What is a positive igg value for celiac disease?
The cut-off value for a positive tTG-IgG test may vary slightly between different laboratories and testing methods. Generally, an IgG value above a specific cut-off is considered positive and may indicate an increased likelihood of celiac disease.
However, it's important to note that a positive tTG-IgG test result alone does not confirm celiac disease. Further testing, such as an upper endoscopy with biopsy of the small intestine, is usually recommended to establish a definitive diagnosis of celiac disease. Your doctor will evaluate your overall clinical presentation, laboratory findings, and biopsy results to make an accurate diagnosis.
