Blood Smear Test Price in Pakistan: Rs 920 at Chughtai Lab

A blood smear checks a sample of your blood under a microscope to see whether your blood cells look normal. MedlinePlus explains that a sample of blood is spread on a glass slide, the slide is treated with a special stain that makes the cells easier to see, and a laboratory professional then looks at it under a microscope to check the size, shape and number of cells. At Chughtai Lab, blood complete examination with peripheral film costs Rs 920, reduced from Rs 1,150.

A Machine Counts Your Cells. A Person Looks at Them.

This is the difference between a smear and an ordinary blood count, and it is the reason your doctor asked for it.

A [CBC](/labs/tests/cbc-test-price) is run on an analyser that counts cells and measures their average size. A blood smear adds a human being with a microscope looking at what those cells actually look like. MedlinePlus notes the smear checks size, shape and number, and that it also gives your provider more information about what your blood cells look like, including their colour.

MedlinePlus lists what is examined.

MedlinePlus lists peripheral smear, peripheral blood film, blood film, manual differential, differential slide and blood cell morphology among the other names for it. If your prescription says any of those, this is the test.

A Smear Alone Cannot Diagnose Anything

Worth reading before the report worries you.

MedlinePlus states plainly that a blood smear alone cannot diagnose a disease, and that results usually cannot diagnose a medical condition on their own. Your provider combines the smear with your medical history, symptoms and other test results to reach a diagnosis.

The report describes what your blood cells look like and how many there are, and notes anything else unusual, for example whether any parasites were found. MedlinePlus adds that if the results are not normal, your provider may order more tests to find the cause.

Why It Gets Ordered

MedlinePlus gives four situations.

After an abnormal CBC. A smear can confirm abnormal CBC results by checking the size and number of your cells. This is the commonest route to the test in Pakistan, where a low haemoglobin on a routine CBC is very frequent.

When you have symptoms affecting blood cells. MedlinePlus lists fatigue, jaundice which turns the skin and eyes yellow, nosebleeds or other unusual bleeding, easy bruising, fever, bone pain, and swollen lymph nodes.

To monitor treatment. If you are being treated for a condition affecting your blood cells, such as anaemia or a blood cancer, MedlinePlus notes a smear can help show whether the treatment is working.

To look for parasites. MedlinePlus names malaria, spread by bites from infected mosquitoes, and babesiosis, spread mainly by infected ticks. It notes symptoms can resemble flu, including fever, chills, body aches, nausea and fatigue.

That last one matters here. A smear is how [malaria](/labs/tests/malaria-test-price) parasites are actually seen, which is why a doctor investigating an unexplained fever in Pakistan may ask for a film rather than only a rapid test.

What Abnormal Results Can Point To

MedlinePlus groups the findings by cell type.

MedlinePlus also notes that severe illness, stress and blood transfusions can cause abnormal smear results.

Thalassaemia deserves a mention because carrier rates are high in Pakistan. A smear showing small pale red cells is one of the findings that leads a doctor to order [haemoglobin electrophoresis](/labs/tests/hb-electrophoresis-test-price), which is the test that actually identifies carriers.

How to Prepare

MedlinePlus states you do not need any special preparation for a blood smear.

One thing to check. MedlinePlus notes that if your provider has ordered other blood tests at the same time, you may need to fast for several hours. Read the whole prescription rather than the smear line alone, since a lipid profile or fasting sugar booked alongside changes the instruction.

Bring your previous CBC report if you have one. The smear is usually read against it, and the laboratory doctor benefits from seeing what prompted the request.

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. It adds that sometimes the sample is taken by pricking a finger, and that when testing a baby the heel is pricked instead.

MedlinePlus states there is very little risk to a blood test beyond slight pain or bruising, which settles quickly. In Lahore the sample can be collected at your home at no extra cost.

بلڈ سمیئر یا پیریفرل فلم ایک ایسا ٹیسٹ ہے جس میں خون کے نمونے کو شیشے کی سلائیڈ پر پھیلا کر، خاص رنگ لگا کر، خوردبین کے نیچے دیکھا جاتا ہے۔ اس میں خون کے خلیوں کی جسامت، شکل اور تعداد دیکھی جاتی ہے۔

عام بلڈ ٹیسٹ اور اس میں فرق کیا ہے۔ عام سی بی سی مشین خلیوں کو گنتی ہے، جبکہ سمیئر میں ایک ماہر خود خوردبین سے دیکھتا ہے کہ خلیے کیسے نظر آتے ہیں۔ اسی لیے ڈاکٹر اکثر سی بی سی رپورٹ غیر معمولی آنے کے بعد یہ ٹیسٹ تجویز کرتے ہیں۔

اس ٹیسٹ میں تین طرح کے خلیے دیکھے جاتے ہیں۔ سرخ خلیے جو آکسیجن پہنچاتے ہیں، سفید خلیے جو انفیکشن سے لڑتے ہیں، اور پلیٹ لیٹس جو خون جمانے میں مدد دیتے ہیں۔

ایک ضروری بات۔ اکیلا سمیئر کسی بیماری کی تشخیص نہیں کر سکتا۔ ڈاکٹر اسے آپ کی علامات، طبی تاریخ اور دیگر ٹیسٹوں کے ساتھ ملا کر پڑھتے ہیں۔ رپورٹ غیر معمولی آئے تو مزید ٹیسٹ ہو سکتے ہیں۔

یہ ٹیسٹ ملیریا کے جراثیم دیکھنے کے لیے بھی استعمال ہوتا ہے، اس لیے بخار کی وجہ معلوم نہ ہو تو ڈاکٹر یہ ٹیسٹ کرواتے ہیں۔ پاکستان میں تھیلیسیمیا بھی عام ہے۔ اگر سمیئر میں سرخ خلیے چھوٹے اور پھیکے نظر آئیں تو ڈاکٹر ہیموگلوبن الیکٹروفوریسس کا ٹیسٹ تجویز کر سکتے ہیں۔

ٹیسٹ سے پہلے کوئی خاص تیاری نہیں چاہیے۔ البتہ اگر اسی نمونے سے کوئی اور ٹیسٹ بھی ہو رہا ہو تو بھوکا رہنا پڑ سکتا ہے، پورا نسخہ دیکھ لیں۔ پرانی سی بی سی رپورٹ ساتھ لے جائیں۔ لاہور میں گھر سے نمونہ لینے کی سہولت موجود ہے۔

Final Thoughts

A blood smear is the step where someone actually looks at your blood rather than reading a machine's summary of it. That is worth doing when a CBC came back odd, when a fever has no explanation, or when treatment for anaemia or a blood disorder needs checking. It is also a test whose report rarely means anything on its own, so bring it back to the doctor who ordered it along with the CBC that prompted it.
