Commonly used methods for gut microbiota testing currently

Currently, common methods for intestinal microbiota testing include fecal examination, biopsy, genetic testing, and others.

1. Fecal Examination

This is the most common method for intestinal microbiota testing. It involves collecting a stool sample from the individual and sending it to a pathology laboratory for bacterial culture, followed by analysis of the types and proportions of microbial populations present in the stool.

2. Biopsy

This is an invasive procedure but offers relatively higher accuracy. Medical professionals perform tissue sampling during endoscopic examination, typically taking specimens from areas such as the distal colon and rectum. These samples undergo standard pathological culture and compositional analysis to observe the composition and distribution of gut microbiota.

3. Genetic Testing

Intestinal microbiota can also be influenced by genetic inheritance. By sequencing specific genes, preliminary screening and diagnosis of gut microbiota can be achieved, which helps guide subsequent diagnostic evaluations and the development of targeted treatment plans.

In addition to the above medical tests, other methods for assessing intestinal microbiota may include serological testing and similar approaches.
