Gut Health

Genetic Testing of the gastrointestinal microbiota.

Product manual
The profiling of human gut microbiota can depict personal health information that is hidden in the gut microbiomes.

Majority of the microbes that live within humans are located in the gut. These microbes are very important for nutrient metabolism and absorption as well as immune system regulation. the gut is also a very complex neural network which often refers to as the Second Brain. gut microbes are also related to numerous physical and mental diseases according to the current research.

The genetic testing using next-generation sequencing (NGS) technology can profile bacteria in your gut. This data is then compared with more than 150,000 strains of bacteria in the global bacteria database to confirm the type and proportion of microbes in your intestine.

This test report analyzes the proportion of beneficial and harmful bacteria which are associated with constipation, diarrhea, and gastrointestinal nutrient absorption capacity. After analyzing your gut microbiota, we categorized them into five categories; Excessive harmful microbe, gastrointestinal sensitive, functional degradation, nutritional disorders, daily health maintenance which provides you an appropriate health maintenance program using probiotics.

Non-invasive home sampling

The detection of human gut microflora is sampled at home in a non-invasive and simple manner. Genetic information regards to the gut microbiome can be obtained through the simple collection of feces by sampling rods.

Bioinformatics analysis

  • Since feces can reflect the conditions in the intestine, the test is performed by the collection of fecal samples. Bacteria DNA in the fecal sample is then extracted.
  • Sequencing the 16S rRNA variable segments of bacterial DNA through high-throughput sequencing technology.
  • Performing bioinformatics analysis on the sequencing results to profile microbiome in the gut. By combining the sequencing results, HGT’s proprietary reference database and curated information from international journal literature, gut health status can therefore be depicted from the gut microbiome analysis.

Overall Intestinal analysis

Testing Interpretation :
According to the proportion of beneficial and harmful bacteria, constipation, diarrhea, flatulence, and gastrointestinal nutrient absorption capacity, we categorized your microbiota according to the specific categories ( Excessive harmful microbe, gastrointestinal sensitive, functional degradation, nutritional imbalance, daily health maintenance); And provides you an appropriate health plan.

Beneficial and harmful microbiota analysis

Testing Interpretation :
According to the proportion of good bacteria: bifidobacterium, lactobacillus etc., Clostridium difficile, Helicobacter pylori bacteria-related disease assessment; constipation, flatulence, diarrhea, colorectal cancer, and allergic condition analysis. Microbiota assessment: biodiversity indicator (more is better), aerobic bacteria index (less is better).

Functional microbiota analysis

Testing Interpretation :
Akk bacteria ratio : anti-inflammatory, hypoglycemic, hypolipidemic, anti-atherosclerotic, etc.
Recent dietary assessment : evaluate the proportion of lipid-consuming bacteria and meat-consuming bacteria. A high value indicates excessive intake.
Nutritional elements : The intestinal bacteria can metabolize, absorb and synthesize vitamins, metal elements, and essential amino acids.
Calories absorption capacity : This kind of strong absorption capacity means more intake

Eight indicators of microbiota balance

Significance :
The composition of the microbiota is very complex and there is no certain standard. Microbiota profiling is a relative indicator of health.
