What are neutralizing antibodies?

Neutralizing antibodies or NAbs are the specific antibodies that allow your body's immune system to protect themselves against pathogens (organisms that cause disease). In COVID-19, these NAbs prevent penetration of the virus into the cell. 

Why is the neutralizing antibody test important?

It has been clearly shown and acknowledged that COVID antibodies wane over time. The level of immune protection can also vary between individuals based on pre-existing conditions and on the type of vaccine (manufacturer) given. NAbs are generated by your immune cells in response to a vaccine or to exposure. This test defines a quantitative (percentage) of NAbs present. The FDA EUA test measuring NAbs defined > 30% as positive protection against the SARS-CoV-2 virus.

Understanding your immune status and level of protection is critical in the decision-making regarding vaccine boosters, getting a vaccine, and understanding protection against different variants. It is important to understand that immune protection is not immunity. This issue has also clearly been defined by the FDA recently – “Immunization: A process by which a person becomes protected against a disease through vaccination.” Any decision making related to the results of this test should be made in consultation with your physician or health care provider.

What is the difference between an antibody test and a neutralizing antibody test?

A common misconception is that all COVID antibody tests, which are commonly available, provide the same information. This is incorrect. A standard COVID antibody test will measure all antibodies, binding and neutralizing. This will give you an idea that you have been exposed to the virus but not the level of your immune protection. This is only defined by the neutralizing antibody test.

What is an FDA EUA test?

The Emergency Use Authorization Authority allows the FDA to streamline the approval process for laboratory tests which are deemed as essential countermeasures against public health threats such as the COVID-19 pandemic.

What is a Laboratory Developed Test?

Laboratory developed tests, or LDTs, are laboratory tests that are unique or modifications of existing tests. These LDTs are developed by laboratories which have the technical expertise and follow regulatory standards and protocols (CLIA).

The FDA states that, “LDTs are important to the continued development of personalized medicine, so it is important that in vitro diagnostics are accurate so that patients and health care providers do not seek unnecessary treatments, delay needed treatments, or become exposed to inappropriate therapies.” An example of an LDT in the Comprehensive Immunity Test is the percentage of protection of against the Delta variant.

What does HIPAA compliance mean?

HIPAA is the acronym for the Heath Portability and Accountability Act of 1996 passed by The United States Congress. It is a set of rules and regulations around personal heath care information that providers of healthcare use as a part of the delivery of healthcare in all its forms. The Act sets out how healthcare providers and companies who support healthcare providers handle information, including the security required around the transmission and storage of the information as well as the administrative tools needed ensure adherence to the Rules and Regulations.
