When a Missed Diagnosis Changes Everything
A timely and accurate diagnosis is the foundation of effective medical care. When doctors or medical providers overlook symptoms, misread test results, or fail to follow up on warning signs, patients may lose the opportunity for life-saving treatment.
Misdiagnosis and delayed diagnosis can allow serious conditions to progress unchecked. What might have been manageable or treatable in the early stages can become catastrophic once the window for intervention closes.
At McEldrew Purtell, we represent individuals and families whose lives have been altered by diagnostic errors. Our legal team works with trusted medical experts to determine what should have been recognized, what was missed, and how the failure caused preventable harm.


How Much Is Your Case Worth?

How Diagnostic Failures Happen
Diagnostic errors often occur when providers fail to recognize clear clinical indicators or do not take the necessary steps to confirm a suspected condition. In many cases, the warning signs were present but were overlooked or dismissed.
Common causes of misdiagnosis or delayed diagnosis include:
- Failure to order appropriate diagnostic testing
- Misinterpretation of imaging studies or lab results
- Ignoring patient symptoms or medical history
- Inadequate follow-up after abnormal test findings
- Failure to refer a patient to the appropriate specialist
- Communication breakdowns between providers or departments
- Rushed examinations or incomplete evaluations
Even small breakdowns in the diagnostic process can lead to devastating consequences when serious conditions are involved.
Injuries Linked to Delayed or Incorrect Diagnoses
When medical providers miss a diagnosis or identify a condition too late, the resulting harm can be severe and irreversible.
Common injuries associated with diagnostic errors include:
- Advanced or metastatic cancer that could have been treated earlier
- Stroke or brain injury from untreated vascular conditions
- Permanent neurological damage
- Organ failure or systemic infection
- Sepsis resulting from untreated infections
- Loss of limb due to delayed treatment
- Permanent disability or chronic pain
These injuries often require lifelong care, rehabilitation, and support. In the most tragic cases, the delay or misdiagnosis leads to loss of life.


Wrongful Death Caused by Diagnostic Errors
A missed diagnosis can be fatal when life-threatening conditions go untreated. Conditions such as cancer, heart attack, stroke, infection, or internal bleeding may worsen rapidly if not recognized and treated promptly.
Families are often left wondering how the outcome could have been different if the correct diagnosis had been made sooner.
Wrongful death claims may arise when medical providers fail to identify a condition that a reasonably careful provider would have recognized under the same circumstances. These cases seek accountability for the loss and help families recover compensation for financial and emotional losses.
Who May Be Responsible for a Diagnostic Failure
Diagnostic errors can involve multiple healthcare professionals and institutions. Determining responsibility requires careful investigation into every stage of the patient’s care.
Potentially liable parties may include:
- Primary care physicians
- Emergency room doctors
- Specialists
- Radiologists or pathologists who misinterpret test results
- Hospitals and healthcare systems
- Clinics or urgent care facilities
- Medical staff responsible for communication or follow-up
In many cases, liability extends beyond a single provider and involves broader system failures within a medical facility.


How We Build Misdiagnosis and Delayed Diagnosis Cases
Proving a diagnostic error requires a detailed review of the medical timeline and the decisions made by healthcare providers.
At McEldrew Purtell, our team builds these cases by:
- Securing and analyzing complete medical records
- Identifying missed symptoms, abnormal findings, or red flags
- Consulting with medical specialists and diagnostic experts
- Reviewing imaging, lab results, and pathology reports
- Evaluating the timeline of symptoms, testing, and treatment decisions
- Determining how earlier diagnosis could have changed the outcome
This approach allows us to clearly show how the diagnostic failure occurred and how it directly contributed to the injury or loss.
