Lymphocyte Response Assay (LRA)

Today, at least one out of every six Americans, or 40 million people in the United States, suffer from one or more of the autoimmune and immune dysfunction diseases. In response, chronically ill Americans spend over $300 billion per year directly for autoimmune syndrome treatments that often do not reduce their suffering or improve their health. LRA testing allows our physicians to quickly and precisely determine the hidden causes of many chronic conditions and help patients find sustained relief. By looking directly at lymphocytes the LRA detects all 3 types of delayed food and chemical hypersensitivities to as many as 504 items.

LRA Testing

Compared to other types of lab tests, the hsLRA™ tests are the most comprehensive & specific tests in determining and addressing the hidden causes of many common health concerns. Revolutionary blood tests that directly analyze lymphocytes, the body’s long lived, memory-carrying white blood cells that indicate health and disease in the body. The only tests that simultaneously measure all three types of delayed sensitivity reactions through lymphocyte activation:

  • Reactive antibody (IgA, IgM, and IgG)
  • Immune complexes
  • T cell direct activation

Ex vivo tests that analyze the lymphocytes’ response to foreign invaders under controlled laboratory conditions as they react in the bloodstream, providing highly accurate information about your delayed allergies.

Functional tests that detect only symptom-provoking lymphocyte reactions, not merely the presence and amount of antibodies (which can be protective or symptom-provoking). This distinction is clinically important and can only be made by a functional, cell response assay.

More reliable and comprehensive than other tests of delayed food and chemical sensitivities (Antibody, particle size, mediator release). Many antibody tests such as IgG and IgG4 are nonfunctional tests, looking at only one delayed pathway – not a complete picture of the immune system.  LRA tests also test the most items, as many as 504.

Who Can Benefit

Chronic autoimmune, immune dysfunction, and inflammatory problems deserve attention to their cause. LRA by ELISA/ACT™ (LRA) tests and interpretive treatment plans can be the key to unlocking the mystery of chronic illness. The LRA program is designed to help people suffering from the autoimmune variants or immune dysfunction symptoms and conditions.
