Free Thyroid Test Price in Pakistan: Rs 3,500 at Marham Lab

The thyroid is a small butterfly shaped gland in the front of your neck. NIDDK explains that it makes two thyroid hormones, thyroxine (T4) and triiodothyronine (T3), and that these hormones control how the body uses energy, so they affect nearly every organ including your heart. A free thyroid function test measures FT3, FT4 and TSH in one blood sample. At Marham Lab it costs Rs 3,500, reduced from Rs 5,000.

Free T4 or Total T4: The Reason This Panel Exists

This is the whole point of the test, and it is almost never explained at the counter.

NIDDK sets it out clearly. Proteins in your blood bind, or attach, to T4. Bound T4 is kept in reserve in the blood until it is needed. Free T4 is not bound to these proteins and is available to enter body tissues. Because changes in binding protein levels do not affect free T4 levels, NIDDK states that many health care professionals prefer to measure free T4.

That matters because several ordinary situations change your binding proteins without anything being wrong with your thyroid. NIDDK names them.

NIDDK is explicit that in these cases high or low T4 levels may not mean you have thyroid problems.

So a pregnant woman or a woman on the pill can have a total T4 that looks abnormal while her thyroid is working normally. The free T4 sees past that, which is why this panel is the one usually ordered in pregnancy.

Which Thyroid Panel Should You Book

Marham lists several and they are not interchangeable. Book what your doctor wrote.

If your prescription says FT3 and FT4, or TFT-1, this is the panel. If it says T3 and T4 without the word free, the other one is being asked for. The difference is not a quality upgrade, it is a different measurement, and paying more does not automatically make it the right test for you.

What TSH Tells Your Doctor First

NIDDK explains that health care professionals usually check the amount of TSH in your blood first, and that TSH is a hormone made in the pituitary gland which tells the thyroid how much T4 and T3 to make.

NIDDK adds an important line: if the TSH result is not normal, you will need at least one other test to find the cause. That is the reason a panel exists rather than a single number.

Why T3 Is In There

NIDDK gives the specific case. If your health care professional thinks you may have hyperthyroidism even though your T4 level is normal, a T3 test may be used to confirm the diagnosis. Sometimes T4 is normal yet T3 is high, so measuring both can be useful in diagnosing an overactive thyroid.

Without the T3, that pattern is missed entirely.

What These Tests Help Diagnose

NIDDK lists the conditions thyroid tests help diagnose.

• Hyperthyroidism, when thyroid hormone levels are too high
• Graves' disease, the most common cause of hyperthyroidism
• Hypothyroidism, when thyroid hormone levels are too low
• Hashimoto's disease, one of the most common causes of hypothyroidism
• Thyroid nodules and thyroid cancer

NIDDK also notes that measuring thyroid antibodies may help diagnose an autoimmune thyroid disorder such as Graves' disease or Hashimoto's disease, and that thyroid antibodies are made when your immune system attacks the thyroid gland by mistake. It says a professional may order antibody tests if other blood results suggest thyroid disease. Those are separate tests from this panel.

When Blood Tests Are Not the Whole Answer

Worth knowing so you are not surprised by the next referral.

NIDDK explains that blood tests come first and that your doctor may also order imaging. An ultrasound of the thyroid is most often used to look at thyroid nodules, which are lumps in the neck, and can help tell whether a nodule is more likely to be cancerous. A thyroid scan looks at the size, shape and position of the gland. A radioactive iodine uptake test checks how much iodine the thyroid takes up from the blood.

NIDDK states you should not have a thyroid scan or a radioactive iodine uptake test if you are pregnant or breastfeeding. It also notes that for a nodule, a fine needle aspiration biopsy may be used to see whether the lump is cancerous or noncancerous.

A blood panel cannot see a lump. If you can feel something in your neck, say so to your doctor rather than relying on the report alone.

How to Prepare

No fasting is needed.

