Chitobioside IgG Antibody, Serum or Plasma, by Immunoassay
This test measures IgG antibodies in your blood that bind to chitobioside, a small carbohydrate structure. It is usually ordered as part of an antibody panel used in digestive and intestinal evaluations.
["The result reflects the amount of chitobioside-reactive IgG in your blood, and it is interpreted by your clinician along with other tests and your symptoms."]

What Is Being Measured
Chitobioside is a short sugar (disaccharide) fragment. Some people produce antibodies that recognize this and similar sugar structures. This test detects IgG-type antibodies in serum or plasma that bind to chitobioside.
Why This Test May Be Ordered
Your clinician may order this test as part of a broader antibody panel when evaluating digestive complaints, unusual reactions to certain foods, or other immune-related concerns. It is rarely used on its own and is best interpreted with the rest of the panel.
How the Test Is Done
A blood sample is collected from a vein, usually in your arm. The laboratory uses an immunoassay method to measure how much antibody binds to the chitobioside target. Results are typically reported as a concentration or titer.
What the Results Mean
A higher result means more of this antibody was detected; a lower result means less. Results do not, by themselves, diagnose a specific condition and are affected by age, other illnesses, and medications. Your clinician will interpret the number together with your history and other laboratory findings.
Reference range
Reference values are laboratory-specific and should be interpreted in conjunction with clinical findings. Generally, results are reported as positive, negative, or equivocal based on the assay cut-off value.N/A
No special patient preparation required. Fasting is not necessary.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
