Diagnosis & Treatment:

Autoimmune Terminology To Know For Your Next Doctor's Appointment

Damiana Chiavolini, PhD December 12, 2023

While having guidance and support from your doctor is essential, taking control of your own health is important for planning and making informed decisions about your autoimmune disease. Being on board with the terms used to describe autoimmunity and specific diseases during your doctor’s appointments can help you receive the care you need as you ask questions to recognize signs and symptoms, understand the reasons behind testing, and navigate treatment options.


Understanding the meaning of basic terms can greatly boost your confidence as you discuss your autoimmune disease, potential complications, and best management strategies with your doctor.

Disease, condition:
Symptom, sign, syndrome:
Infection, inflammation:


Taking the time to become familiar with the terminology that is more specific to autoimmunity can help you understand more about disease features, diagnostic testing, available treatments, and experimental therapies.

Immune dysregulation:
Antibodies, antigens, autoantibodies, autoantigens, antigen-presenting cells:
Cytokine, Cytokine Storm:
IgE, IgG, IgM:

Autoimmune disease testing:

After a physical exam, your healthcare provider will order additional tests to diagnose your disease depending on your signs and symptoms. Terms to keep in mind include autoantibody tests, antinuclear antibody (ANA), complete blood count (CBC), C-reactive protein (CRP), enzyme-linked immunosorbent assay (ELISA), and erythrocyte sedimentation rate (ESR) (7). Take note of these terms and abbreviations and ask for more details about the ones your doctor recommends. Always ask questions about what they mean and how they work.

Some common autoimmune disease tests include:

Antinuclear antibody (ANA) test
C-Reactive Protein (CRP) test
ELISA assay
Erythrocyte sedimentation rate (ESR) test
