This test identifies antibodies that develop 21 days after symptoms emerge. If you take the test too early, there’s a chance that antibodies won’t yet be identifiable, which means you’ll get a false-negative result.
For the most accurate results, wait for at least 21 days after symptoms first emerge and then take the test. The best available research shows that, when taken at the right time, this test has high sensitivity.*
Healthpath accepts no responsibility for tests that deliver a false-negative result.
* Research to determine the accuracy of the test is based on relatively small clinical studies. Patients with low immunity or other diseases that affect immune function, failure of important systemic organs, and use of drugs that suppress immune function can also lead to negative results of new coronavirus IgG. Bacterial or fungal contamination of serum specimens or reagents, or cross-contamination between reagents may cause erroneous results. Water deionized with polyester resins may inactive the horseradish peroxidase enzyme.
