ASCA - IgG antibody

Saccharomyces cerevisiae is a normally harmless yeast found in the body and the environment. In some people, however, the immune system reacts by producing antibodies against it. These antibodies, known as anti-Saccharomyces cerevisiae antibodies (ASCA), are commonly linked with Crohn’s disease. Detecting ASCA-IgG in the blood helps differentiate Crohn’s disease from ulcerative colitis. While both conditions fall under the category of IBD, they affect different regions of the gastrointestinal tract and often require distinct treatment approaches.

The ASCA - IgG antibody test is recommended for individuals showing gastrointestinal symptoms such as persistent diarrhea, abdominal pain, weight loss, or rectal bleeding, especially when the clinical features do not clearly point towards either ulcerative colitis or Crohn’s disease. It is also valuable in cases with atypical or overlapping IBD symptoms where additional diagnostic information is needed. By identifying elevated ASCA-IgG levels, clinicians can tailor treatment more precisely to the patient’s condition.

No special preparation is needed for getting the ASCA - IgG antibody test done. However, be sure to inform the doctor about any medications or supplements being taken, as they may affect the test results. 

Lab test results may vary across different laboratories. Abnormal test results require expert interpretation. Therefore, never try to self-medicate based solely on these results. Always consult a doctor for a proper understanding of the test resul
