50 YO Male Recently Diagnosed with Celiac Disease

[ekelsay]

Today, I received the results of my Tissue Transglutaminase (tTG) Ab, IgA test. I am not sure how to interpret the results. I have left a message for the doctor that requested the test but have not heard back. The results stated that the normal range is from 0.00 - 4.99 FLU. My results came back at 92.08. Is this concerning? This seems extremely high for someone who has reached the age of 50 before finding out he has celiac disease. 

The reason that I was administered the test in the first place is due to bloating issues that started about a year ago. I met with a Gastroenterologist and after a short question and answer session she wanted to test me for celiac disease and a bacteria test via the H. Pylori Breath Test. She seemed more concerned with the fact that I am a healthy male suffering from Anemia. Is it possible the anemia could be a result of celiac disease? I have been on an iron supplement for the better part of 5 years.

Welcome to the forum community, @ekelsay!

Yes, your tTG-IGA score is strongly positive for celiac disease. There are other antibody tests that can be run when diagnosing celiac disease but the tTG-IGA is the most popular with physicians because it combines good sensitivity with good specificity, and it is a relatively inexpensive test to perform.

The onset of celiac disease can happen at any stage of life and the size of the score is not necessarily an indicator of the progress of the disease. It is likely that you you experienced onset well before you became aware of symptoms. It often takes 10 years or more to get a diagnosis of celiac disease after the first appearance of symptoms. In my case, the first indicator was mildly elevated liver enzymes that resulted in a rejection of my blood donation by the Red Cross at age 37. There was no GI discomfort at that point, at least none that I noticed. Over time, other lab values began to get out of norm, including decreased iron levels. My PCP was at a complete loss to explain any of this. I finally scheduled an appointment with a GI doc because the liver enzymes concerned me and he tested me right away for celiac disease. I was positive and within three months of gluten free eating my liver enzymes were back to normal. That took 13 years since the rejection of my blood donation by the Red Cross. And my story is typical. Toward the end of that period I had developed some occasional diarrhea and oily stool but no major GI distress. Many celiacs do not have classic GI symptoms and are "silent" celiacs. There are around 200 symptoms that have been associated with celiac disease and many or most of them do not involve conscious GI distress.

Via an autoimmune process, gluten ingestion triggers inflammation in the villous lining of the small bowel which damages it over time and inhibits the ability of this organ to absorb the vitamins and minerals in the food we ingest. So, that explains why those with celiac disease often suffer iron deficiency anemia, osteoporosis and a host of other vitamin and mineral deficiency related medical issues. The villous lining of the small bowel is where essentially all of our nutrition is absorbed. So, yes, anemia is one of the classic symptoms of celiac disease.

One very important thing you need to be aware of is that your PCP may refer you to a GI doc for an endoscopy/biopsy of the small bowel lining to confirm the results of the blood antibody testing. So, you must not begin gluten free eating until that is done or at least you know they are going to diagnose you with celiac disease without it. If you start gluten free eating now there will be healing in the villous lining that will begin to take place which may compromise the results of the biopsy.

In the Europe the new protocol for making a celiac disease diagnosis in children is if their tTg-IgA (tissue transglutaminase IgA) levels are 10 times or above the positive level for celiac disease.

According to the latest research, if the blood test results are at certain high levels that range between 5-10 times the reference range for a positive celiac disease diagnosis, it may not be necessary to confirm the results using an endoscopy/biopsy:

• Blood Test Alone Can Diagnose Celiac Disease in Most Children and Adults
• TGA-IgA at or Above Five Times Normal Limit in Kids Indicates Celiac Disease in Nearly All Cases
• No More Biopsies to Diagnose Celiac Disease in Children!

There are other things that may cause elevated tTg-IgA levels, but in general a reaction to gluten is the culprit:
