What is a normal cancer antigen number?

What is a good cancer antigen number?

The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer. Your doctor may recommend other tests and procedures to determine your diagnosis.

What does an elevated ca15 3 mean?

In metastatic breast cancer, the highest levels of CA 15-3 often are seen when the cancer has spread to the bones and/or the liver. Increasing concentrations of CA 15-3 over time may indicate that a person is not responding to treatment or that the cancer is recurring.

What is a normal CA 27/29 level?

Healthcare providers measure CA 27-29 in units per milliliter (U/mL). A normal test should be less than or equal to 38 U/mL. Here is what your test results may mean: If your CA 27-29 is less than 38 U/mL, it may mean that you don’t have active breast cancer.

What is considered a high CEA level?

Levels of CEA higher than 20 ng/mL are considered very high. If you have CEA levels this high and you also have symptoms of cancer, it strongly suggests the cancer has not been removed successfully after treatment. It may also suggest that the cancer has metastasized, or spread, to other parts of your body.

What is a bad CA 125 level?

In the patient who is being evaluated for a pelvic mass, a CA 125 level greater than 65 is associated with malignancy in approximately 90% of cases. However, without an obvious pelvic mass, this association is much weaker.

What is a normal CA 15-3 level?

Cancer antigen 15-3 (CA 15-3) is used to monitor response to breast cancer treatment and disease recurrence. The reference range of serum CA 15-3 is less than 30 U/mL. The upper limit of the range varies depending on the laboratory and kit used for the test.

How accurate is tumor marker CA 15-3?

CA 15-3 in the diagnostic and follow up of patients with breast cancer has a sensitivity ranging from 75-76.9% and the specificity ranging from 85.5-93%.

What is a high tumor marker number?

Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.

What is the difference between CA 27/29 and CA 15 3?

Since all breast cancers do not express the CA 27-29 antigen, this assay cannot detect all breast cancers. The CA 15-3 assay can be used instead of the CA 27-29 assay. Although CA 27-29 may be more sensitive for breast cancer, its indications and limitations parallel those of CA 15-3.

What is a normal CEA level?

The normal range is 0 to 2.5 ng/mL (0 to 2.5 µg/L). In smokers, slightly higher values may be considered normal (0 to 5 ng/mL, or 0 to 5 µg/L).
