What's this test for?

This test is ideal if you're experiencing persistent digestive problems, unexplained abdominal pain, changes in bowel habits, blood in stool, or unexplained weight loss. It helps detect early signs of colorectal and colon cancer by measuring specific tumor markers in your blood, along with comprehensive metabolic and blood cell counts. Many people use this test when they have concerning symptoms, a family history of colorectal cancer, or want proactive screening for peace of mind.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your tumor markers and other blood values mean for your digestive health and cancer risk. These notes include personalized recommendations such as dietary changes, when to follow up with a gastroenterologist, or whether further diagnostic testing like a colonoscopy may be needed. You'll also get the standard lab report and can track your biomarker levels over time using our trends feature to monitor any changes.

What's included in this test?

This panel measures CEA, CA 19-9, Complete Blood Count (CBC with Differential and Platelets including White Blood Cell Count, Red Blood Cell Count, Hemoglobin, Hematocrit, Platelets, and comprehensive white cell differential), and Comprehensive Metabolic Profile (including eGFR, Glucose, Electrolytes, Kidney function markers BUN and Creatinine, and Liver function markers ALT, AST, Alkaline Phosphatase, Bilirubin, and Proteins). This comprehensive panel measures CEA and CA 19-9, which are tumor markers that can be elevated in colorectal cancer. It also includes a Complete Blood Count to check for anemia that can result from internal bleeding, and a Comprehensive Metabolic Profile to assess liver and kidney function, which can be affected by cancer or digestive issues. Together, these measurements provide important screening data to identify potential concerns early and guide next steps for diagnosis or monitoring.

How should I prepare for this test?

You should fast for 12 hours before your blood collection, which means no food or beverages except water during that time. This fasting requirement ensures accurate glucose and metabolic measurements. Results typically take about 3 business days, though this may be extended if confirmation testing is needed.

When will I get my results?

You can expect your results within approximately 3 business days after your blood is collected. In some cases, if confirmation or additional testing is required, the turnaround time may be slightly extended. You'll be notified as soon as your results are ready to view in your secure online account.

Who should consider getting this test?

This test is valuable for anyone over 45, especially those with a family history of colorectal cancer, inflammatory bowel disease, or polyps. It's also important if you're experiencing warning signs like persistent abdominal discomfort, rectal bleeding, unexplained weight loss, or changes in bowel movements. People with risk factors such as obesity, smoking, heavy alcohol use, or a diet high in red meat should also consider regular screening.

What symptoms indicate I may need this test?

Common warning signs include persistent changes in bowel habits like diarrhea or constipation, blood in your stool or rectal bleeding, ongoing abdominal cramps or pain, and unexplained weight loss. Other symptoms that warrant testing include persistent fatigue, feeling like your bowel doesn't empty completely, and narrow or ribbon-like stools. If you experience any of these symptoms, especially if they last more than a few weeks, this screening can help identify potential issues.

What do elevated tumor markers like CEA mean?

Elevated CEA or CA 19-9 levels can indicate the presence of colorectal cancer, but they can also be elevated due to non-cancerous conditions like inflammatory bowel disease, liver disease, or even smoking. These markers are not definitive for cancer diagnosis on their own, which is why your doctor will consider them alongside your symptoms, medical history, and may recommend follow-up tests like colonoscopy or imaging. They're most useful for monitoring known cancer or detecting early warning signs.

How can I reduce my risk of colorectal cancer?

Maintaining a healthy lifestyle significantly reduces colorectal cancer risk. Focus on a diet rich in fruits, vegetables, and whole grains while limiting red and processed meats. Stay physically active with at least 30 minutes of exercise most days, maintain a healthy weight, and limit alcohol consumption. Avoid smoking, and if you're over 45 or have risk factors, follow recommended screening guidelines. Regular screening is one of the most effective ways to prevent colorectal cancer by catching polyps before they become cancerous.

What happens if my results are abnormal?

If your tumor markers are elevated or other values are outside normal ranges, your doctor will typically recommend follow-up testing to investigate further. This may include a colonoscopy, which is the gold standard for diagnosing colorectal cancer and can remove polyps during the procedure. Additional imaging tests like CT scans may also be ordered. Remember that abnormal results don't automatically mean cancer—many conditions can affect these markers, and early detection greatly improves treatment outcomes.

How often should I get screened for colorectal cancer?

For average-risk adults, colorectal cancer screening should begin at age 45 and continue regularly. If using blood-based tumor marker tests, annual testing may be appropriate, though colonoscopy every 10 years remains the gold standard. If you have a family history of colorectal cancer or other risk factors, your doctor may recommend more frequent screening starting at an earlier age. Those with concerning symptoms should be tested immediately regardless of age or last screening date.
