COVID-19 antibody testing explained

TL;DR

Antibody testing for COVID-19 is not a reliable way to modify behavior or provide immunity guarantees at this time.

Key Insights

• 👣 Antibody tests are being used to track the spread of COVID-19 and determine who has been infected.
• 🏆 Positive antibody tests do not necessarily mean individuals are protected or immune to the virus.
• 🏆 The accuracy of antibody tests varies, and not all tests are created equally.
• 🏆 Confirmatory testing is recommended after a positive antibody test to ensure accuracy.
• 🥡 It takes time for the immune system to develop a response, so early testing may result in false negatives.
• 🔨 Antibody tests should be viewed as research tools rather than clinical tools for predicting outcomes.
• 🔬 The science behind antibody testing and immunity is still evolving.

Questions & Answers

Q: Can a positive antibody test allow someone to forgo wearing a mask or return to work?

No, a positive antibody test does not guarantee immunity or the ability to modify behavior. More research is needed to understand the level and duration of protection.

Q: How accurate are antibody tests?

The accuracy of antibody tests varies. Laboratory tests sent off for analysis tend to have better performance characteristics, but they are not perfect. False positives and negatives can still occur.

Q: Are all antibody tests the same?

No, there are different types of antibody tests. Rapid tests provide quick and cheap results, while laboratory tests require a blood draw and provide more accuracy.

Q: Should individuals get confirmatory testing after a positive antibody test?

Yes, it is recommended to undergo confirmatory testing with a different antibody test or a test that looks for a different viral antigen to guard against false positives.

Summary & Key Takeaways

• Antibody tests are being investigated as a potential way to determine if individuals have been infected with COVID-19, but they cannot be used to modify behavior.

• There are two types of tests: virology tests that detect the virus itself and antibody tests that detect the body's response to the virus.

• Antibody tests are not foolproof and require confirmatory testing due to the potential for false positives or negatives.
