More than 500,000 children in the UK may have been misdiagnosed with asthma, according to research. A significant number of diagnoses rely on symptoms alone, without proper lung function tests, leading to unnecessary medications, health risks, and increased anxiety. Updated NICE guidance now stresses objective testing to confirm asthma to avoid over‑diagnosis.
Why half a million UK children may be misdiagnosed with asthma
Asthma is the most common long‑term childhood condition in the UK, with more than one million children receiving treatment. Yet, a landmark study of 652 children showed 53% were over‑diagnosed, casting doubt on the accuracy of up to 500,000 UK child diagnoses.
The issue stems from reliance on symptom‑based diagnosis—such as wheezing or coughing—without spirometry or FeNO testing, even though NICE rules require two abnormal objective tests before confirming asthma.
The cost of misdiagnosis: risks and consequences
- Unnecessary treatment: Children may take inhaled corticosteroids or bronchodilators without benefit—and face side‑effects like throat infections, muscle cramps or nausea.
- False reassurance or anxiety: A misdiagnosis can delay correct identification of other respiratory conditions, or cause undue stress for families.
- Financial impact: Asthma misdiagnosis in England alone may cost the NHS an estimated £132 million annually.
- Patient harm: Both over‑ and under‑diagnosis carry risks. Untreated asthma may lead to exacerbations and long‑term damage, while over‑treatment is avoidable harm.
What’s being done: Guidance and Improvements
New asthma guidelines from NICE are being updated to enforce structured diagnostic pathways, including spirometry, FeNO, and regular reviews—especially for younger children who may not reliably perform such tests.
NHS initiatives like diagnostic hubs aim to improve access to testing, and the Long-Term Plan supports better pathways for childhood asthma diagnosis in primary care.
Could you be eligible for compensation?
If a child was incorrectly diagnosed with asthma due to clinical negligence—for example, prescribed powerful inhalers without testing—you might be able to claim compensation.
How Much Compensation Can You Claim?
- Claims vary depending on severity of unnecessary treatment, harms endured, and any delay in diagnosing untreated conditions.
- Most medical negligence claims for misdiagnosis in children start from around £5,000–£15,000, but in more serious cases—if side‑effects, hospital admissions, or developmental impacts occurred—compensation could reach tens of thousands of pounds.
- Legal costs are typically handled on a No Win, No Fee basis.

People Also Ask
Q1: What percentage of UK children are misdiagnosed with asthma?
A: Around 50% of children diagnosed with asthma may actually not have the condition—research suggests up to 500,000 children in the UK are affected by misdiagnosis.
Q2: What tests should confirm an asthma diagnosis in children?
A: NICE requires two abnormal objective tests, such as spirometry or FeNO, not symptom-based diagnosis alone.
Q3: Can unnecessary asthma treatment cause harm?
A: Yes. Common asthma medications—even inhalers—can cause side-effects like throat infections, muscle cramps, or nausea, especially when used without need.
Q4: What should I do if I suspect my child was misdiagnosed?
A: Ask your GP for a reassessment, including objective lung tests. If you suspect negligence led to harm, contact National Claims, who can guide you through possible legal remedy.
Q5: Can misdiagnosed kids suffer late diagnosis of other diseases?
A: Yes. Misdiagnosis may delay detection of other respiratory issues—such as allergies, reflux, or dysfunctional breathing—so getting a correct diagnosis is critical.
Summary and Next Steps
Misdiagnosis of asthma in children is a widespread issue in the UK. Many GPs rely on symptoms without proper testing, exposing children to unnecessary treatments and parents to worry. New NICE guidance and NHS diagnostic hubs offer hope, but reassessment is critical—especially if your child shows no sign of worsening controlled asthma or responds poorly to inhalers.
If you believe your family has experienced a misdiagnosis, National Claims can help you get in touch with skilled solicitors who specialise in medical negligence claims. They’ll evaluate your situation and guide you toward fair compensation.
