CA 125 stands for Cancer Antigen 125. It is a glycoprotein that is typically produced by cells lining the ovaries, fallopian tubes, and the peritoneum.
The CA 125 blood test is a valuable diagnostic tool primarily used to monitor certain types of cancers, particularly ovarian cancer. It measures the level of CA 125, a protein that can be found in higher amounts in the blood of individuals with specific medical conditions, including cancers. Understanding the normal levels and ranges of CA 125 is essential for interpreting the results of this test effectively.
1] Monitoring Ovarian Cancer: For women diagnosed with ovarian cancer, the CA 125 test is a vital tool for monitoring treatment response and detecting recurrence. An increase in CA 125 levels can indicate that cancer is returning or progressing.
1] Diagnosis: While the CA 125 test is not definitive for diagnosing ovarian cancer, it can aid in the diagnostic process, especially when used alongside imaging studies and other tests.
2] Risk Assessment: In women with a family history of ovarian or breast cancer, elevated CA 125 levels can prompt further investigation. However, it is important to note that a high CA 125 level alone does not confirm cancer.
1] False Positives: Many non-cancerous conditions can lead to elevated CA 125 levels. This means that a high result does not automatically indicate cancer.
2] False Negatives: Some women with ovarian cancer may have normal CA 125 blood levels, particularly in the early stages of the disease.
3] Not a Screening Tool: The CA 125 test is not recommended as a routine screening tool for ovarian cancer in the general population due to its limitations and the potential for unnecessary anxiety and invasive procedures.
The CA 125 test normal range typically refers to the values obtained during the CA 125 blood test. For most laboratories, this range is established as follows:
A] Normal: Less than 35 U/mL
B] Borderline: 35 - 65 U/mL
C] Elevated: Greater than 65 U/mL
These ranges serve as guidelines, and it is essential for healthcare providers to interpret them in the context of each patient's unique clinical situation.
The CA 125 blood test levels can fluctuate based on several factors. These can include:
A] Menstrual Cycle: Women may experience elevated CA 125 levels during their menstrual cycle.
B] Pregnancy: CA 125 levels can also increase during pregnancy.
C] Medical Conditions: Conditions such as endometriosis, fibroids, and pelvic inflammatory disease can lead to elevated levels of CA 125, even in the absence of cancer.

The CA 125 blood test level is not recommended as a routine screening tool for ovarian cancer in the general population due to the potential for false positives and negatives.
Yes, CA 125 blood levels can be elevated during pregnancy, which is why it’s essential to consider the context of the test results.
Generally, there are no specific dietary restrictions before the CA 125 test, but it's best to follow your healthcare provider’s instructions.
While lifestyle changes alone may not significantly impact CA 125 levels, maintaining a healthy lifestyle can contribute to overall well-being and potentially reduce the risk of certain conditions.
