A troponin test can be a lifesaving tool when it is used for the right reason. The problem is what happens when it becomes routine. In today’s emergency rooms, a single lab value can hijack the visit and turn a simple story into a cardiology pipeline. That is how emergency room overtreatment starts.
This episode of the Return to Healing Podcast was sparked by an 86-year-old patient of mine who face-planted at a store. He did not have chest pain. His brain imaging was normal. But a troponin was drawn anyway, it rose, and suddenly the system acted as if the lab was the patient. Overnight admission, serial troponins, echocardiogram, stress test, cardiology consult. The man, his wishes, and his baseline health barely mattered.
If you have ever left the ER thinking, “That was a thorough evaluation,” this is the uncomfortable truth. Many times it is not thorough. It is protocol.

The myth: a troponin test is always “good information”
In this episode of the Podcast we say something that makes people uncomfortable: you can absolutely have too much information. The danger is not the data itself. The danger is data taken out of context, then treated as destiny.
Troponin is designed to help diagnose heart attack. It is not a general “how sick are you” meter. If you order it on patients who do not have a clinical picture of heart attack, you should expect false positives. Older adults often have baseline elevations. Kidney function can affect it. Trauma and stress on the body can affect it. Even endurance exercise can affect it.
That is why troponin should be a targeted test, not a fishing expedition.
The first domino: troponin without chest pain
Here is what the troponin cascade looks like in real life.
A patient comes in for a fall, fainting, weakness, dizziness, or “just not feeling right.” Someone orders a troponin because it is part of the protocol, not because the story suggests heart attack. It comes back abnormal. Now the visit is no longer about the fall or the fainting. The visit becomes “rule out heart attack.”
From there, it is almost automatic: serial troponins, cardiology consult, echocardiogram, stress testing, admission or observation. Even if the next tests are normal, the patient often leaves with new follow-up appointments and a new identity: cardiac patient.
That is emergency room overtreatment in a nutshell. The test created a problem that did not exist.
Syncope workups and protocol medicine
The same pattern shows up with syncope, the medical term for passing out. A syncope protocol can trigger layers of testing before anyone pauses to ask the obvious question: what happened right before the person went down? Were they dehydrated? Overheated? Not eating? On blood pressure meds? Standing up quickly?
A good history and a simple exam often outperform a battery of scans. But protocols do not get rewarded for thinking. They get rewarded for doing.
In this episode of the Podcast, Alan describes a Parkinson’s patient who could not urinate. The diagnosis was obvious; a distended bladder from constipation. The solution was simple; a Foley catheter. Instead, the ER ordered a CT scan and then wanted to admit him for a protocol concern that could have been handled in the moment.
This is what happens when medicine becomes an app.
The ER trifecta: troponin, BNP, and D-dimer
Alan calls it the trifecta; Troponin, BNP, D-dimer. They get ordered constantly, and one of them is often abnormal. Then the abnormal result becomes the driver of care.
This is not because ER doctors are stupid. It is because they are trapped in a system that punishes them for missing anything, and rewards them for ordering everything. But the downstream reality is still the same. A positive result triggers imaging. Imaging triggers incidental findings. Incidental findings trigger consults, referrals, and sometimes procedures that carry real risk.
This is how a busy ER becomes a pipeline, not a problem-solving space.
Incidentalomas and accidental diagnoses
One of the least discussed harms of aggressive ER testing is what it finds that does not matter. Incidentalomas are incidental findings; tiny nodules, mild abnormalities, age-related changes, “maybe this” and “maybe that.”
Once they are discovered, they rarely get ignored, even when ignoring them would be the smartest thing to do. They become follow-up scans. Specialist visits. Biopsies. Sometimes invasive tests. Sometimes complications.
A protocol that begins with “just to be safe” can end with real injury. That is the part people never factor in when they say, “More information can’t hurt.”
Why the ER feels dangerous to us
The ER can save your life when you have the right emergency. It can also harm you when it turns low-risk problems into high-intensity workups.
In the episode I share a personal example about my father. A lab value suggested fluid overload, even though he was dehydrated. The system treated the lab and not the person, and the result was catastrophic.
That is what we mean by numbers-based medicine. The body in front of you becomes secondary.
What patients can do in the ER without being difficult
You are allowed to ask questions. You are allowed to slow the cascade. A good clinician will not be threatened by questions that clarify purpose.
Try these in plain language:
- What is the test looking for and what symptom makes that diagnosis likely?
- What will change depending on the result?
- What is the downside? Including false positives and incidental findings.
- Is watchful waiting safe in your specific situation?
If a clinician cannot tell you what a test will change, that is a sign you are in protocol territory, not medical judgment.
This is not anti-medicine. It is pro-common sense.
We Can Return to Healing
A troponin test can help when the story fits a heart attack. When it is used routinely, it can start a cascade that creates fear, cost, and harm. That is emergency room overtreatment.

Troponin Test & ER FAQ
What is the troponin test?
Troponin is a blood marker used to help diagnose heart muscle injury, including heart attack, when the clinical story fits.
Can you have high troponin without a heart attack?
Yes. Troponin can rise with kidney issues, age-related changes, physical stress, trauma, and other illness. It must be interpreted with symptoms and exam, not in isolation.
What is a troponin false positive?
It is an elevated result that does not represent the diagnosis being pursued, such as heart attack. Routine ordering increases false positives, especially when pre-test suspicion is low.
What is a syncope workup?
A syncope workup is the evaluation of fainting. In many ERs it triggers a protocol pathway. The key is targeted testing based on history, exam, and risk, not automatic scans.
Why is CT imaging common after falls in older adults?
Many hospitals use automatic trauma pathways. Imaging can be appropriate in certain scenarios, but broad scanning increases incidental findings and downstream interventions.
How can I avoid emergency room overtreatment?
Ask what each test will change, ask about false positives, and make sure the plan is tied to your symptoms and story. If you feel dismissed, ask for the clinician to restate the working diagnosis in plain language.
