Quick Sheet
Add 500 μL Lysis Buffer and 200
µL sample, and mix thoroughly by
vortexing.
Transfer the mixture to the Spin
Column and centrifuge at 12,000×g
for 1 min. Add 600 μL Wash Buffer
to the Spin Column and centrifuge
at 12,000×g for 30 sec (twice).
Centrifuge at 12,000×g for 2 min
with empty column.
Add 50 μL Eluent Buffer, place it at
room temperature for 1 min, and
centrifuge at 12,000×g for 1 min.
SWAB / VTM SET
Terrabiomed Swab/VTM Set is a transport system
used for the collection and transport of clinical
samples for isolation of RNA that will be used in
SARS-CoV-2 qRT-PCR detection
Terrabiomed Swab/VTM Set
is prepared to enable obtaining
nasopharyngeal samples and
safely transporting them to the
laboratory for further analyses.
Terrabiomed Swab/VTM Set
contains a "sterile Dacron swab"
in a plastic package for collecting
the sample and a "sterile viral
transport medium" in a crack-proof
plastic tube. Samples obtained
with the swab is put in the Viral
Transport Medium (VTM). Since RNA
molecules are very susceptible to
nuclease digestion that may be
coming from degrading cells, it
is recommended to transport the
samples in an icebox and isolate
nucleic acids within 4 hours.
Storage Instructions
Unused swab/VTM sets can be
stored at room temperature.
General Safety Precautions
- Always wear masks and gloves
when working with potentially
biohazardous material.
- If spills of the contaminated
material occur, disinfect with 2.5%
hypo chloride solution.
- Pathogenic microorganisms
including Hepatitis B virus and
Human Immunodeficiency Virus
(HIV)
- Pathogenic microorganisms
including Hepatitis B virus and
Human Immunodeficiency Virus
(HIV) may be present in specimens.
Universal precautions and local
laboratory guidelines should be
followed in handling all items
contaminated with blood or
body fluids. If a tube is leaking
or is accidentally broken during
collection or transport, use the
established procedures in your
facility for dealing with infectious spills. At a minimum, universal
precautions should be employed.
- Tubes should be discarded in an
appropriate manner according to
biosafety principles.
- Never mouth pipette.
Sample Collection
1. Always wear appropriate
personal protective equipment.
2. If the patient/resident has a lot
of mucous in his/her nose, this
can interfere with the collection
of cells. Ask the patient/resident
to use a tissue to gently clean out
visible nasal mucous before a swab
is taken.
3. Seat patient in a comfortable
chair. It is best if the patient is
placed in a high-fowler's position
in bed with the back of the head
supported.
4. Enter the swab several
centimeters with a slow, steady
motion along the floor of the nose
(straight back, not up the nose)
until the posterior nasopharynx
has been reached (distance from
nostrils to the external opening of
the ear).
5. Place a finger on the tip of
the patient/ resident's nose and
depress slightly.
6. Once resistance is met (the
swab should pass into the pharynx
relatively easily), rotate the swab
several times and withdraw the
swab.
7. Break off top of the swab (it will
snap off).
8. Without touching anywhere
else, place the swab in the VTM
containing tube.
9. Remove personal protective
equipment, wash hands.
10. Ensure the specimen is labeled
and transport to the laboratory
