INSTI® COVID-19 Antibody Test

bioLytical’s new one-minute COVID-19 antibody testing kit

The World’s Fastest COVID-19 Antibody Test Kit - Now Available In Europe

The INSTI® COVID-19 rapid test kit is a single-use, visually read, rapid, flow-through in-vitro qualitative immunoassay intended for the detection of total antibodies (IgM/IgG) to SARS-CoV-2 in human venipuncture whole blood, serum and plasma.

The INSTI® COVID-19 Antibody Test is intended for use as an aid in identifying with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. Results are available in as little as 60 seconds and should be read and interpreted within 20 minutes.

What Our Customers Are Saying

DeWayne Ford
Director of HIV Education and Prevention Service

This year we were able to test 72 people in a single day. As the event promotes HIV/AIDS awareness, it’s natural that we would also offer rapid HIV testing. We want to make sure everyone knows they can get their test results in 60 seconds. It’s so much easier and more attractive for people to come and get tested if they know it’s that fast.

AID Atlanta

When testing is fast and portable, it’s so much easier to offer it there and then. Removing the barriers to access is a huge priority for us. The INSTI test kit is game-changing because it allows people to know their status so quickly.

The HIMM Project

With the last test we were using, there were some concerns about window periods and the length of time it took for the test to run. It made outreach testing too complicated. Very quickly after trying INSTI in the field, we realized that a one-minute test would be ideal for use in public spaces and it could enhance our outreach programs


The INSTI® COVID-19 Antibody Test is a one-time use, rapid, visually read, flow-through immunoassay which detects antibodies to SARS-CoV-2 using a drop of human fingerstick blood.
The INSTI® COVID-19 Antibody Test kit contains a test device, 3 solutions, lancet, pipette and alcohol swab. Unlike other COVID tests, there is no additional timing device required to complete the test as results are available immediately.
Please contact to arrange training with your local sales representative or distributor.
The INSTI® test kit has a 6-month shelf life. This shelf life will be updated/extended as further stability data becomes available. The INSTI® test kit must be stored unopened at a temperature between 2° - 30°C (35.6° - 86°F). If the storage conditions deviate from the specified temperature range, external controls must be run before administering any further tests1. It is the responsibility of each INSTI® user to establish an adequate quality assurance program to ensure the proper performance under their facilities’ locations and conditions of use. When testing is performed in an outreach setting, operators should check and record the ambient temperature throughout the duration of testing. If the testing temperature falls outside 15° - 30°C (59° - 86°F), controls should be run.
A PCR test is a molecular test that uses a nasopharyngeal swab to diagnose an active COVID-19 infection. The COVID-19 antibody test is a blood test that looks for viral antibodies. The test will reveal whether you have had a recent or previous COVID-19 infection.
COVID rapid test kits can be used to assess recent or prior infection in patients that suspect that they had COVID-19, even if they never showed symptoms or signs of illness. Antibody responses to the virus take time to develop and differ from person to person. It is recommended to wait 3-4 weeks to get tested with a COVID-19 rapid test kit.
An antibody test for COVID-19 will show whether or not you have developed antibodies to COVID-19 after exposure or vaccination. As part of your immune reaction, your body produces antibodies if you’ve been exposed to COVID-19 or vaccinated. It can take a minimum of two weeks after exposure to develop antibodies. The INSTI® COVID-19 Antibody Test Kit won’t show if you have an active infection. If you believe you’ve got COVID-19, contact your doctor or healthcare provider to get a PCR test.
False-negative results can sometimes occur. This can happen in case you get a COVID antibody test kit too soon after being exposed to the virus or vaccinated, and your body has not yet developed enough antibodies to be detected by the test. Also, some people, such as those with weakened immune systems because of medical conditions or medications, might not develop detectable levels of antibodies once exposed or vaccinated. False-positive results can also occur if the antibody test detects antibodies from other coronaviruses you may have been exposed to, like the flu virus. If you are not sure about your test results, you should contact your doctor or healthcare provider.
An antibody test can help identify individuals who have developed antibodies after exposure to SARS-CoV-2 or vaccination. However, do not use the test to verify the immunity level you have. Yet, evidence is still being collected to determine if antibodies specifically provide protective immunity against SARS-CoV-2 (COVID-19).
This test can determine whether or not you have antibodies at the time of testing. However, it is still unknown whether or not it is useful to track antibody levels over time.
Currently, nobody knows how long COVID-19 antibodies last. Some studies indicate that the antibodies stay active for 5 to 7 months after infection.
Results of COVID-19 rapid antibody tests can help determine how many people had COVID-19 and recovered, including people who didn’t have any symptoms.
