Why is the CA 27.29 test ordered?
The CA 27.29 test is typically ordered to monitor individuals with a history of breast cancer for recurrence. The test can provide information about how well a treatment is working and if the cancer has returned after treatment.
What does the CA 27.29 test measure?
The CA 27.29 test measures the level of the protein CA 27.29 in the blood. CA 27.29 is a type of tumor marker, which is a substance that is produced by cancer cells or by the body in response to cancer.
Interpreting CA 27.29 Test Results
What do high levels of CA 27.29 in a test indicate?
High levels of CA 27.29 in a test can indicate that breast cancer is present or has returned after treatment. However, high levels can also occur in other types of cancers or in certain benign conditions, so the test is not specific to breast cancer.
What do normal levels of CA 27.29 in a test indicate?
Normal levels of CA 27.29 in a test can suggest that no cancer is present or that cancer treatment has been successful. However, not all individuals with breast cancer will have elevated levels of CA 27.29, so a normal result does not definitively rule out the presence of cancer.
How can the results of the CA 27.29 test vary over time?
The levels of CA 27.29 can vary over time and are often monitored regularly in individuals with a history of breast cancer. An increasing trend in CA 27.29 levels may suggest that the cancer is growing or has returned, while a decreasing trend can indicate that treatment is effective.
