Celiac Test Price in Pakistan: PKR 1,820 at Marham Lab

Coeliac disease is an autoimmune disorder that causes a serious reaction to gluten, a protein found in wheat, barley, rye and other grains. MedlinePlus explains that in coeliac disease the immune system makes antibodies whenever you eat gluten, and those antibodies attack the lining of the small intestine, damaging the villi that absorb nutrients from food. The tTG IgA test looks for those antibodies. At Marham Lab it costs PKR 1,820.

This is the single most important instruction on the page, and getting it wrong wastes the test entirely.

MedlinePlus states that if the test is being used to diagnose coeliac disease, you will need to continue eating foods with gluten for a few weeks before testing. Your provider will give specific instructions.

The reason is simple: the test detects the antibodies your body makes in response to gluten. Remove gluten and the antibodies fall, and the test can come back negative even though you have the disease.

This catches people constantly. Someone feels unwell, reads about gluten, cuts out roti and bread for a month, feels better, then asks for a test. That sequence produces an uninterpretable result. If you have already gone gluten free, tell your doctor before booking rather than after.

If the test is being used to monitor known coeliac disease, MedlinePlus notes no special preparation is needed.

MedlinePlus lists the common types.

Marham Lab lists tTG IgA at PKR 1,820 and tTG IgG at PKR 1,820. Book what your doctor wrote. If they asked for both, that is usually because they want to cover the IgA deficiency possibility.

MedlinePlus makes a distinction worth repeating, because the words get used interchangeably.

Digestive symptoms are common in gluten sensitivity and wheat allergy as well as coeliac disease, and they can look alike. But MedlinePlus states that coeliac disease is the only one of the three that damages the small intestine. That is why it needs diagnosing properly rather than self managing with a diet.

In children, MedlinePlus lists nausea and vomiting, abdominal bloating, constipation, chronic diarrhoea and foul smelling stool, weight loss or failure to gain weight, delayed puberty and irritable behaviour.

In adults, digestive symptoms include nausea and vomiting, chronic diarrhoea, unexplained weight loss, decreased appetite, abdominal pain, bloating and gas.

MedlinePlus also lists adult symptoms unrelated to digestion, and these are the ones most often missed: iron deficiency anaemia, an itchy rash called dermatitis herpetiformis, mouth sores, bone loss, depression or anxiety, fatigue, headaches, missed menstrual periods, and tingling in the hands or feet.

An unexplained [iron deficiency anaemia](/labs/tests/serum-ferritin-test-price) that keeps returning despite supplements is a recognised reason to think about coeliac disease.
