ASCA - IgA antibody near me in Chennai
The ASCA - IgA antibody test is a blood test that detects IgA antibodies against Saccharomyces cerevisiae, a yeast naturally present in the digestive tract. This test helps differentiate between types of inflammatory bowel disease (IBD), particularly Crohn’s disease and ulcerative colitis. The ASCA IgA test is widely available with Tata 1mg labs at an affordable price in Chennai.
Detecting ASCA-IgA helps doctors differentiate Crohn’s disease from ulcerative colitis, two major forms of IBD that affect different regions of the gastrointestinal tract and often need different treatment approaches. The test is recommended for patients with gastrointestinal symptoms such as long-standing diarrhea, abdominal pain, unexplained weight loss, or rectal bleeding, especially if the diagnosis is unclear.
No special preparation is needed for getting the ASCA - IgA antibody test done. You can eat and drink as per your daily routine.
