A fasting insulin test costs PKR 2,415 at Marham Lab, down from PKR 3,450. MedlinePlus interprets insulin only alongside blood glucose: high insulin with normal glucose suggests insulin resistance, while high insulin with low glucose means something different. You will probably need to fast 8 to 12 hours, and MedlinePlus says to stop biotin supplements at least a day before.

What is the Insulin (Fasting) test?
Insulin is a hormone made by your pancreas. MedlinePlus explains that it moves blood glucose from your bloodstream into your cells where it is used for energy, and that normally insulin and glucose rise and fall together: glucose goes up after you eat, the pancreas releases more insulin, the insulin lets glucose into your cells, and both come back down. A fasting insulin test measures how much insulin is in your blood. At Marham Lab it costs PKR 2,415.
This Result Means Nothing Without a Glucose Reading
The single most important thing to understand before booking.
MedlinePlus sets out interpretation entirely in pairs of insulin and glucose:
Insulin
Glucose
What it may mean
High
Normal or a little above normal
You may have insulin resistance
High or normal
Low
Hypoglycaemia from too much insulin, possibly an insulinoma, Cushing's syndrome, or too much insulin taken for diabetes
Low
High
The pancreas may not be making enough insulin, possibly type 1 diabetes or pancreatitis
Read down that table and you will see the same insulin value can mean three different things depending on the glucose beside it. An insulin number on its own is close to uninterpretable.
So if your doctor ordered fasting insulin, check whether a fasting glucose or [HbA1c](/labs/tests/hba1c-test-price) is on the same form. If it is not, ask. Booking insulin alone usually means paying twice.
Fast for 8 to 12 Hours, and Stop Biotin
MedlinePlus states you will probably need to fast for 8 to 12 hours before the test, and that your provider will tell you how to prepare.
There is a second instruction that catches people out. MedlinePlus says that if you take biotin supplements, also called vitamin B7, or supplements containing biotin, you need to stop them for at least a day before the test. Biotin is a standard ingredient in hair, skin and nail supplements, which many people do not think of as medicine at all. Check the label rather than assuming.
Do not stop any prescribed medicine without speaking to your provider.
What It Is Used For
MedlinePlus lists the uses, and names the primary one clearly.
Finding the cause of hypoglycaemia, meaning low blood glucose. This is the main reason for doing insulin testing
Diagnosing insulin resistance
Guiding treatment decisions in type 2 diabetes, including whether someone needs to take insulin
Monitoring how well pancreatic islet cell transplantation is working
That first line is worth noticing, because most people booking this test in Pakistan are thinking about insulin resistance rather than low blood sugar.
On Insulin Resistance
MedlinePlus explains insulin resistance as cells not responding well to insulin, so they cannot easily take glucose from the blood. The pancreas makes more insulin to compensate, which can keep glucose in a healthy range for a while, but over time the pancreas may wear out, leading to prediabetes and then type 2 diabetes.
MedlinePlus lists conditions that raise your risk: prediabetes, type 2 diabetes, polycystic ovary syndrome, heart disease, and acanthosis nigricans, which is dark, thick, velvety skin around the neck or armpits.
That skin sign is worth knowing because it is visible and commonly dismissed as dirt or pigmentation, particularly in younger patients.
Symptoms of Low Blood Glucose
MedlinePlus lists mild to moderate hypoglycaemia as sweating, feeling shaky or jittery, an abnormal heart rate or rhythm, confusion, dizziness, headache and hunger.
It adds that severe hypoglycaemia can cause fainting and seizures, and is a serious condition needing medical treatment right away. That is an emergency rather than a reason to book a test.
A Test Often Paired With This One
MedlinePlus notes an insulin test is often done with a C-peptide test, because the pancreas releases equal amounts of insulin and C-peptide at the same time, and C-peptide stays in the blood longer. That makes C-peptide a more accurate way to measure how much insulin the pancreas is actually producing, particularly in someone already taking insulin.
