It is important to obtain as much secretion as possible. Therefore, to collect a nasal swab sample, insert the sterile swab into the nostril that presents the most secretion under visual inspection. Using gentle rotation, push the swab until resistance is met at the level of the turbinates (less than one inch into the nostril). rotate the swab 8-10s for five times at least against nasal wail.

Bring tests, specimens, and/or controls to room temperature (15-30°C) before use.

• ● Wear the protection equipment. Remove the test from its sealed pouch, and place it on a clean, level surface. For best results, the assay should be performed within one hour.

Place the swab specimen into the Extraction Tube. Roll the swab at least 10 times while pressing the swab against the bottom and side of the Extraction Tube. Roll the swab head against the inside of the Extraction Tube as you remove it. Try to release as much liquid as possible. Dispose of the used swab into the Disposal Bag considered  biohazard waste.

● Put on the tube tip, then add 3 drops (100ul) of extracted sample into the sample well (S). Do not handle or move the Test Device until the test is complete and ready for reading.

• ● As the test begins to work, color will migrate across the membrane. Wait for the colored band(s) to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
• ● Dispose all assayed equipment (cassette, buffer and so on) into the Disposal Bagconsidered as biohazard.
