Compared to other types of lab tests, the hsLRA™ tests are the most comprehensive and specific tests in determining and addressing the hidden causes of many common health concerns.

LRA tests are...
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:
T cell direct activation
The diagram to the right illustrates how LRA tests measure all three delayed allergy paths.
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). Antibody tests such as IgG and IgG4 (offered by Cyrex, Immuno Labs, and many other labs) 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.
