Why Autoimmune Diseases Are So Frequently Misdiagnosed

Autoimmune diseases are conditions where the body’s immune system mistakenly attacks its own healthy cells and tissues. Common autoimmune conditions include rheumatoid arthritis, systemic lupus erythematosus, Crohn’s disease, multiple sclerosis, scleroderma, celiac disease, Graves’ disease, and Type 1 diabetes. Each of these conditions can look like something else entirely in the early stages, which is exactly why misdiagnosis happens so often.

Research published in a peer-reviewed study found that the mean time to diagnosis from first experiencing symptoms was nearly seven years, and 76% of patients reported at least one misdiagnosis for symptoms later attributed to their autoimmune disease. That is not just a medical inconvenience. That is years of wrong treatments, worsening organ damage, and a life put on hold.

Unlike infections or injuries, autoimmune conditions do not always show clear or consistent signs. Symptoms can come and go, making it harder for doctors to identify patterns early. Fatigue, joint pain, and brain fog are common symptoms across many autoimmune conditions, but these same symptoms also appear in other health issues, such as stress or hormonal imbalances.

The problem runs deeper than symptom overlap. A gap of misunderstanding and miscommunication is often experienced between clinicians and patients, leading to autoimmune diseases such as lupus and vasculitis being wrongly diagnosed as psychiatric or psychosomatic conditions. Patients in Chicago and across Illinois are told their symptoms are “in their head,” when in reality they are facing a serious, treatable autoimmune condition. That kind of dismissal is not just harmful. In some cases, it is negligent.

Conditions like lupus are particularly prone to error. The median delay from the first symptom to diagnosis in systemic lupus erythematosus (SLE) is 47 months. The physical consequences of delayed diagnosis and misdiagnosis of SLE are significant, with studies showing that delays can lead to increased organ damage, poorer health outcomes, and increased morbidity and mortality. When a doctor fails to order the right tests or connect the right symptoms, patients pay the price with their health.

When Autoimmune Misdiagnosis Becomes Medical Malpractice in Illinois

Not every wrong diagnosis is malpractice. Autoimmune diseases are genuinely difficult to identify, and a single diagnostic error does not automatically mean a doctor was negligent. Medical malpractice occurs when a healthcare provider fails to meet the standard of care, meaning the level of skill and attention that a reasonably competent doctor in the same specialty would have provided under the same circumstances.

In Illinois, a medical malpractice claim based on autoimmune misdiagnosis must establish four things. First, the doctor owed the patient a duty of care. Second, the doctor breached that duty by failing to meet the accepted standard. Third, that breach directly caused harm. Fourth, the patient suffered actual damages as a result. All four elements must be present for a claim to succeed.

What does a breach look like in these cases? Common examples include failing to order standard autoimmune blood panels (such as ANA, anti-dsDNA, or RF tests) when symptoms clearly pointed in that direction, dismissing recurring symptoms without specialist referral, misreading lab results, or diagnosing a patient with a condition like fibromyalgia, depression, or anxiety without ruling out autoimmune causes. A abogado de negligencias médicas can review your records to determine whether your doctor’s choices fell below that standard.

Misdiagnosis can also take the form of treating the wrong condition entirely. A patient with lupus who is treated only for rosacea, or a patient with multiple sclerosis who is told they have anxiety, may suffer irreversible neurological or organ damage during the delay. When that harm is traceable to a doctor’s failure to follow accepted diagnostic protocols, Illinois law allows the patient to seek compensation.

It is also worth noting that multiple parties can be responsible. A primary care physician, a specialist, a hospital, or a laboratory may all share fault. Under the abogado de negligencia médica framework of Illinois law, specifically under 735 ILCS 5/2-1117, any defendant found to be at least 25% at fault is jointly and severally liable for all damages, meaning they can be held responsible for the full amount of a patient’s losses, not just a proportional share.

Illinois Legal Requirements for Filing an Autoimmune Misdiagnosis Claim

Illinois has specific procedural rules that apply to every medical malpractice case, including those involving autoimmune misdiagnosis. Understanding these rules before you file is essential, because missing even one requirement can get your case dismissed before it ever reaches a jury.

The most important procedural rule is found in 735 ILCS 5/2-622, the Healing Art Malpractice statute. This law requires that before a medical malpractice complaint is filed, the plaintiff’s attorney must attach an affidavit to the complaint stating that a qualified health professional has reviewed the case. That reviewing professional must have practiced or taught in the same area of medicine within the last six years, must be knowledgeable in the relevant issues, and must have determined in a written report that there is a reasonable and meritorious basis for the claim. This is not a formality. Courts take this requirement seriously, and failing to comply can result in dismissal.

The deadline for filing is governed by 735 ILCS 5/13-212. An Illinois medical malpractice action generally must be brought within two years after the claimant knew, or through reasonable diligence should have known, of the injury or death for which damages are sought. In most cases, the deadline is two years from when the patient knew or reasonably should have known of the injury and its connection to medical care, but there is usually a four-year outside limit from the act or omission.

In autoimmune misdiagnosis cases, the discovery rule matters greatly. The Illinois Supreme Court in Moon v. Rhode (2016 IL 119572) confirmed that discovery requires dual knowledge. Awareness of an adverse medical outcome alone is insufficient; the limitations period begins only when the plaintiff has reason to connect the injury to negligent medical care. This means that if you were told for years that your symptoms were stress-related, and you only recently learned the real diagnosis was an autoimmune disease, your two-year clock may not have started until that discovery.

