The VaxEffect test is highly Sensitive and Specific
in detecting antibodies produced by the COVID-19 vaccine and SARS-CoV-2 virus.
A negative result indicates
RBD and NC antibody titer below lowest detection level.
A fully vaccinated individual with a negative VaxEffect result
may benefit from an immune system evaluation, if clinically indicated.
A positive vaccine response
is measured by antibody production to only the Spike protein.
A positive result for prior exposure to SARS-CoV-2 virus
is detected by antibody production to both the Spike and Nucleocapsid viral proteins.
Patients with Immune Compromised Conditions:
The VaxEffect Test is uniquely created to detect weak but positive immune response results due to its wide dynamic range.
Including those who are fighting cancer, with diabetes, or with auto-immune issues, who may have generated a weak immune response to the vaccine.
A medical professional may ask these individuals to remain vigilant in staying safe from virus exposure and consider having a booster shot when available.
The VaxEffect Score.
Simple, Convenient, Accurate.
The VaxEffect Score is an accurate semi-quantitative measurement of your patient’s personal titer to the COVID-19 vaccine or previous exposure to the SARS-CoV-2 virus.
The VaxEffect Score is calculated by dividing the fluorescence value of an individual test result by the negative cut-off fluorescence value.
The VaxEffect Score will also allow your patients to know their level of antibody response in comparison to others who have taken the test.
Monitoring your patient’s VaxEffect Score over time with repeat testing allows you to determine COVID-19 antibody titer levels and be informed of changes to their immune response with repeat testing.
How It Works
Request free VaxEffect Sample Collection Kits
After kits arrive, please register your patients
Collect and ship patient blood sample
(following kit instructions)
Receive results from VaxEffect
within one to two business days after receipt
Your patient's individual VaxEffect Score does not currently predict immunity but does provide accurate and semi-quantitative measurement of antibody titers generated by COVID-19 vaccination or prior infection.
