Immunological studies investigate the presence or absence of specific antibodies and proteins to establish a patient’s immune status following vaccination or exposure to certain pathogens, to determine the level of sensitivity to a wide range of allergens, or to diagnose autoimmune conditions, whereby the body wrongly identifies itself as foreign and forms autoantibodies' resulting in disease.

The comprehensive PathTROL range of independent, third-party quality controls contain analytes to control most routine Immunology assays within the laboratory setting, essential for the validation of the results found through testing.
