CA-125 Test Price in Pakistan: Rs 3,360 at Marham Lab

CA-125 measures a protein called cancer antigen 125 in your blood. MedlinePlus explains that it is a type of tumour marker, meaning a substance often made by cancer cells or by normal cells in response to cancer. It adds that organs in the female reproductive system may make CA-125 when they are inflamed, including in response to normal bodily functions such as a menstrual period. At Marham Lab a CA-125 test costs Rs 3,360, reduced from Rs 4,800.

This Is Not an Ovarian Cancer Screening Test

This needs saying before anything else, because it is the commonest reason people book this test for themselves and the commonest reason it causes needless fear.

MedlinePlus states it directly: your provider cannot use a CA-125 to screen for ovarian cancer if you are not at high risk. The reason it gives is that other conditions which are not cancer also cause high CA-125 levels. It lists them.

• Endometriosis
• Pelvic inflammatory disease (PID)
• Uterine fibroids
• Liver disease

MedlinePlus adds that natural bodily functions including your menstrual period and pregnancy can also raise CA-125.

Uterine fibroids and endometriosis are common. A woman with either, or one who happens to be menstruating, can have a raised CA-125 and no cancer at all. That is precisely why the test is not used as a general check, and why booking it without a doctor's instruction tends to produce anxiety rather than information.

What It Is Actually For

MedlinePlus lists three legitimate uses, and notes which is the main one.

So this is largely a monitoring test for women already diagnosed, and a supporting test where something has already been found. MedlinePlus is clear on the limit of what it can do: only a biopsy can diagnose ovarian cancer.

Who Counts as High Risk

MedlinePlus lists the factors that make ovarian cancer more likely, which is the group in whom testing may be suggested.

• Having a mother or sister, or two or more other relatives, who have had ovarian cancer
• Having family members who have had breast cancer or colorectal cancer
• Having inherited certain gene changes, including changes in the BRCA1 or BRCA2 genes, or Lynch syndrome, an inherited disorder that raises the risk of many cancers
• Having had breast, uterine or colorectal cancer yourself

MedlinePlus closes that section with sensible advice: if you are concerned about getting ovarian cancer, talk with your provider about your risk. That conversation, rather than a test booked alone, is the right first step.

Reading the Result Cuts Both Ways

This is the part worth reading slowly, because the test is unreliable in both directions.

MedlinePlus states that while high CA-125 levels do not always mean ovarian cancer, a normal CA-125 result does not rule it out. It gives two reasons: levels may be low in the early stages of cancer, and not everyone with ovarian cancer makes high levels of CA-125.

So a reassuring number is not a clearance, and an alarming number is not a diagnosis. Both need a doctor.

For women already under treatment, MedlinePlus explains how the trend is read.

Notice that each of these depends on several measurements over time rather than one. A single CA-125 in isolation tells an oncologist very little.

A Second Marker Is Sometimes Used

MedlinePlus notes that the most common type of ovarian cancer is epithelial ovarian cancer, and that if you have been treated for this type you may be tested for a tumour marker called HE4 alongside CA-125. It adds that some studies show measuring both provides more accurate information for checking whether treatment is working and for detecting a return of this cancer.

HE4 is not currently listed on Marham. If your oncologist has asked for it, ask them where it is available locally.

If You Have Symptoms, See a Doctor Rather Than Booking a Marker

Persistent bloating, a swollen abdomen, pelvic or abdominal pain, feeling full quickly, or a change in how often you need to pass urine are symptoms that deserve a gynaecologist's assessment. The right investigation usually begins with an examination and an ultrasound rather than a blood marker, and MedlinePlus notes CA-125 is used alongside imaging when a lump has already been found.

Take symptoms to a doctor. Let the doctor decide whether this test belongs in the plan.

How to Prepare

MedlinePlus states you do not need any special preparations for a CA-125 blood test. No fasting is required.

Two things are worth mentioning to the doctor who ordered it. Where you are in your menstrual cycle, since MedlinePlus names menstruation as a cause of raised CA-125, and any diagnosis of endometriosis, fibroids, pelvic inflammatory disease or liver disease. All four change how the number should be read.

