Priority Lab Testing offers a series of reliable immunity test options with which patients can determine their immunity (or lack thereof) to various diseases and viruses. Depending on the disease in question, immunity can be derived by way of a vaccine, prior exposure in nature, or prenatally through antibodies acquired from our mothers. After being exposed to certain types of illnesses by way of vaccine or elsewhere, the body will learn to “fight off” future encounters. If you’re unsure about your immunization history, consider one (or more) of our immunity testing options.
