COVID-19 antibody testing utilizes a serum sample to identify exposure to the SARS-CoV-2 virus, regardless of symptom presentation. The COVID-19 IgG + IgM Antibody Panel evaluates IgG and IgM reactivity separately, providing individual results for each. This may be useful for determining the current stage of infection.
This test is performed on a high-precision chemiluminescent immunoassay that has received FDA authorization under emergency use authorization (EUA).
We run our COVID-19 IgG + IgM Antibody Panel on a high-precision enzyme-amplified chemiluminescence technology (CLA) immunoassay analyzer from Diazyme Laboratories . The SARS-CoV-2 IgM/IgG CLA utilizes this highly sensitive technology to detect even very small amounts of IgM and IgG antibodies for SARS-CoV-2. It is FDA- authorized under emergency use authorization (EUA).
In a human study of COVID-19 patients, the COVID-19 IgG + IgM Antibody Panel was found to meet the following specifications for sensitivity and clinical specificity:
Once the specimen has been received by our lab, you can expect test results in 24-48 hours. 99% of results are available in 24 hours and 5% in 48 hours. You will be able to view the results via our online portal.
Antibody tests are not considered diagnostic for COVID-19. The COVID-19 Immune Response Panel measures IgM antibodies which can rise during an active infection.
If an individual is symptomatic or has been recently exposed to COVID-19 we suggest following up with a molecular diagnostic assay to rule out infection in these individuals.
Our COVID-19 IgG + IgM Antibody Panel is FDA authorized under emergency use authorization.
We use state-of-the-art, highly sensitive chemiluminescent platforms to run these tests. .

Yes. Consider combining our COVID-19 antibody and diagnostic tests if:
There is evidence that this type of test is not as accurate for children. We do not recommend using these tests for children under the age of 2, or children of any age that are currently breastfeeding.
If you have US BioTek serum kits that contain SST tubes they may be used for Antibody test collection. If your kits contain a plain red-top tube and a serum transfer tube, then the kits cannot be used for the spike protein tests.
At this time we are only able to offer our COVID-19 antibody tests to medical providers for in-clinic use.
We are a CLIA and CAP accredited medical laboratory based in Shoreline, Washington. We employ the latest laboratory technology, advanced automation, and a dedicated research team to ensure the accuracy and reproducibility of every test. We've applied 30+ years experience in laboratory science to refine and optimize the procedures we follow in our tests, resulting in more meaningful and reliable information for providers and patients.
Already have a US BioTek account? The next step is to make sure you have appropriate collection materials.
If you have SSTs on hand, you may use these (please review our instructions for collection and shipping). Alternatively, you can request collection kits from US BioTek. These are available free of charge to licensed practitioners with a US BioTek account.
Upon completion of specimen collection, complete the requisition form included in your test kit and include it in your specimen shipment. You can also complete and print our online interactive PDF form.
How to complete the requisition form:
• Print patient’s name legibly, last name first.
• Print patient’s address, age, sex, date of birth and phone number(s).
• Record specimen collection date, collection time, date specimen is shipped, and storage conditions if the specimen is not mailed immediately after collection (i.e. ambient temperature, frozen, refrigerated).
• Clearly mark the requested test panel(s).
• Sign the requisition form (must be signed by the ordering practitioner).
• Select the appropriate billing option and supply credit card information, if applicable. No other information is required when practitioner marks “bill practitioner."
