Positive FIT Test but No Follow-Up Colonoscopy

A FIT, or fecal immunochemical test, is a stool test that looks for traces of blood you can’t see. Many people do it at home with a kit from their doctor, mail it to a lab, and wait for a result. It’s one of the standard ways to screen for colorectal cancer, usually repeated every year.

A positive result does not mean you have cancer. Blood in the stool can come from hemorrhoids, polyps, ulcers, inflammation, or small tears. But it can also be the first sign of a precancerous polyp or an early tumor, and the test can’t tell those apart.

Only a colonoscopy can. That’s why a positive FIT doesn’t end the screening process. It’s the point where the process is supposed to continue.

Is a Colonoscopy Required After a Positive FIT?

Yes. The American Cancer Society’s guideline states that all positive results on non-colonoscopy screening tests should be followed up with timely colonoscopy. Major gastroenterology groups treat that colonoscopy as part of the screening itself, not an optional extra. A program that stops at a positive result hasn’t done its job.

Repeating the stool test is not a substitute. A negative second FIT doesn’t cancel the first positive one. The same applies to a positive FIT in someone who had a colonoscopy a few years earlier, because lesions can be missed or develop between exams.

Our page on colon and rectal cancer screening protocols explains how FIT fits alongside the other screening options.

How Long Is Too Long to Wait?

The best evidence comes from Kaiser Permanente. Researchers there followed 70,124 people with a positive FIT. Compared with people who had a colonoscopy within a month, those who waited 10 to 12 months had a 48% higher risk of colorectal cancer and nearly twice the risk of advanced-stage disease.

Waiting more than a year more than tripled the risk of advanced disease. The study found no significant increase for colonoscopies done within nine months, but its accompanying editorial put it simply: sooner is probably better.

A polyp removed during colonoscopy can stop cancer before it starts. A small cancer found early often needs far less treatment. Left alone, the same problem can spread to lymph nodes or the liver and require major surgery, chemotherapy, or radiation.

Our page on colon and rectal cancer early detection explains why timing changes outcomes so sharply.

How a Positive FIT Result Gets Lost

Rarely does anyone decide to ignore a positive result. It falls through a gap between the lab, the primary care office, the specialist, and the patient. The common patterns are:

• No one reviews the result. The lab sends it to the ordering practice, and it’s filed without a clinician seeing it.

• It goes only to the portal. The result is posted online with no phone call, and the patient never logs in or doesn’t understand it.

• It gets explained away. The doctor says it’s probably hemorrhoids and orders nothing further.

• The referral goes nowhere. A gastroenterology referral is placed, but no one confirms an appointment was made, and the patient assumes someone will call.

• The wrong test is repeated. A second FIT is ordered instead of a colonoscopy.

Cost Shouldn’t Be the Reason It Didn’t Happen

In New York, the Department of Financial Services says most non-grandfathered policies must cover a follow-up colonoscopy with no cost-sharing when an at-home stool test is positive. That includes related services such as anesthesia and polyp removal.

These protections don’t apply to self-funded employer plans or grandfathered plans, so check with your insurer if you aren’t sure which kind you have.

Can You Sue for a Missed Follow-Up After a Positive FIT?

In some situations, yes. Failing to follow up on an abnormal screening result can support a medical malpractice claim for delayed diagnosis.

A New York claim generally requires two things.

First, the provider departed from accepted standards of care. Failing to act on a positive FIT, failing to refer for colonoscopy, failing to tell the patient, or ordering a repeat stool test instead are the lapses most often examined.

Second, the departure was a substantial factor in causing injury. Usually that means showing the delay let the cancer advance to a later stage, required harsher treatment, or reduced the chance of a better outcome.

Some cancers would have had the same outcome with perfect care. Before a lawsuit can be filed, New York requires a certificate of merit confirming that the case was reviewed with a qualified physician.

Who Can Be Held Responsible?

It depends on where the breakdown happened:

• The ordering doctor or primary care practice, if it failed to review the result, tell the patient, or place a referral

• A medical group, clinic, or hospital, if the failure was systemic, such as having no process for tracking abnormal results

• A gastroenterology practice, if it received the referral and never scheduled the patient

• A laboratory, if the result was never properly reported

Several of these can share responsibility, which is why the full record from each provider matters.

New York’s Filing Deadlines

Under CPLR 214-a, as amended by Lavern’s Law, a claim for negligent failure to diagnose cancer generally must be filed within two years and six months. The clock runs from the later of two dates:

• When you knew or reasonably should have known of the error and the harm it caused

• The end of continuous treatment for the same condition

There is an outer limit of seven years from the negligent act or omission.

Public hospitals, including NYC Health + Hospitals, follow much shorter rules. A notice of claim generally must be served within 90 days.

The lawsuit itself generally must be filed within one year and 90 days. Federally funded community health centers follow a separate federal claims process with its own deadline. If a family member has died, a wrongful death claim generally must be filed within two years of the date of death.

If You Had a Positive FIT and Never Got a Colonoscopy

Your health comes first. Call your doctor, say you had a positive FIT that was never followed up, and ask for a colonoscopy. If you were told it was “probably hemorrhoids” and nothing else happened, ask anyway.

If you have rectal bleeding, a change in bowel habits, unexplained weight loss, or ongoing fatigue, raise it now rather than waiting for an appointment.

Our guide to colon and rectal cancer signs and symptoms lists what to watch for, and our page on how colorectal cancer is diagnosed explains the workup.

Then protect the paper trail:

• The lab report showing the positive result and its date

• Portal messages, letters, and voicemails

• Notes on what you were told, and by whom

• Your full records from each provider, including anything showing whether the result was reviewed, a referral was placed, or anyone tried to contact you

If you were later diagnosed, add the pathology, staging, and treatment records. Then build a simple timeline: the date of the positive FIT, the date of the colonoscopy, and the date of diagnosis.

Frequently Asked Questions

What happens if a positive FIT test is not followed up?

Any polyp or early cancer that caused the bleeding goes undiagnosed and can keep growing. A Kaiser Permanente study of more than 70,000 people found that waiting 10 to 12 months for a colonoscopy after a positive FIT raised colorectal cancer risk by 48% and nearly doubled the risk of advanced-stage disease, compared with prompt follow-up.

How soon should you get a colonoscopy after a positive FIT?

As soon as reasonably possible. Guidelines call for timely colonoscopy after any positive stool test, and many programs aim for within a few weeks. Research found cancer risk rose significantly once the wait reached 10 months or longer. If you haven’t been scheduled, call your doctor rather than waiting to be contacted.

Can a repeat FIT replace a colonoscopy after a positive result?

No. A positive FIT should be followed by a colonoscopy, not another stool test. A negative second FIT doesn’t cancel the first result, because polyps and tumors bleed on and off. A doctor who orders a repeat FIT instead of a colonoscopy after a positive result may be departing from accepted screening practice.

Does insurance cover a colonoscopy after a positive FIT in New York?

Usually, yes. New York’s Department of Financial Services says most non-grandfathered policies must cover a follow-up colonoscopy with no cost-sharing after a positive at-home stool test, including anesthesia and polyp removal. Self-funded employer plans and grandfathered plans aren’t bound by these rules, so confirm your plan type with your insurer.

Can I sue if my positive FIT test was ignored in New York?

Possibly. You would need to show that a provider failed to act on the result, such as never referring you for colonoscopy or never telling you, and that the delay worsened your outcome. Under CPLR 214-a, a failure-to-diagnose cancer claim generally must be filed within two and a half years of discovery, with a seven-year outer limit.
