FAQ

Answers to some frequently asked questions.

What type of test is Visby Medical COVID-19 Point of Care Test?

The Visby COVID-19 Point of Care Test is:

  • PCR
  • 30-minutes
  • instrument-free
  • single-use (disposable)
  • a molecular diagnostic test

The device utilizes RT-PCR (reverse-transcriptase polymerase chain reaction) for the qualitative detection of ribonucleic acid from the SARS-CoV-2 virus. The Visby Medical COVID-19 Point of Care Test contains all components required to carry out an assay for SARS-CoV-2 in nasopharyngeal, nasal, or mid-turbinate swabs.

What is the difference between a molecular test, an antigen test, and an antibody test?

A molecular test, such as the Visby Medical COVID-19 Point of Care Test, detects the presence of virus genetic material (SARS-CoV-2 RNA) to help identify active infection. An antigen test detects specific proteins of the SARS-CoV-2 virus. Antigen tests also help to identify an active infection, but are generally less sensitive than molecular tests. An antibody test detects the presence of SARS-CoV-2 antibodies, the body’s immune response, to the COVID-19 virus. Antibody tests help determine past infection of COVID-19, but do not detect active infections.

Who may be tested using the Visby test? Does the individual need to be symptomatic?

The Visby Medical COVID-19 Point of Care Test is authorized for use for individuals suspected of COVID-19 by their healthcare provider.

What are CLIA-Certified Laboratories and Point of Care Settings?

Under CLIA, a laboratory is defined as a facility that performs applicable testing on materials derived from the human body for the purpose of providing information for the diagnosis, prevention, or treatment of any disease or impairment of human beings.

Point of care includes settings such as physician offices, urgent care, outpatient clinics, pharmacies, and patient care settings that operate under a CLIA Certificate of Waiver, Certificate of Compliance, or Certificate of Accreditation.

What does instrument-free PCR mean?

For the person waiting for their result, instrument-free PCR means they have access to lab-quality results in under 30 minutes. The lab comes to the patient instead of the patient sample going to the lab.

For the healthcare professional, instrument-free means everything required to run a lab-grade PCR test is included within the test kit, including all of the necessary reagents and supplies. This translates to less hands-on time, no maintenance, no bottleneck or backup time, and no calibration costs.

Why choose Visby Medical’s PCR device?

Compared to the PCR instruments that exist in hospitals and laboratories today, the Visby Medical device is faster and easier to use, and it fits in the palm of your hand for portable use at the point of care.*

*Requires a CLIA Certificate of Waiver

How accurate are the results / What are your positive and negative percent agreement with lab-based PCR?

The concept of accuracy depends upon the comparator test used. The Visby Medical COVID-19 Point of Care Test has a 100% positive percent agreement, a 95.2% negative percent agreement, and a Limit of Detection (LoD) of 435 viral genome copies per swab. To best understand the performance please review our package insert for more detail.

What is a false positive? What is a false negative?

A false positive occurs when the test result incorrectly detects the presence of a virus when it is absent. A false positive can also be from the contamination or introduction of the virus/amplicon to the sample even though it is not present in the patient. A false negative is when the test fails to detect the presence of a virus even though the patient is actually positive.

How should I store the Visby device before, during, and after use?

Store the Visby Medical COVID-19 Point of Care Test in a cool and dry environment (36°F-86°F). Do not freeze. In case of refrigeration or other exposure to cold temperatures, ensure that the Visby device is allowed to come to its minimum operating temperature prior to use.

Do not remove the COVID-19 device from the foil pouch until the workspace is prepared and you are ready to run the test. When you are ready to run the test, make sure the COVID-19 device is at room temperature (66°F-82°F) on a clean, level surface, with the main label facing upward.

After use, the COVID-19 device, pastettes, and Visby Buffer should be disposed of in accordance with local regulations.

Is the Visby COVID-19 test available for home use?

No. Visby Medical received emergency use authorization (EUA) from the FDA for use in CLIA-waived settings, which includes locations in the US such as doctor’s offices, mobile labs/clinics, surgical centers, nursing homes, or any laboratory with a CLIA Certificate of Waiver.

How does Visby’s COVID-19 test compare to saliva-based tests?

Currently, all FDA EUA saliva-based tests are run on central laboratory systems (i.e. samples must be shipped to a central laboratory capable of running high complexity laboratory tests). As of March 16th, 2021, none of the approved saliva COVID-19 molecular tests are authorized by the FDA for use at point-of-care (POC) settings. Turnaround time for saliva tests is longer than 30 minutes (unlike the Visby Medical test). Existing saliva-based tests take at least three hours for results, plus additional time for transport, processing, and result reporting — the turnaround time is similar to a lab-based PCR test. The Visby Medical COVID-19 Point of Care Test is sensitive, easy-to-use, and delivers results in less than 30 minutes in a POC setting.
