SHBG Test Price in Pakistan: Rs 1,610 at Marham Lab

SHBG stands for sex hormone binding globulin. MedlinePlus explains that it is a protein made mostly in your liver which binds to sex hormones such as testosterone and estrogen, and helps control how much of these hormones are active in your body. At Marham Lab an SHBG test costs Rs 1,610, reduced from Rs 2,300.

Why This Test Exists at All

MedlinePlus sets out the logic plainly, and it is the whole reason a doctor orders SHBG.

All the sex hormones in your blood are either bound to proteins or unbound, which is called free. MedlinePlus states that free sex hormones work with your tissues, helping with bone and muscle growth and reproductive health, while sex hormones bound to proteins such as SHBG cannot work with your tissues.

A [total testosterone test](/labs/tests/testosterone-test-price) measures both the free and the bound hormone together. MedlinePlus is explicit that this test cannot tell the difference between the two types and cannot tell your provider how much of your testosterone is free for your body to use. It then makes the point that sends people to this page:

You could have symptoms from too little or too much free testosterone even when your total testosterone level is normal.

That is the gap SHBG fills. By measuring the binding protein, your doctor can estimate how much testosterone is actually available to your tissues. MedlinePlus notes SHBG and total testosterone tests may be done at the same time.

How to Read a Low or High SHBG

MedlinePlus explains that your provider usually looks at SHBG alongside a total testosterone result to estimate how much free testosterone is in your blood. The direction is counterintuitive, so it is worth setting out carefully.

So a low binding protein means more active hormone, not less. This is the part most people get backwards.

What Causes Low SHBG

MedlinePlus lists these.

• Hypothyroidism, an underactive thyroid
• Type 2 diabetes or insulin resistance
• Obesity or being very overweight
• Overuse of steroid medicines or anabolic steroids
• Cushing's syndrome
• In females, polycystic ovary syndrome (PCOS)

MedlinePlus adds that it is also normal for SHBG levels to decrease with older age, as the production of sex hormones also decreases.

Two of these deserve emphasis in Pakistan. Insulin resistance and type 2 diabetes are extremely common here, and anabolic steroid use in gyms is widespread and rarely declared. Both lower SHBG, and both are things your doctor needs to know about rather than discover.

What Causes High SHBG

MedlinePlus lists liver disease, hyperthyroidism meaning an overactive thyroid, certain eating disorders, use of estrogen containing medicines such as hormone therapy for menopause or birth control pills in females, and decreased production of sex hormones in males.

Because the liver makes SHBG and the thyroid influences it, an unexpected SHBG result sometimes sends a doctor to check the [liver](/labs/tests/lft-test-price) or the [thyroid](/labs/tests/thyroid-test-price) rather than the gonads.

Why Women Are Tested

MedlinePlus says that in adult females the test helps when symptoms may be caused by too much testosterone. It lists them.

• Too much hair growth on the face and body
• Deepening of voice
• Menstrual periods that are not regular, or no periods at all
• Acne
• Weight gain
• Fertility problems

PCOS is the common thread. MedlinePlus states SHBG can help diagnose hormonal disorders such as PCOS, and is careful to add that an SHBG test alone cannot diagnose this condition though it can help providers reach a diagnosis when paired with other test results. It also notes SHBG is used to monitor treatment for PCOS.

A full PCOS workup here usually includes [LH](/labs/tests/lh-test-price), [FSH](/labs/tests/fsh-test-price), [DHEA sulfate](/labs/tests/dhea-s-test-price) and [free testosterone](/labs/tests/free-testosterone-test-price) alongside this one.

Why Men Are Tested

MedlinePlus says that in adult males the test helps when symptoms may be caused by too little testosterone, and lists low sex drive, difficulty getting an erection, fatigue or loss of muscle mass, and fertility problems.

It notes you may need this test particularly if results from a total testosterone test did not explain your symptoms. That is the clearest signal for booking it: a normal total testosterone alongside symptoms that persist.

SHBG in Children

This is a use most people have never heard of and it is worth knowing.

MedlinePlus explains that SHBG levels are normally high in all children, and that these high levels prevent sex hormones from affecting body tissues. If SHBG levels are low, children may start puberty too early. It lists helping diagnose early puberty in children among the reasons a provider orders the test.

