Failure to Order Tests Claims 2025: Missed Diagnoses from Skipped Workups

## When Not Testing Is Negligence

Many diagnoses depend on ordering the right test at the right time. A failure to order tests claim arises when a provider should have ordered a diagnostic study, given the patient's symptoms and presentation, but did not, and that omission allowed a serious condition to go undiagnosed and untreated. This is a common pathway to a missed cancer, missed infection, or missed cardiac event.

This guide explains when skipping a test crosses into malpractice.

The Standard: Reasonable Workup

A provider is not required to order every conceivable test. The standard of care requires a reasonable workup based on the patient's symptoms, history, and risk factors. The question is whether a competent provider, faced with the same presentation, would have ordered the test. Examples of breaches include:

1. **Not ordering imaging** for symptoms that clearly warranted it, such as a CT for stroke-like symptoms.
2. **Not ordering cardiac tests** for chest pain in an at-risk patient.
3. **Skipping cancer screening or follow-up** for an abnormal finding or high-risk history.
4. **Not ordering cultures** for signs of serious infection.
5. **Failing to repeat a test** that was inconclusive but concerning.

The Follow-Up Failure Cousin

Closely related is the failure to follow up on a test that was ordered. A test ordered but never reviewed, or an abnormal result that no one acted on, is just as harmful as never ordering it. The chart may show an abnormal result that was filed without action, a frequent and provable failure.

Proving Causation

As with all diagnostic claims, causation is the battleground. You must show that the missing test would have revealed the condition and that earlier diagnosis would have changed the outcome. Evidence includes:

• **The symptoms documented** at the visit, showing the test was indicated.
• **The eventual test** that finally revealed the condition.
• **The progression** of the disease during the delay.
• **Expert testimony** that the test should have been ordered and would have led to earlier treatment.
• **Specialist testimony** on how the outcome would have differed.

Realistic Value Ranges

A failure causing a recoverable delay may settle for $75,000 to $250,000. A skipped test that allowed a cancer to advance a stage or an infection to become septic often reaches $500,000 to $2 million. Death cases are valued under wrongful death law.

Step-by-Step Action Plan

Step one: Gather records of the visit where the test should have been ordered.

Step two: Obtain the later test that revealed the condition.

Step three: Document the symptoms you reported that should have triggered the workup.

Step four: Establish the timeline and the progression during the delay.

Step five: Consult a malpractice attorney who can retain the right specialist expert.

Frequently Asked Questions

Doctors cannot test for everything. Isn't that fair? Yes, and that is the defense. You must show a reasonable provider would have ordered this specific test given your presentation.

What if the test was ordered but ignored? That is the closely related failure-to-follow-up claim, often even stronger because the abnormal result is in the chart.

How do I prove the test would have found it? Through the later test that did find it, plus expert testimony that it would have shown the condition earlier.

Does a normal-looking visit defeat my claim? Not if the documented symptoms should have prompted further testing under the standard of care.