What Happens During the Test

A trained phlebotomist takes a small blood sample from a vein in your arm using a small needle. MedlinePlus notes it usually takes less than five minutes and that you may feel a little sting as the needle goes in or out. There is very little risk beyond slight pain or bruising, which settles quickly. In Lahore the sample can be collected at your home at no extra cost.

MedlinePlus advises reviewing your results with your provider, who will consider them alongside other information about your condition to discuss your diagnosis, treatment and need for further testing.

سی اے ون ٹوئنٹی فائیو خون میں ایک پروٹین کی مقدار معلوم کرتا ہے جسے ٹیومر مارکر کہا جاتا ہے۔ یہ کینسر کے خلیوں سے یا کینسر کے جواب میں عام خلیوں سے بھی بن سکتا ہے۔

سب سے ضروری بات پہلے۔ یہ ٹیسٹ عام خواتین میں بیضہ دانی کے کینسر کی اسکریننگ کے لیے استعمال نہیں ہوتا۔ عالمی طبی معلومات کے مطابق ڈاکٹر اسے اسکریننگ کے لیے صرف ان خواتین میں استعمال کرتے ہیں جن کا خطرہ بہت زیادہ ہو۔ وجہ یہ ہے کہ کئی ایسی حالتیں بھی اس کی مقدار بڑھا دیتی ہیں جو کینسر نہیں ہوتیں، جیسے اینڈومیٹریوسس، پیٹ کے نچلے حصے کا انفیکشن، بچہ دانی کی رسولیاں، اور جگر کی بیماری۔ اس کے علاوہ ماہواری اور حمل بھی اسے بڑھا دیتے ہیں۔

یعنی اگر کسی خاتون کو فائبرائڈ ہوں یا ماہواری کے دن ہوں تو رپورٹ زیادہ آ سکتی ہے حالانکہ کینسر نہیں ہوتا۔ اسی لیے ڈاکٹر کے کہے بغیر یہ ٹیسٹ کروانا پریشانی کا سبب بنتا ہے، معلومات کا نہیں۔

اس ٹیسٹ کا اصل استعمال کیا ہے۔ سب سے عام استعمال یہ دیکھنا ہے کہ بیضہ دانی کے کینسر کا علاج کام کر رہا ہے یا نہیں، اور علاج کے بعد کینسر واپس آیا ہے یا نہیں۔ اس کے علاوہ اگر الٹراساؤنڈ میں کوئی گلٹی نظر آئے تو ڈاکٹر دیگر ٹیسٹوں کے ساتھ یہ بھی کرواتے ہیں۔ یاد رکھیں، بیضہ دانی کے کینسر کی تشخیص صرف بایوپسی سے ہوتی ہے۔

دونوں طرف کی بات سمجھ لیں۔ رپورٹ زیادہ آنے کا مطلب کینسر نہیں، اور رپورٹ نارمل آنے کا مطلب یہ بھی نہیں کہ کینسر نہیں ہے، کیونکہ ابتدائی مرحلے میں یہ مقدار کم ہو سکتی ہے اور کچھ مریضوں میں یہ بڑھتی ہی نہیں۔

اگر پیٹ میں مسلسل پھولن، سوجن، درد، جلدی پیٹ بھر جانا، یا پیشاب کی عادت میں تبدیلی ہو تو ماہر امراض نسواں سے رجوع کریں۔ تشخیص عام طور پر معائنے اور الٹراساؤنڈ سے شروع ہوتی ہے۔ ٹیسٹ سے پہلے کوئی خاص تیاری نہیں چاہیے۔ ڈاکٹر کو ماہواری کے دن اور فائبرائڈ یا اینڈومیٹریوسس کے بارے میں ضرور بتائیں۔ مرہم لیب میں اس ٹیسٹ کی قیمت تینتیس سو ساٹھ روپے ہے اور لاہور میں گھر سے نمونہ لینے کی سہولت مفت ہے۔

Final Thoughts

CA-125 is a valuable test in the right hands and a misleading one in the wrong context. For a woman being treated for ovarian cancer it tracks whether the treatment is working, and the trend across several results is what matters. For a woman with no diagnosis and no unusual family history it is not a screening test, because fibroids, endometriosis, pelvic infection, liver disease, pregnancy and even a period can all lift it. If you have symptoms, start with a gynaecologist and an ultrasound, and let the doctor decide whether this marker belongs in the plan.
