CA125 Blood Test: Procedure, Price, Normal Range & Interpretation
When it comes to women’s health, some tests play a crucial role in spotting early signs of serious health issues. One of them is the CA125 blood test. Often recommended for women experiencing unexplained bloating, pelvic pain, or irregular cycles, this simple test helps doctors take timely action when treatment is easier and more effective.
What is CA125 Blood Test?
The CA125 test measures the level of a protein called cancer antigen 125 (CA125) in your blood. These proteins, also known as tumor markers, may be produced by both cancerous and normal cells. Elevated levels can signal potential health risks such as:
- Ovarian cancer
- Endometriosis
- Pelvic inflammatory disease (PID)
- Uterine fibroids
- Menstruation or pregnancy
Note: The CA125 test alone cannot diagnose cancer. Additional tests like scans or biopsies are required.
Why is the CA125 Test Done?
- Early Identification: Helps detect early signs of ovarian cancer, especially in high-risk individuals.
- Monitor Treatment: Tracks how well the body is responding to ovarian cancer treatment.
- Detect Recurrence: Regular testing post-treatment helps identify if cancer has returned.
- Other Conditions: Elevated levels may also indicate non-cancerous issues like fibroids or infections.
How to Interpret CA125 Blood Test Results
| CA125 Level (U/mL) | Interpretation |
|---|---|
| 0–35 | Normal range |
| 35–100 | May indicate mild conditions like endometriosis or fibroids |
| 100+ | Possible sign of ovarian cancer (requires further testing) |
Who Should Get a CA125 Test?
- Women with symptoms like bloating, appetite changes, or frequent urination
- Patients undergoing ovarian cancer treatment
- Women with a family history of ovarian cancer
- Post-treatment patients to monitor recurrence
How to Prepare for a CA125 Test
- No Fasting Required: You can eat and drink normally before the test.
- Inform your doctor about any medications or supplements.
- Medical Conditions: Disclose any known conditions like fibroids or PID.
- Menstruation: Periods can temporarily raise CA125 levels—let your doctor know.
What Causes Elevated CA125 Levels?
- Pregnancy
- Menstruation
- Endometriosis
- Uterine fibroids
- Liver disease
- Pelvic infections
