Intended Use | The BD MAX™ Enteric Bacterial Panel performed on the BD MAX™ System is an
automated in vitro diagnostic test for the direct qualitative detection and differentiation
of enteric bacterial pathogens. The BD MAX™ Enteric Bacterial Panel detects nucleic
acids from:
• Salmonella spp.
• Campylobacter spp. (jejuni and coli)
• Shigella spp. / Enteroinvasive E. coli (EIEC)
• Shiga toxin 1 ( stxl ) / Shiga toxin 2 ( stx2 ) genes (found in Shiga toxin-producing E.
coli [STEC]) as well as Shigella dysenteriae , which can possess a Shiga toxin gene
( stx ) that is identical to the stxl gene of STEC.

Testing is performed on unpreserved soft to diarrheal stool specimens or Cary-Blair
preserved stool specimens from symptomatic patients with suspected acute
gastroenteritis, enteritis or colitis. The test is performed directly on the specimen,
utilizing real-time polymerase chain reaction (PCR) for the amplification of SpaO , a
Campylobacter specific tuf gene sequence, ipaH and stx1/stx2 . The test utilizes
fluorogenic sequence-specific hybridization probes for detection of the amplified
DNA.

This test is intended for use, in conjunction with clinical presentation, laboratory
findings, and epidemiological information, as an aid in the differential diagnosis of
Salmonella, Shigella/EIEC, Campylobacter and Shiga toxin-producing E. coli (STEC)
infections. Results of this test should not be used as the sole basis for diagnosis,
treatment, or other patient management decisions. Positive results do not rule out co-
infection with other organisms that are not detected by this test, and may not be the
sole or definitive cause of patient illness. Negative results in the setting of clinical
illness compatible with gastroenteritis may be due to infection by pathogens that are
not detected by this test or non-infectious causes such as ulcerative colitis, irritable
bowel syndrome, or Crohn's disease. | Same |

Performance Evaluation

Four studies were conducted to demonstrate the substantial equivalence between the current predicate specimen collection (Cary-Blair) and the additional specimen collection (FecalSwab) for use in the BD MAX™ Enteric Bacterial Panel and BD MAX™ Extended Enteric Bacterial Panel assays:

  • Confirmation of equivalent analytical sensitivity with the Copan FecalSwabTM . preserved stool specimen (FecalSwab) compared to the BD MAX™ Enteric Bacterial Panel and BD MAX™ Extended Enteric Bacterial Panel from a Cary-Blair Para-Pak® stool sample was performed by the limiting dilution LoD model. Acceptable performance was demonstrated when the detection break points between the FecalSwab and Cary-Blair Para-Pak® specimen types were within one five-fold dilution of each other. Break point is defined as the highest concentration where the positivity rate is Campylobacter spp. PPA and NPA of the BD MAXTM Enteric | |
