What is a ASCA-IgA SACCHAROMYCES CEREVISIAE?

The **ASCA-IgA (Saccharomyces cerevisiae) test** is a blood test used to detect IgA antibodies against *Saccharomyces cerevisiae*, a type of yeast. These antibodies are often associated with autoimmune conditions, particularly Crohn’s disease, and can help differentiate it from ulcerative colitis. The test is performed by drawing a blood sample from a vein, which is then analyzed in the laboratory using immunoassay techniques to measure the presence and levels of ASCA-IgA antibodies.