Tell your doctor if you are pregnant, taking oral contraceptives, using corticosteroids, or recovering from a serious illness, because NIDDK names all four as things that change thyroid hormone levels. This is information your doctor needs in order to read the result, not a reason to cancel the test.

If you already take thyroid medicine, ask the doctor who ordered the test whether to take your dose before the sample or after it, and keep to the same routine each time you are retested so results stay comparable.

What Happens During the Test

NIDDK describes it simply: a health care professional will draw blood from your arm and send it to a lab for testing, and your doctor will talk to you about your results. It takes under five minutes, and a brief sting or slight bruising afterwards is normal. In Lahore the sample can be collected at your home at no extra cost.

تھائیرائیڈ گردن کے سامنے موجود ایک چھوٹا سا غدود ہے جو دو ہارمون بناتا ہے، ٹی فور اور ٹی تھری۔ یہ ہارمون جسم میں توانائی کے استعمال کو کنٹرول کرتے ہیں اور تقریباً ہر عضو پر اثر ڈالتے ہیں، یہاں تک کہ دل پر بھی۔

فری تھائیرائیڈ ٹیسٹ اور عام تھائیرائیڈ ٹیسٹ میں فرق کیا ہے۔ خون میں کچھ پروٹین ٹی فور کے ساتھ جڑ جاتے ہیں۔ جڑا ہوا ٹی فور ذخیرے کے طور پر خون میں رہتا ہے، جبکہ فری یعنی آزاد ٹی فور وہ حصہ ہے جو جسم کے بافتوں تک پہنچ کر کام کرتا ہے۔ چونکہ ان پروٹینوں کی مقدار بدلنے سے فری ٹی فور پر فرق نہیں پڑتا، اس لیے بہت سے ڈاکٹر فری ٹی فور ناپنا بہتر سمجھتے ہیں۔

یہ بات خاص طور پر ان صورتوں میں اہم ہے۔ حمل کے دوران اور مانع حمل گولیاں کھانے سے تھائیرائیڈ ہارمون کی مقدار بڑھ جاتی ہے۔ شدید بیماری اور اسٹیرائیڈ دوائیں اسے کم کر دیتی ہیں۔ ایسی صورتوں میں عام ٹی فور رپورٹ غیر معمولی لگ سکتی ہے حالانکہ تھائیرائیڈ بالکل ٹھیک کام کر رہا ہوتا ہے۔ اسی لیے حمل میں عام طور پر فری تھائیرائیڈ ٹیسٹ ہی کروایا جاتا ہے۔

ٹی ایس ایچ کیا بتاتا ہے۔ ٹی ایس ایچ زیادہ ہونے کا مطلب عام طور پر تھائیرائیڈ کا کم کام کرنا ہوتا ہے، اور کم ہونے کا مطلب زیادہ کام کرنا۔ اگر ٹی ایس ایچ غیر معمولی آئے تو وجہ جاننے کے لیے کم از کم ایک اور ٹیسٹ ضروری ہوتا ہے۔

ٹیسٹ سے پہلے بھوکا رہنے کی ضرورت نہیں۔ ڈاکٹر کو ضرور بتائیں اگر آپ حاملہ ہیں، مانع حمل گولیاں لے رہی ہیں، اسٹیرائیڈ استعمال کر رہے ہیں، یا حال ہی میں شدید بیمار رہے ہیں۔ مرہم لیب میں اس ٹیسٹ کی قیمت پینتیس سو روپے ہے اور لاہور میں گھر سے نمونہ لینے کی سہولت مفت ہے۔

Final Thoughts

The free thyroid panel is not a premium version of the ordinary one. It measures a different thing, and it earns its price in specific situations: pregnancy, the contraceptive pill, steroid treatment, serious illness, or a total result that did not match how the patient looked. Outside those, TSH first and the standard panel behind it is usually what a doctor wants. Book what the prescription says, mention pregnancy and every medicine you take, and take the report back to the doctor who ordered it.