If a child is showing signs of early puberty, this is a test a paediatric endocrinologist may ask for.

How to Prepare

MedlinePlus states you do not need any special preparations for an SHBG test. No fasting is required.

Medicines are what matter here. MedlinePlus says to tell your provider about all medicines, vitamins and supplements you take, and names hormone containing medicines specifically: birth control pills, estrogen therapy and anabolic steroids can affect SHBG levels. Do not stop taking any medicine unless your provider tells you to.

If you use gym supplements or have ever taken an anabolic steroid, say so. It changes how the result should be read, and MedlinePlus lists steroid overuse as a direct cause of low SHBG.

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 adds that your provider may order other tests to check whether your hormones are in balance with each other.

ایس ایچ بی جی ایک پروٹین ہے جو زیادہ تر جگر بناتا ہے۔ یہ ٹیسٹوسٹیرون اور ایسٹروجن جیسے جنسی ہارمونوں کے ساتھ جڑ جاتا ہے اور یہ طے کرتا ہے کہ ان میں سے کتنے ہارمون جسم میں فعال رہیں گے۔

یہ ٹیسٹ کیوں ضروری ہے۔ خون میں موجود جنسی ہارمون یا تو پروٹین کے ساتھ جڑے ہوتے ہیں یا آزاد۔ صرف آزاد ہارمون جسم کے بافتوں پر کام کرتے ہیں، جڑے ہوئے ہارمون کام نہیں کر سکتے۔ عام ٹوٹل ٹیسٹوسٹیرون ٹیسٹ دونوں کو ملا کر ناپتا ہے اور یہ نہیں بتا سکتا کہ کتنا حصہ جسم استعمال کر سکتا ہے۔ اسی لیے ایسا ہو سکتا ہے کہ ٹوٹل ٹیسٹوسٹیرون نارمل ہو مگر علامات پھر بھی موجود ہوں۔

ایک بات الٹی لگتی ہے مگر یاد رکھنے کی ہے۔ ایس ایچ بی جی کم ہونے کا مطلب ہے کہ زیادہ ٹیسٹوسٹیرون آزاد اور قابل استعمال ہے۔ اور ایس ایچ بی جی زیادہ ہونے کا مطلب ہے کہ کم ٹیسٹوسٹیرون بافتوں تک پہنچ رہا ہے۔

ایس ایچ بی جی کم ہونے کی وجوہات میں تھائیرائیڈ کا کم کام کرنا، ٹائپ ٹو ذیابیطس یا انسولین کی مزاحمت، موٹاپا، اسٹیرائیڈ دواؤں کا زیادہ استعمال، اور خواتین میں پی سی او ایس شامل ہیں۔ پاکستان میں ذیابیطس اور جم میں اسٹیرائیڈ کا استعمال دونوں عام ہیں، اس لیے یہ باتیں ڈاکٹر کو ضرور بتائیں۔

خواتین میں یہ ٹیسٹ عام طور پر چہرے اور جسم پر زیادہ بال، ماہواری بے قاعدہ ہونا، کیل مہاسے، وزن بڑھنا اور بانجھ پن کی صورت میں کروایا جاتا ہے۔ یاد رکھیں کہ اکیلا ایس ایچ بی جی ٹیسٹ پی سی او ایس کی تشخیص نہیں کر سکتا، یہ دوسرے ٹیسٹوں کے ساتھ مل کر مدد دیتا ہے۔

ٹیسٹ سے پہلے بھوکا رہنے کی ضرورت نہیں۔ البتہ مانع حمل گولیاں، ایسٹروجن کی دوائیں اور اینابولک اسٹیرائیڈ رپورٹ پر اثر ڈالتے ہیں، یہ سب ڈاکٹر کو بتائیں۔ مرہم لیب میں اس ٹیسٹ کی قیمت سولہ سو دس روپے ہے اور لاہور میں گھر سے نمونہ لینے کی سہولت مفت ہے۔

Final Thoughts

SHBG is the test that explains a normal total testosterone in someone who clearly has symptoms. It works by measuring the protein that decides how much hormone is free to act, so a low result means more active testosterone and a high result means less. It is read with a total testosterone rather than alone, it cannot diagnose PCOS by itself, and the two things most worth declaring before the sample are the contraceptive pill and anything taken at the gym.
