ASCA - IgG antibody near me in Ranchi









The ASCA - IgG antibody test is a blood test that detects IgG antibodies against Saccharomyces cerevisiae, a type of yeast present in the digestive tract. This test helps differentiate between inflammatory bowel diseases (IBD), particularly Crohn’s disease and ulcerative colitis. The ASCA IgG test is widely available with Tata 1mg labs at an affordable price in Ranchi.
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 toward 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.








What does ASCA - IgG antibody measure?
The ASCA - IgG antibody test detects the presence of IgG antibodies produced by the immune system in response to Saccharomyces cerevisiae. These antibodies are usually present at very low levels in healthy individuals. Elevated IgG antibody levels suggest an abnormal immune reaction to yeast antigens, which is strongly associated with Crohn’s disease. While a positive result does not confirm the disease on its own, it provides supportive evidence when correlated with clinical signs and other laboratory tests. This test does not diagnose ulcerative colitis but can help differentiate between Crohn’s disease and ulcerative colitis, as ASCA positivity is far more common in Crohn’s disease.
