Antigen Testing

One of the fastest growing sectors in the healthcare industry is diagnostics, and, by extension, immune system function and testing. Like your automobile, you perform preventative maintenance to promote longevity and safety, but you must know what you are working with. As the premier hub for all items testing, Newtropin provides access to a global network of diverse testing resources.

Antigen testing analyzes bodily fluids for certain markers of a disease, e.g., specific proteins in the virus. An antigen is a foreign substance that generates an immune response, e.g., the production of antibodies. When a test detects presence of these protective proteins, healthcare providers have greater abilities to diagnose a specific disease and swiftly prescribe a treatment protocol. They are minimally invasive and produce results in less than an hour.

Several tests have evolved as beneficial tools for healthcare providers to manage symptoms associated with various diseases. Two are the IgG and IgM, respectively, described below.

Immunoglobulin G (IgG) testing. IgG is the most common antibody present in blood and other bodily fluids. It serves as a memory system in immune support, in other words remembering which antigens your body has been exposed to. They are effective in identifying bacterial and viral infections. The sophistication comes in the ability of these tests to subclass, e.g., although total IgG levels may be normal, a particular class of IgG could be unsettled and potentially indicate an underlying condition.

Immunoglobulin M (IgM) testing. IgM antibodies serve as your body’s first responder and primary line of defense against infection. These are the largest antibodies and are produced when the body detects a new infection. They function as short-term protectors while the immune system bolsters its defenses and produces other antibodies.

Upon infection, the body customizes production of specific antibodies tailored to fight those germs. Based upon advanced databases and mapping, healthcare providers can diagnose several types of health conditions that impact your immune system, e.g., autoimmune, certain cancers, chronic, and genetic diseases.


Examples of specific tests we offer include, but are not limited to, covid, flu, mononucleosis, pregnancy, sexually transmitted infections (STIs), strep throat, and if we do not carry it, we are able to access it. Most are performed with blood from a simple to use finger stick application.

Two types of testing applications are available depending on the end user’s preference.

Point of care. An approved site where medical care is administered or received, e.g., physician’s office. This scenario is most popular and where the patient tests on-site and can receive practitioner feedback on results in as little as an hour.

OTC- Over the counter testing applications are tests administered for home use and provide instructions for interpreting instant results or for submission to a laboratory.
