Convenient 4-in-1 viral testing

Designed to be non-invasive and easy to self-administer, the Ecotest RSV + ABC Test Pen’s patented two-step design streamlines the process of testing for common seasonal viruses (SARS-CoV-2, Influenza A, Influenza B, and RSV). Test by swabbing your nose, then placing the pen into its buffer cap, and reading results in 15 minutes. No need for extra components, or mixing reagents: it’s as easy as that.

Two-step procedure

STEP 1. Remove the protector and insert the nasal collector into a nostril. Rotate the collector 5 times against the nasal wall. Repeat in other nostril.

STEP 2. Place the test device vertically into the tube with the extraction buffer. Ensure the top of the base aligns to the middle of the supporting line.

NOTE: Wait 15 minutes, then check your results. Do not read results after 30 minutes, as they will be invalid.

More details

Made for convenience

Our pens are designed to be used in scenarios that don't allow for the easy mixing of reagents or buffer solutions. This makes it ideal for use in locations like schools, workplaces, day-cares, or hospitals, where it may be hard or inconvenient to perform a cassette style test. Just as quick and accurate as other RATs; but an easier, more comfortable user experience.

Summary of use

The COVID-19 & Influenza A+B & RSV Antigen Nasal Test Kit is an in-vitro immunoassay intended for the qualitative detection of antigens in nasal swab specimens from patients with COVID-19, and/or RSV (within first 7 days of symptom onset), and/or Influenza A+B (within first 4 days of symptom onset). This test doesn't discriminate between SARS-coronavirus and SARS-CoV-2 (COVID-19).

Precautions for use

The test is intended for point-of-care use; and not intended for home testing (or self-testing). It obtains a preliminary result only, to aid diagnosis of COVID-19, Influenza A+B, and RSV. Please note that negative results do not preclude viral infections—test results should not be the sole basis for treatment or other management decisions.