Still, the four-year statute of repose under 735 ILCS 5/13-212 acts as an absolute outer limit. Illinois imposes an absolute deadline: no medical malpractice action can be brought more than four years after the date on which the alleged act or omission occurred. After four years from the date of the malpractice, claims are barred regardless of when the injury was discovered. If you suspect misdiagnosis, contact an attorney right away. Waiting can permanently close the door on your claim.

What Damages Can You Recover in an Autoimmune Misdiagnosis Case in Chicago

When a doctor’s failure to correctly diagnose an autoimmune condition causes real harm, Illinois law allows patients to seek compensation for the full range of losses they have suffered. These damages fall into two broad categories: economic damages and non-economic damages.

Economic damages cover the financial losses that can be calculated with documentation. These include past and future medical bills for the treatments you needed (and the treatments you will still need), the cost of correcting the harm caused by the wrong diagnosis, lost wages if you missed work due to worsening symptoms, and reduced earning capacity if your condition has permanently affected your ability to work. A patient who spent years receiving treatment for the wrong condition, say fibromyalgia instead of rheumatoid arthritis, may have accumulated tens of thousands of dollars in unnecessary medical costs, all of which can be part of a damages claim.

Non-economic damages cover the personal toll of the misdiagnosis. Pain and suffering, emotional distress, loss of enjoyment of life, and the psychological impact of years of uncertainty and incorrect treatment are all compensable. With a delayed diagnosis or misdiagnosis, patients may also experience increased psychological symptoms, such as depression, anxiety, and lack of trust in clinicians. Illinois does not cap non-economic damages in medical malpractice cases. The Illinois Supreme Court struck down such caps as unconstitutional, meaning a jury can award what the evidence truly supports.

In cases involving multiple defendants, Illinois law under 735 ILCS 5/2-1117 provides that all defendants are jointly and severally liable for a plaintiff’s past and future medical and medically related expenses. A defendant found to be 25% or more at fault is also jointly and severally liable for all other damages, including non-economic losses. This matters in autoimmune misdiagnosis cases, where a primary care physician, a rheumatologist, and a hospital laboratory may each bear a share of responsibility. Working with a abogado de negligencias médicas helps ensure that every responsible party is identified and held accountable.

If a loved one died because an autoimmune disease went undiagnosed or was misidentified until it was too late, the family may also pursue a wrongful death claim under the Illinois Wrongful Death Act (740 ILCS 180). Surviving spouses, children, and other dependents may recover for the grief, loss of companionship, and financial support they have lost.

FAQs About Autoimmune Disease Misdiagnosis Medical Malpractice in Chicago

How do I know if my autoimmune misdiagnosis qualifies as medical malpractice in Illinois?

A misdiagnosis becomes malpractice when your doctor failed to meet the accepted standard of care, and that failure caused you harm. This means a reasonably competent doctor in the same specialty, facing the same facts, would have ordered different tests, made a different diagnosis, or referred you to a specialist. Not every diagnostic error reaches this level, but if your symptoms clearly pointed toward an autoimmune condition and your doctor dismissed them without appropriate testing or referral, that may constitute negligence. The best way to find out is to have your medical records reviewed by an attorney who handles these cases. Call Briskman Briskman & Greenberg at (312) 222-0010 for a free consultation.

How long do I have to file an autoimmune misdiagnosis malpractice claim in Illinois?

Under 735 ILCS 5/13-212, you generally have two years from the date you knew, or reasonably should have known, that your injury was connected to a doctor’s negligent act. In autoimmune cases, this clock often starts when you receive the correct diagnosis and learn that earlier detection was possible. However, there is also a four-year statute of repose, which bars claims more than four years after the negligent act, regardless of when you discovered the error. Because these deadlines can be hard to calculate in misdiagnosis cases, you should speak with an attorney as soon as possible.

Can I sue more than one doctor or hospital for an autoimmune misdiagnosis?

Yes. In many autoimmune misdiagnosis cases, multiple providers share responsibility. A primary care physician may have failed to refer you to a rheumatologist. A laboratory may have misread your blood work. A specialist may have dismissed your symptoms without adequate testing. Under 735 ILCS 5/2-1117, Illinois law allows you to pursue claims against multiple defendants. Any defendant found to be 25% or more at fault can be held jointly and severally liable for all of your damages, including medical expenses and non-economic losses. An attorney can help identify every party whose negligence contributed to your harm.

What kinds of autoimmune diseases are most commonly misdiagnosed?

Lupus (systemic lupus erythematosus) is among the most frequently misdiagnosed autoimmune conditions, with research showing a median diagnostic delay of nearly four years. Rheumatoid arthritis, multiple sclerosis, Sjögren’s disease, and Graves’ disease are also commonly misidentified, often because their symptoms overlap with more common conditions like depression, fibromyalgia, or menopause. Conditions like Crohn’s disease and autoimmune pancreatitis can be confused with other gastrointestinal disorders. If you received a diagnosis that did not explain your symptoms, or if your condition worsened despite treatment, it is worth asking whether the right diagnosis was ever made.

Does Illinois cap the damages I can recover in an autoimmune misdiagnosis malpractice case?

No. Illinois does not cap non-economic damages in medical malpractice cases. The Illinois Supreme Court previously struck down such caps as unconstitutional. This means a jury can award compensation for pain and suffering, emotional distress, and loss of enjoyment of life based on the actual evidence in your case, without a legal ceiling. Economic damages, such as medical bills and lost wages, are also fully recoverable. The total value of your case depends on the severity of your harm, the length of the diagnostic delay, and the long-term impact on your health and quality of life.
