Beckman Coulter 33206 Access CEA Diluent for Tumor Markers Assay: INTENDED USE

The Access CEA Diluent (BSA matrix) is intended for use with the Access CEA assay to dilute patient samples containing CEA concentrations greater than the Access CEA Calibrator S5.

Beckman Coulter 33206 Access CEA Diluent for Tumor Markers Assay: SUMMARY AND EXPLANATION

The CEA level in patient samples may exceed the levels of the Access CEA Calibrator S5. If a quantitative value is required, it will be necessary to use the Beckman Coulter 33206 Access CEA Diluent and dilute the sample in order to determine the CEA concentration.

A tumor marker is a substance found in your blood, urine, or body tissue. The term “tumor markers” may refer to proteins that are made by both healthy cells and cancer cells in the body. It may also refer to mutations, changes, or patterns in a tumor’s DNA. Tumor markers are also called biomarkers.

Doctors may use tumor marker tests to learn if you have cancer. These tests can also help doctors to learn more about your cancer and help to plan treatment.

How are tumor marker tests used?

• High tumor marker levels can be a sign of cancer. Along with other tests, tumor marker tests can help doctors diagnose specific types of cancer and plan treatment. Tumor marker tests are most commonly used to do the following:
• Learn if a person has cancer. Higher tumor marker levels may indicate a certain type of cancer. A tumor marker test may be used as a part of your initial diagnosis.
• Guide treatment decisions. Some tumor marker tests tell doctors if they should give chemotherapy or immunotherapy. Others help doctors choose which drugs may work best.
• Check the progress of treatment. Changes in your tumor marker levels can show how well the treatment is working.
• Predict the chance of recovery. Tumor markers can help doctors predict the cancer’s behavior and response to treatment. They can also predict your chance of recovery.
• Predict or watch for recurrence. Recurrence is when cancer comes back after treatment. Tumor marker tests can help predict how likely this is. That’s why these tests might be part of your care after treatment ends. They may help find a recurrence sooner than other tests.
• Tumor marker tests may also be used to look for cancer in people with a high risk of the disease. Or you might have these tests to learn more about the cancer when doctors first find it.

Limits of tumor marker tests

Tumor marker tests are not perfect. They are often not specific for cancer and may not be sensitive enough to pick up a cancer recurrence. The presence of tumor markers alone is not enough to diagnose cancer. You will probably need other tests to learn more about a possible cancer or recurrence. Some limits to tumor marker tests are listed below.

• A condition or disease that is not cancer can raise tumor marker levels.
• People without cancer can have high tumor marker levels.
• Tumor marker levels can change over time. The tests may not get the same result every time.
• Tumor marker levels may not go up until cancer gets worse. This does not help find cancer early, or in people at high risk. It also does not help find a recurrence.
• Some cancers do not make tumor markers that are found in the blood. And, some types of cancer have no known tumor markers.
• Your tumor marker levels might not go up, even if your type of cancer usually makes tumor markers.
