PT INR Test Price in Pakistan: PKR 770 at Marham Lab

Prothrombin is a protein made by the liver and one of several clotting factors. MedlinePlus explains that when you are injured, your clotting factors work together to form a blood clot, and that a prothrombin time test measures how many seconds it takes for a clot to form in a blood sample. At Marham Lab a PT with INR test costs PKR 770.

Why the Report Shows a Ratio

MedlinePlus explains that because results vary between laboratories and methods, the PT is converted into an INR, an international normalised ratio. Using the ratio makes it easier for providers to compare results from different labs.

This matters if you are on warfarin and have ever switched laboratory. The INR is designed to be comparable across labs, while the raw PT seconds are not. Quote the INR to your doctor, not the seconds.

If You Take Warfarin, Ask About Your Dose Timing

MedlinePlus gives one preparation instruction specific to this test: if you are taking warfarin, you may need to delay your daily dose until after testing.

Ask the doctor who ordered the test, and do not simply skip a dose on your own. Book the sample early in the day so any delayed dose can still be taken on time.

What It Is Used For

MedlinePlus lists the main uses.

• Seeing how well warfarin, a blood thinning medicine sold under brand names including Coumadin, is preventing clots, with the dose adjusted on the result
• Finding the reason for abnormal blood clots
• Finding the reason for unusual bleeding
• Checking clotting ability before a procedure or surgery that may cause bleeding
• Checking for liver problems
• Checking for vitamin K deficiency

MedlinePlus notes it is often done alongside a partial thromboplastin time test, which checks different coagulation factors.

Symptoms That Prompt Testing

Bleeding disorder: unexplained heavy bleeding, bruising easily, unusually heavy nose bleeds, and unusually heavy menstrual periods.

Clotting disorder: leg pain or tenderness, leg swelling, redness or darkening of the skin on the leg, skin that feels warm, trouble breathing, cough, chest pain, and rapid heartbeat and breathing.

That second list deserves emphasis. Leg swelling with pain, or breathlessness with chest pain, can indicate a clot in the leg or lungs. Those are reasons to see a doctor urgently rather than to book a test and wait for the report.

Reading Your Result

For people on warfarin, MedlinePlus frames it as risk: an INR too low may mean risk of dangerous clots, and too high may mean risk of dangerous bleeding. If the INR is not in range, the provider will probably change the warfarin dose.

Food and Drink Change This Result

Unusually for a blood test, diet moves the number. MedlinePlus lists things that may affect PT/INR results:

• Alcohol
• Foods high in vitamin K, such as green leafy vegetables
• Soybean and canola oils
• High fat diets

It advises asking your provider what you should avoid before the test. The practical advice for anyone on warfarin is consistency rather than avoidance: a sudden large plate of saag or spinach before a test can shift an INR that was otherwise stable.

Tell your provider about all medicines and supplements too, since MedlinePlus notes some affect results.

What Happens During the Test

MedlinePlus notes the test may be done on blood from a vein or from a fingertip. For the vein sample, a trained phlebotomist takes a small sample from your arm using a small needle, usually in under five minutes. In Lahore the sample can be collected at your home, which is useful for anyone testing regularly on warfarin.

MedlinePlus also describes at-home INR kits, used by some people who have taken warfarin for a long time, and notes that results from a home kit still need reviewing with your provider.

Tests Often Ordered Alongside

MedlinePlus notes certain [liver tests](/labs/tests/lft-test-price) are sometimes ordered with a PT/INR, naming AST and ALT. That is because prothrombin is made in the liver, so a prolonged PT can reflect liver function rather than a clotting disorder.

پی ٹی آئی این آر ٹیسٹ یہ ناپتا ہے کہ خون کو جمنے میں کتنا وقت لگتا ہے۔ پروتھرومبن ایک پروٹین ہے جو جگر بناتا ہے اور خون جمانے میں مدد دیتا ہے۔

یہ ٹیسٹ زیادہ تر ان لوگوں کا ہوتا ہے جو خون پتلا کرنے والی دوا وارفرین لیتے ہیں، تاکہ دوا کی مقدار درست رکھی جا سکے۔ اس کے علاوہ آپریشن سے پہلے، غیر معمولی خون بہنے پر، یا جگر کی جانچ کے لیے بھی کروایا جاتا ہے۔

ایک اہم بات۔ اگر آپ وارفرین لیتے ہیں تو ڈاکٹر سے پوچھیں کہ ٹیسٹ سے پہلے اس دن کی خوراک لینی ہے یا ٹیسٹ کے بعد۔ اپنی مرضی سے دوا نہ چھوڑیں۔

دوسری بات جو اکثر لوگ نہیں جانتے۔ کھانے پینے کی چیزیں اس رپورٹ پر اثر ڈالتی ہیں۔ سبز پتوں والی سبزیاں، شراب، سویابین اور کینولا آئل، اور زیادہ چکنائی والی خوراک رپورٹ بدل سکتی ہیں۔ وارفرین لینے والوں کے لیے بہتر یہ ہے کہ خوراک میں اچانک بڑی تبدیلی نہ کریں۔

اگر ٹانگ میں سوجن اور درد ہو، سانس پھولے یا سینے میں درد ہو تو فوراً ڈاکٹر کے پاس جائیں، ٹیسٹ کا انتظار نہ کریں۔ مرہم لیب میں اس ٹیسٹ کی قیمت سات سو ستر روپے ہے۔

Final Thoughts

For anyone on warfarin this is a routine test where consistency matters more than perfection: same approximate diet, same timing habit, and the INR quoted rather than the seconds. For everyone else it is a check on whether blood clots normally, commonly before surgery. And leg swelling or breathlessness with chest pain is a reason to go to a doctor now rather than to book a test.
