Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by symptoms like abdominal pain, bloating, and changes in bowel habits. While there is no single blood test that can directly diagnose IBS, laboratory testing plays a valuable supporting role in identifying potential dietary triggers that may worsen symptoms.

The Role of Blood Testing in IBS Management
IBS is typically diagnosed based on symptoms and clinical criteria. However, blood tests are fundamental for ruling out other conditions and identifying food sensitivities that may contribute to symptom flare-ups. Many individuals with IBS find that certain foods trigger their symptoms, and testing can help pinpoint these problematic foods.
Other Relevant Tests
Food Specific IgG Lima Bean
Though not entirely understood, there's a possible connection between elevated Food Specific IgG levels and IBS. Some people with IBS have been found to have high levels of IgG antibodies related to certain foods, including lima beans, which might trigger symptoms and worsen their condition.
