Colorectal Cancer DNA Screening in Stool (Multiplex Tumor DNA Analysis)

This test measures specific substances in your body to help your healthcare provider learn more about your overall health. It can show how well certain organs are working and whether there are signs of infection, inflammation, or other conditions that may need further evaluation or treatment.

The test analyzes DNA fragments from cells in your stool, including those that may indicate colorectal cancer or precancerous polyps. It looks for genetic markers (mutations or abnormalities) that are more common in cancerous or precancerous cells.

This test is performed by collecting a small sample from your body, most often a blood or urine sample, at a laboratory, clinic, or hospital. A trained staff member will guide you through the process, and the sample is then sent to a lab where specialists analyze it and report the results to your provider.

You’ll collect a sample of stool using a provided kit, which is then sent to a lab for analysis. The test is typically done as part of a screening process, often over a 24-hour period or as a single sample collection.

Your healthcare provider may order this test as part of a routine checkup, to help diagnose the cause of symptoms you are experiencing, to monitor a condition you already have, or to see how well a treatment is working over time. It provides valuable information that helps guide decisions about your care.

Your healthcare provider may recommend this test if you’re at higher risk for colorectal cancer (e.g., family history, personal history, or certain genetic conditions) or as part of routine screening if you’re due for a colonoscopy or have symptoms like changes in bowel habits.

Possible results include a normal finding, which usually means the measured values fall within the expected range, or an abnormal finding, which may suggest an infection, a chronic condition, or another issue that needs attention. Your provider will explain what your specific numbers mean and whether any follow-up testing is needed.

Results can be positive (indicating potential cancer or precancerous changes), negative (no detectable abnormalities), or inconclusive (requiring further testing). Follow-up may include additional tests like a colonoscopy to confirm findings.
