Flowflex Manuals & User Guides

Flowflex is a globally recognized brand in rapid diagnostic testing, best known for its user-friendly at-home antigen tests. Manufactured by ACON Laboratories, Inc., Flowflex products are designed to provide individuals with fast, reliable, and accessible health screening solutions. The brand achieved widespread prominence during the global pandemic with its SARS-CoV-2 Antigen Home Test, which received FDA Emergency Use Authorization (EUA) for its high accuracy and ease of use.

Beyond COVID-19, the Flowflex product line has expanded to include multiplex tests that can simultaneously detect and differentiate between COVID-19, Influenza A/B, and Respiratory Syncytial Virus (RSV) using a single nasal swab. These diagnostic tools are an essential resource for families, schools, and workplaces to manage respiratory health.

• How do I read the results of the Flowflex COVID-19 Home Test?

  A positive result is indicated by two colored lines: one in the Control (C) region and one in the Test (T) region, even if the T line is faint. A negative result shows only the Control (C) line. If no Control line appears, the result is invalid.

• What should I do if my test result is invalid?

  An invalid result means the test did not function correctly, often due to insufficient sample volume or incorrect procedure. You must re-test using a new test cassette and a fresh sample.

• Is the Flowflex test suitable for children?

  Yes, the test is authorized for self-collection by individuals aged 14 years and older. For children aged 2 to 13 years, an adult should collect the sample and perform the test.

• Does a negative result guarantee I do not have COVID-19?

  No. Negative results are presumptive and do not rule out infection. If you have symptoms or high suspicion of infection, the FDA recommends serial testing (testing again 48 hours later) or confirming with a molecular lab test.
