Operation
01. Insert the cotton swab into a nostril gently. Insert the tip of the cotton swab 2-4 cm (for children is 1-2 cm) until resistance is felt.
02. Swirl the cotton swab along the nasal mucosa 5 times within 7-10 seconds to ensure that both mucus and cells are absorbed.
03. Dip the head of the cotton swab into the diluent after taking the sample from the nose.
04. Squeeze the sample tube with a cotton swab 10-15 times to mix evenly so that the wall of the sample tube touches the cotton swab.
05. Keep it upright for 1 minute to keep as much sample material as possible in the diluent. Discard the cotton swab. Place the dropper on the test tube.
TEST PROCEDURE
06. Add the sample as follows. Place a clean dropper on the sample tube. Invert the sample tube so that it is perpendicular to the sample hole (S).Add 3 DROPS of the sample into each sample hole.
07. Set the timer for 15 MINUTES.
08. Read the result after 15 MINUTES
INTERPRETATION
POSITIVE: Two colored lines appear on the membrane. One line appears in the control region (C) and the other line appears in the test
NEGATIVE: Only one colored line appears in the control region (C). No apparent colored line appears in the test region (T).
INVALID: Control line fails to appear.
CAUTION
1. The color intensity in the test region (T) may vary depending on the concentration of virus proteins present in the nasal mucus sample. Therefore, any color in the test region should be considered positive. It should be noted that this is only a qualitative test and cannot determine the concentration of viral proteins in the nasal mucus sample.
2. Insufficient sample volume, improper procedure or expired tests are the most likely reasons why the control line does not appear.
