CA 125 Test in Chennai
Told you have an ovarian cyst, or dealing with bloating and pelvic pain that keeps coming back? The CA 125 test in Chennai measures a protein that can rise with ovarian conditions. On its own it proves nothing, which is exactly why it should be read next to your scan and your symptoms, and that is how our gynaecology team uses it.

What is a CA 125 Test?
CA 125 is a protein that can be measured through a blood test and is mainly used to monitor women diagnosed with ovarian cancer. A CA 125 test in Chennai can help assess how well treatment is working and check for signs of the disease returning. At Unittas Hospital, the test is performed with care and clear guidance, helping patients receive reliable information at an important stage of their care.
CA 125 is a protein that can be produced in higher amounts by certain cells, including some ovarian cancer cells. The blood test measures how much of this protein is present in the bloodstream.
It is not used as a routine screening test for healthy women without symptoms or risk factors. Instead, it is most helpful when a woman already has a known ovarian, fallopian tube or peritoneal cancer, or when there are symptoms or findings that need further investigation.
Why Might You Need a CA 125 Test?
You may be asked to take a CA 125 test if you:
- Have been diagnosed with ovarian cancer and need monitoring during or after treatment
- Need to check whether cancer treatment is working
- Are being followed up after treatment to look for possible recurrence
- Have symptoms or an ultrasound finding that raises concern about a pelvic mass
- Belong to a higher-risk group and further assessment is advised
The result is always interpreted together with your symptoms, examination findings and other investigations such as ultrasound.
How is the CA 125 Test Done?
The CA 125 test for female is a simple blood sample:
- A small amount of blood is taken from a vein in your arm.
- The sample is sent to the laboratory.
- The level of CA 125 is measured and reported in units per millilitre (U/mL).
Results are usually available within one working day.
Preparation for the CA 125 Test
No special preparation or fasting is normally required. You can eat and drink as usual. Tell your doctor if you are currently having your period, as this can sometimes raise the level slightly. Inform the team about any medicines or recent procedures. Follow any specific instructions given for your appointment.
Understanding Your CA 125 Results
Most laboratories consider a level below 35 U/mL as within the CA 125 normal range, though exact cut-offs can vary slightly.
A raised CA 125 level can occur with:
| CA 125 Level | General Meaning |
|---|---|
| Within normal range (usually <35 U/mL) | Does not rule out disease, but is often reassuring in context |
| Raised | May be linked to ovarian cancer or several non-cancer conditions |
Reference ranges vary between laboratories. Always read your report against the range printed on it, and with your doctor.
- Ovarian, fallopian tube or peritoneal cancer
- Endometriosis
- Uterine fibroids
- Pelvic inflammatory disease
- Pregnancy or menstruation
- Liver disease or other non-gynaecological conditions
In women already diagnosed with ovarian cancer, a falling level often suggests treatment is helping, while a rising level may indicate the disease is progressing or returning. Your doctor will explain what the number means for you and whether further tests are needed.

Not necessarily. Many non-cancer conditions can also raise the level. Further tests are needed to understand the cause.
It is not accurate enough for routine screening in healthy women. It is more useful for monitoring known diseases or investigating specific concerns.
Falling levels often indicate that treatment is working. Rising levels may suggest the disease is not responding or has returned.
Yes. Levels can be slightly higher during menstruation. Tell your doctor if you are having your period when the sample is taken.

The test is mainly used in women. It is rarely requested in men and is not routinely useful for them.
Your doctor may arrange an ultrasound, other blood tests or specialist review and will discuss the findings with you.
No. Some ovarian cancers, especially early-stage ones, do not raise CA 125 levels. Clinical assessment and imaging remain important.
Yes. Endometriosis and other benign conditions commonly cause elevated levels.
The schedule depends on your individual situation and treatment plan. Your doctor will advise the appropriate interval.
Sometimes it is combined with other tests or imaging to give a clearer picture, especially when assessing a pelvic mass.
