Description
Lateral movement immunochromatographic assay that adopted twin coloration system.
For the qualitative detection of SARS-CoV-2 antigen from nasopharyngeal swab specimen.
The check incorporates colloid gold conjugate pad and a membrane strip pre-coated with antibodies particular to SARS-CoV-2 antigen on the check traces (T).
A visual black band (antibody-antigen-antibody gold conjugate refined) seems on the check traces (T) If SARS-CoV-2 antigen is current contained in the specimen.
The administration line (C) reveals that check is carried out appropriately.
Evaluated with panel specimen (n = 75) by PCR
Sensitivity: 90,2 %
Specificity: 100 %
VITROS SARS CoV2 antigen assay – Procedural Steps: –
Stage 1: Nasopharyngeal swab specimen assortment:
1. Buy a nasopharyngeal swab specimen by inserting the sterile swab into the nostril.
2. Push the sterile swab till resistance is met on the stage of the turbinate.
3. Rotate the sterile swab quite a few occasions in path of the nasopharyngeal wall & go away contained in the place for
10 seconds to saturate the swab tip.
4. Take away the swab from the nostril fastidiously.
5. Place the swab specimen into the viral transport medium buffer tube and shut the tube tightly.
6. Transport the swab pattern in VTM to the laboratory in a chilly chain.
7. The pattern might probably be saved in Room temperature (Beneath 30◦C) for as quite a bit as 24 hrs from the time of
pattern assortment or at 2 – 8◦C for as quite a bit as 48 hrs from the time of pattern assortment.

Stage 2: Pattern preparation for testing:
1. Pattern preparation should be carried out in BSL-2 stage cupboard contained in the Laboratory.
2. Combine the swab specimen in VTM tube correctly (vortex roughly 3-5 seconds).
3. Change 100 μL VITROS SARS-CoV-2 Antigen Extraction Buffer correct proper right into a labelled new pattern tube.
4. Add 400 μL viral pattern to the above tube (to take care of 1:Four ratio of extraction buffer: pattern)
5. Combine correctly (Cap/Plug the pattern tube and vortex roughly 3-5 seconds).
