Do I need to be eating gluten before skin biopsy?

Hello I'm new. I have what I'm pretty sure is DH on my elbows and shins. Intensely itchy, red blisters that when scratched look like bites. Back in Sept 2015 I had them on both knees too. I have hives most day, have a burning sensation  and feel 'poisoned' I also have ibs and fibro. 

I came off gluten in Nov and the rash became less red and the itching stopped within a week, I now just have pale brown scars. My GP wanted to test me for celiac disease and asked me to go back on the gluten for 6 weeks but I lasted 7 days. Felt terrible. That was end of December, the rash started up again early Jan and it's worse than ever. I am going to see a dermatologist in the next week or two.

 

Would he be able to get a positive for DH if I've been off gluten or do I need to go back on it again? 

Many thanks.

Yes, you have to be eating gluten for the skin biopsy the same as you do for the blood panel.

"Many people with DH have no digestive symptoms and only about 40% of them have the positive blood tests (serology) for celiac disease. However, they almost always have the same, gluten-dependent intestinal damage as those with the more common symptoms of celiac disease."

A biopsy is done on a clear spot NEXT to an active lesion NOT ON one.

Omg! I was diagnosed with celiac in Nov. I had all the stomach problems. I ate gluten last week.. And have been having the hives ALL over. I just went to the dermatologist and took 2 biopsies in order to see if the hives are connected to DH.

i am suffering! I feel your pain. Any advice you could share with me?

katelyann, it doesn't matter if your hives are dh. You have celiac disease, no need to be dx'd with dh. You just have to be super careful not to get cross contaminated. Since your gluten exposure was assumedly only once last week then your biopsies will turn up negative for dh IF the derm took them correctly. You would have had to be eating gluten for a while for the biopsies to come up positive. You ought to take a look at hives & dh & compare because they are completely different things.

If it is not DH, then consider researching a histamine intolerance which may just be temporary.  I am not a doctor, but something to think about.  In any case, remaining gluten-free is critical.  Sorry to hear you were glutened!  :(

      Blood Test for Celiac wheat type matters?

      I'm not saying that some celiacs won't need it, but it should be done under a doctor's supervision because it can cause lots of problems in some people.

      Hello, just popped in my head to ask this question about medications and celiac? I have always had refurse reaction to meds since I can remember  of what little meds my body is able to tolerate. I was taking gabapentin 300mg for a week,  in past I believe 150? Any ways it amps me up not able to sleep, though very tired.However I did notice it helped with my bloating sibo belly.I hate that my body is that sensitive and medical doesn't seem to take seriously. Im STILL healing with my skin, eye, and now ms or meningioma ( will know in April  which)and dealing with this limbo nightmare. I did write my name, address ect on the reclamation but im not tech savvy and not sure if went through properly. I called my city representative in Stanislaus County and asked if theres a physical paper i can sign for proclamation for celiac and she had no clue about what I was saying, so I just said I'll go back on website.

      trents:  Why some can tolerate european bread but not american bread.     I take 600 mcg a day.  Right in the middle of the safe range.   Groups at Risk of Iodine Inadequacy Though though the NIH does not specifically list Celiac Disease in this group, they state: "Iodide is quickly and almost completely absorbed in the stomach and duodenum. Iodate is reduced in the gastrointestinal tract and absorbed as iodide [2,5]."  That would certainly include malabsorption of Iodine due to Celiac Disease with resultant Iodine Deficiency. Vegans and people who eat few or no dairy products, seafood, and eggs People who do not use iodized salt Pregnant women People with marginal iodine status who eat foods containing goitrogens Deficiencies of iron and/or vitamin A may also be goitrogenic [51] https://ods.od.nih.gov/factsheets/Iodine-HealthProfessiona   1
