Frequently Asked Questions
About Covid-19 Testing

What Do the Test Kits Include?

- Individually wrapped testing device with desiccant
- Buffer (reagent)
- Sterile lancet
- Alcohol pad
- Capillary pipette

Can False Positives or Negatives Occur?

Yes.

The novel coronavirus (SARS-CoV-2) is new and reached global pandemic infection rates with concerning efficiency. Other corona viruses, however, are well-known and are a routine part of our lives. Please carefully evaluate the sensitivity and specificity metrics on the validation study here (hyperlink) to understand the degree to which false positives can occur due to infections by other corona viruses and false negatives can occur by testing too early after the onset of symptoms. Additionally, please note that the test measures total IgM and total IgG, so positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.

How can I use this test in my practice or facility?

The test yields a qualitative result for the presence or absence of the antibodies that may have been produced by exposure to the corona virus. Immunity is an important feature of returning to life and the medical community is only beginning to understand the relationship between total SARS/COV-2 antibody production and immunity to COVID-19. Please check to our website as additional information is published by the CDC on this topic.

What is the cost of the tests, return policy and when will I receive them?

The tests are packed in cases of 20 and are only available by the case at this time. Each individual test is priced at $49.99.

We will only allow purchasing on our website when the product is in stock. These tests are available on a first-come, first-served basis and are not refundable once delivered to your location.

If there are any changes to our estimated shipping window, we will notify you directly by e-mail and we will offer you the opportunity to cancel your order based on any changes to the delivery window.

Please contact us for bulk purchasing or a replacement for damaged or defective devices at info@preventcare.com.

How do these tests differ from what laboratories offer?

This test is not a molecular polymerase chain reaction (PCR) test that requires laboratory equipment or confirmation. Our antibody serology test is a lateral flow assay that is reasonably priced and readily available for licensed medical professionals yields immediate qualitative results without the need to send in the specimen for laboratory testing. Other laboratory tests offered on the currently offered on the market have extremely limited availability and long turn-around times.

Can other versions of corona virus cause a positive result?

This novel coronavirus (SARS-CoV-2) is new and reached global pandemic infection rates with concerning efficiency. Other corona viruses, however, are well-known and are a routine part of our lives. Please carefully evaluate the sensitivity and specificity metrics on the validated study here to understand the degree to which false positives can occur due to infections by other corona viruses.

Do commercial or federal payers reimburse for this test?

In mid April, CMS offered guidance that billing codes will be created for this test. The speed with which this happens, the relationship to the FDA governance on the topic of serology tests and the pace of adoption by both federal and commercial payers is unclear at this time. Please check back to our website for updates.
Scientific Principles Behind Our Test
The COVID-19 IgG/IgM Rapid Test Device identifies anti-SARS-CoV-2 IgG/IgM antibodies through visual interpretation of color development.

Anti-human IgG and anti-human IgM are used to identify specific antibodies in the human whole blood, serum, or plasma specimen. When specimen is added to the sample well, specific IgM and/or IgG antibodies, if present, will bind to the SARS-CoV-2 antigens conjugated to colored particles on the conjugate pad. As the specimen migrates along the strip by capillary action and interacts with reagents on the membrane, the complex will be captured by anti-human IgM and/or anti-human IgG antibodies immobilized on the test region(s). Excess colored particles are captured at the internal control region.

The presence of a red band(s) on the test region(s) indicates a positive result for the particular IgG and/or IgM antibodies, and its absence indicates a negative result. A red band at the control region (C) serves as a procedural control, indicating that membrane wicking is working.
