importance of specimen quality.
• Use Nylon or Rayon tipped nasopharyngeal swabs for sample collection.
• Place swab into Universal Transport Medium (3 mL). Break swab shaft and cap the tube.
• Transport human respiratory samples refrigerated at 2 – 8ºC. When transporting human
respiratory samples, ensure that all applicable regulations for the transport of etiologic
agents are met.
Storing the Sample
• Wipe down the outside of each sample tube with a lint-free decontaminating wipe when
the samples are received to avoid cross contamination.
• Store the nasopharyngeal swab samples refrigerated at 2 – 8 ºC for up to 72 hours
before processing.
• For longer term storage, store the samples frozen at – 70 ºC or below.
Preparing the Sample for Testing
• [Frozen samples only] Thaw samples at room temperature and thoroughly vortex each
sample for a minimum of 5 seconds.
• [Frozen samples only] Briefly centrifuge (e.g. 5 – 10 seconds) the sample in a minicentrifuge after mixing to ensure all of the sample fluid is at the bottom of the tube.
• Open and load one sample tube at a time to avoid cross contamination from tube to tube.
Improper collection, storage, or preparation of samples may negatively impact test
results and/or lead to cross contamination.
PREPARING THE WORK AREA FOR TESTING
•

PREPARING THE RV+ REAGENTS FOR LOADING
This section provides step by step instructions for performing the Verigene Respiratory Virus
Plus Nucleic Acid Test (RV+) on the Verigene System. Note: A quick overview is provided at
the end of this document.
Preparing the Extraction Tray for Loading
The Extraction Tray is a single use plastic tray filled with reagents required for the nucleic acid
extraction portion of the assay. The tray is stored at 2 – 8 ºC.
The reagents include magnetic beads, which settle during storage. Briefly
shake the tray to resuspend the magnetic beads prior to loading. Check for
resuspension by visually inspecting the well containing the beads. Following
resuspension, tap the tray on the counter to ensure that the reagents settle to
the bottom of each well.

Preparing and Assembling the Amplification Tray for Loading
The Amplification Tray is a single-use plastic tray filled with reagents required for the amplification
o
portion of the assay. The tray is stored at – 20 C or colder.
(A) The reagents within the Amplification Tray must be adequately thawed to ensure
homogeneity during the assay. Thaw the Amplification Tray at room temperature for 10 – 30
minutes before initiating a run. Visually inspect the tray for an orange reagent which moves
when agitated in liquid form.
Note: Only thaw Amplification Trays that will be used immediately to avoid enzyme
degradation. Do not re-freeze Amplification Trays.
(B) Once thawed, mix the reagents in the amplification tray by using a vortex mixer. Set the
vortex mixer to a setting between 5 and 6 and turn it on. Gently hold the amplification tray
against the vortex mixer for 10 seconds. Tap the tray on a solid surface to ensure that the
reagents return to the bottom of each well.
(C) The Amplification Tube is also required for the amplification process. It is stored at room
temperature. Remove the cap on the Amplification Tube prior to inserting the tube into the
Amplification Tray.
Note: Always use clean gloves during Amplification Tube insertion.
(D) Push the Amplification Tube into the Amplification Tray.

(E) After thawing, visual inspection, vortex mixing, and Amplification Tube insertion, tap the tray
gently on a solid surface to ensure that the reagents return to the bottom of each well.
Once the Amplification Tray has been removed from the freezer, begin test run
in the next 10 to 30 minutes or discard.
Wear clean gloves to insert the Amplification Tube.
Save the Amplification Tube cap to re-cap the Amplification Tube after
completion of the assay.
Removing the Test Cartridge Cover
®
The Verigene Test Cartridge contains the reagents required for the identification portion of the
assay, and it also contains a barcode for identification purposes. The cartridge is shipped and
stored with a cover to prevent reagent evaporation. It is stored at 2 – 8 ºC. The user must
remove the Test Cartridge’s cover prior to loading. Hold the cartridge on the handle side with the
left hand (see illustration below), and remove the cartridge cover with the right hand by bending
the cover away from the snaps. While applying pressure with the palm of the hand, pull up on the
handle to bend the cover for removal.

Settling the Test Cartridge Reagents
The user must “settle” the reagents in the cartridge before loading into the Verigene Processor
SP. The optimal method for “settling” the reagents is to hold the Test Cartridge’s reagent
container on the side opposite the handle and tap the reagent container’s barcode with your index
finger. When tapping the cartridge, allow the force of the tapping to move the cartridge and your
right hand. The tapping is more effective when the cartridge is held in the air so that it moves
slightly.

ready for loading as described in the section below.
Note: These steps can be repeated for additional cartridges; up to 60 cartridges can be
entered into a single session.
ANALYZING RESULTS
(A) Once the Processor SP and Reader indicate that the procedure is completed, remove
the Test Cartridge. The Verigene Processor SP will display “Procedure Done” on the front
of the instrument. The Reader will have an arrow in the Test Cartridge icon when the
Processor is finished.
(B) After removing the Test Cartridge from the Processor, orient the substrate on its side and
immediately remove the reagent container from the substrate holder. Keep the substrate
holder on its side until it is inserted into the Verigene Reader. Keeping the substrate on its
side allows any residual rinse reagent to flow away from the array part of the slide while
evaporating.
(C) Leave the substrate on its side on a clean, dust-free surface until the Reader is available for
analysis. Scan the barcode, remove the tape from the substrate, and insert the substrate into
the Reader for analysis.
Substrate Holder
Keep the substrate on its side during reagent pack removal, and leave it on its
side for 30-60 seconds after removal.

INTERPRETATION OF RESULTS
The Verigene System software automatically determines the specimen results for Influenza A;
Influenza B; RSV A; RSV B; and Influenza A subtypes H1, H3, and 2009 H1N1. The test is
designed to provide a “Detected,” “Not Detected,” or “N/A” decision for each of the 7 targets
evaluated in each test sample. For example, the presence of Influenza A in a sample is
described as “Influenza A Detected” and the absence of RSV A in the same sample is described
as “RSV A Not Detected”. When Influenza A is Not Detected, the Influenza A subtype targets are
not analyzed and a “N/A” result is displayed for H1, H3, and 2009 H1N1.
An example of a detailed report can be found below. A normalized ratio of 0.85-1.00 indicates a
positive call and “Detected” is displayed alongside the virus.

Verigene RV+
Technical Bulletin
January 2011
Failure of the system, cartridge or sample to produce a test result for one or more of the targets
can produce a “No Call” result. The descriptions of possible “No Call” results can be found in the
table below. In each case, the recommended recourse is to repeat the RV+ assay using the
same sample. If the repeat test generates “Detected,” “Not Detected,” or “N/A” results for each of
the 7 targets, the results are accepted. If the repeat test provides the same decision, the sample
is inadequate for testing on the RV+. A fresh specimen should be collected and tested.
