Serological COVID-19 Antibody Testing can identify individuals who have been exposed to the SARS-CoV-2 virus, whether they have presented symptoms or not or have had an effective immune response to vaccination. We offer comprehensive testing for IgM and IgG 
antibodies and spike protein antibodies, with three options to deliver the information your patients need based on their individual circumstances.
Each is performed using enzyme-amplified chemiluminescence technology, which features higher sensitivity than conventional ELISA or rapid lateral flow tests. We purposely selected this platform based on our 30+ years of experience in immunoassay development, and are confident it provides the most accurate results available for COVID-19 antibody testing.
We run our COVID-19 antibody tests on high-precision immunoassay analyzers that utilizes enzyme-amplified chemiluminescence technology (CLA). The SARS-CoV-2 IgM/IgG CLA utilizes this highly sensitive technique to detect even very small amounts of IgM and IgG antibodies for SARS-CoV-2. These machines are developed and manufactured in the US and offer the most accurate IgM and IgG coronavirus testing currently available.
The COVID-19 Antibody Screen has an overall specificity of 99.8% and a sensitivity of 100% at >14 days post infection.
In a human study of COVID-19 patients, the COVID-19 IgG + IgM Antibody Panel was found to have a clinical sensitivity of 95.5% and a clinical specificity of 96%.
Yes. We invite licensed healthcare providers to set up an account with us. Our services can be ordered by a healthcare provider who is authorized under his or her scope of practice to order tests and interpret results for the purposes of diagnosis and decisions regarding patient treatment.
If you do not yet have one, create a US BioTek Laboratories account. It's easy and free of charge.
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."
