Does IBS show as inflammation on blood test?
The CRP test is a general test – it does not specify where inflammation in the body may be or what the cause is. Generally, patients with IBS have a normal CRP result, which would show that there is no CRP present in the blood.
Median hs-CRP levels in the IBS group were significantly higher than in HC (1.80; interquartile range, 0.7 to 4.04 mg/L vs. 1.20, interquartile range, 0.5 to 2.97 mg/L respectively, P<0.006). Levels were highest in IBS-D patients with greater disease severity.
The researchers found that the blood tests identified anti-Cdtb and anti-vinculin antibodies successfully with greater than 90% accuracy. These antibodies were elevated in participants with IBS compared with participants that did not have IBS.
Irritable bowel syndrome (IBS) is considered a functional bowel disorder, not an autoimmune disease. However, certain autoimmune diseases produce symptoms similar to IBS and you can have an autoimmune disease and IBS at the same time.
As evidenced by patients who develop postinfectious IBS, infective gastroenteritis could cause systemic inflammation and altered microbiome diversity, which in turn perpetuates a cycle of chronic, low-grade, subclinical inflammation.
Stool markers such as calprotectin or lactoferrin have emerged as new diagnostic tools to detect intestinal inflammation. They are noninvasive, rapid, simple and low in cost.
Inflammatory bowel disease is a group of autoimmune diseases that run the spectrum from ulcerative colitis to Crohn's disease. Inflammatory bowel disease is a dysregulation in the body where the immune system attacks the bowel and causes inflammation.
As many as one in four people with coeliac disease were previously misdiagnosed with IBS as many of the symptoms for IBS such as bloating, stomach pains or cramps, diarrhoea or constipation and feeling exhausted are the same as the symptoms of coeliac disease.

Does IBS mean you have a weak immune system?
So, while IBS and associated symptoms can cause your immune system to weaken, troubled digestion can contribute to an overactive immune system. Inflammation, such as that present in the gut with IBS, can influence the immune system and cause the it to over-react.
IBS can develop after a severe bout of diarrhea caused by bacteria or a virus. This is called gastroenteritis. IBS might also be associated with a surplus of bacteria in the intestines (bacterial overgrowth).

- Ulcerative Colitis.
- Crohn's Disease.
- Celiac Disease.
- Abdominal bloating, swelling, cramping, gas or pain.
- Constipation (infrequent stools that may be hard and dry)
- Diarrhea (frequent loose stools)
- Feeling that bowel movements are incomplete.
- Feeling uncomfortably full after eating a normal-sized meal.
- Frequent bathroom emergencies.
- Mucus in the stool.
Can a colonoscopy detect IBS? No, a colonoscopy can't detect IBS, a condition also known as irritable bowel syndrome.
There's Now a Way to Diagnose IBS With a Simple Blood Test.
ibs-smart measures the levels of two validated IBS biomarkers, anti-CdtB and anti-vinculin. These biomarkers are elevated in a majority of IBS patients with diarrheal symptoms and can diagnose diarrhea-predominant or mixed-type IBS (IBS-D or IBS-M).
What does the test measure? ibs-smart measures the levels of two antibodies, anti-CdtB and anti-vinculin, that are known to be elevated in patients with post-infectious IBS. Anti-CdtB is developed from an immune response to the toxin, CdtB, released by the most common bacteria that cause food poisoning.
- Systemic lupus erythematosus.
- Sjögren's syndrome -- a disease that causes dry eyes and mouth.
- Scleroderma -- a connective tissue disease.
- Rheumatoid arthritis -- this causes joint damage, pain, and swelling.
- Polymyositis -- a disease that causes muscle weakness.
When an inflammatory bowel disease is present, a blood test will show an increased white blood cell count, which may indicate inflammation. A blood test can reveal if a person has a Helicobacter Pylori infection, which is an indicator of stomach ulcers and could put a person at greater risk of stomach cancer.