What Happens During the Test
A trained phlebotomist takes a small blood sample from a vein in your arm using a small needle. In Lahore the sample can be collected at your home, which makes an early fasting appointment considerably easier to keep.
Final Thoughts
Fasting insulin is a useful test in the right pairing and a waste of money on its own. Make sure a glucose or HbA1c is being measured at the same time, fast properly for 8 to 12 hours, and stop biotin supplements a day beforehand. And if the real question is diabetes risk rather than hypoglycaemia, ask your doctor whether HbA1c would answer it more cheaply.
Common questions
Usually not. MedlinePlus explains insulin results entirely in combination with blood glucose: high insulin with normal glucose suggests insulin resistance, high insulin with low glucose suggests hypoglycaemia from excess insulin, and low insulin with high glucose suggests the pancreas is not producing enough. The same insulin number means different things depending on the glucose beside it. Check whether a glucose or HbA1c is on your prescription, and ask if it is not.
MedlinePlus states you will probably need to fast for 8 to 12 hours before an insulin test, and that your provider will tell you how to prepare. There is a second instruction people miss: if you take biotin supplements, also called vitamin B7, or any supplement containing biotin, MedlinePlus says to stop them at least a day beforehand. Biotin is common in hair, skin and nail supplements. Never stop a prescribed medicine without asking your provider.
It is one of them, though MedlinePlus names finding the cause of hypoglycaemia, meaning low blood glucose, as the main reason for doing insulin testing. Diagnosing insulin resistance is listed as a use. MedlinePlus describes insulin resistance as cells not responding well to insulin, with the pancreas compensating by making more, which can hold glucose in a normal range for a time before prediabetes and then type 2 diabetes develop.
MedlinePlus describes it as dark, thick, velvety skin around the neck or armpits, and lists it among the conditions that raise your risk of insulin resistance, alongside prediabetes, type 2 diabetes, polycystic ovary syndrome and heart disease. It is worth knowing because it is visible and often mistaken for dirt or ordinary pigmentation, especially in younger people, when it is actually a reason to discuss testing with a doctor.

انسولین ایک ہارمون ہے جو لبلبہ بناتا ہے۔ یہ خون میں موجود شکر کو خلیوں تک پہنچاتا ہے تاکہ جسم کو توانائی ملے۔
سب سے اہم بات۔ اکیلی انسولین کی رپورٹ کا کوئی واضح مطلب نہیں نکلتا۔ اسے ہمیشہ شوگر یعنی گلوکوز کی رپورٹ کے ساتھ پڑھا جاتا ہے۔ انسولین زیادہ اور شوگر نارمل ہو تو انسولین ریزسٹنس کا امکان ہوتا ہے۔ انسولین زیادہ اور شوگر کم ہو تو مطلب مختلف ہوتا ہے۔ اس لیے نسخہ دیکھیں کہ شوگر کا ٹیسٹ بھی ساتھ لکھا ہے یا نہیں۔
تیاری کی دو باتیں۔ ٹیسٹ سے پہلے آٹھ سے بارہ گھنٹے بھوکا رہنا ہوتا ہے۔ اور اگر آپ بایوٹن یعنی وٹامن بی سیون والا سپلیمنٹ لیتے ہیں، جو بالوں اور ناخنوں کی دواؤں میں عام ہوتا ہے، تو کم از کم ایک دن پہلے بند کر دیں۔ ڈاکٹر کی تجویز کردہ دوا اپنی مرضی سے بند نہ کریں۔
ایک اور بات۔ گردن یا بغل کے گرد جلد کا گہرا اور موٹا ہو جانا انسولین ریزسٹنس کی علامت ہو سکتی ہے۔ اسے میل سمجھ کر نظرانداز نہ کریں۔ مرہم لیب میں اس ٹیسٹ کی قیمت چوبیس سو پندرہ روپے ہے۔
