Gut microbiome

The gut microbiome is highly complex and consists of a vast number of microorganisms, primarily bacteria. It's a networked organ connected to various parts of the body and can thus have a significant impact on health and well-being.

C-FISH , NL-Lab is able to fully measure the gut microbiome and identify it correctly with 96% accuracy. This provides better insight into the situation and what can be done to restore balance.

We offer gut microbiome research for:

The layout of our offer for practitioners

Dysbiosis packages

Traditional dysbiosis research only indicates whether the gut microbiome is in balance (eubiosis) or out of balance (dysbiosis). At NL-Lab, we have developed an improved dysbiosis model. Our model recognizes four different types of dysbiosis, each with its own characteristics and potential treatments.

These affordable packages are very suitable as an initial inventory of the intestinal microbiome or for monitoring over a longer period.

PRO-Dysbiosis

This package provides insight into whether the gut microbiome is in balance, based on the two largest groups of bacteria in the gut microbiome. If there is an imbalance (dysbiosis), you will receive information about the type of dysbiosis, the degree of dysbiosis, the sample characteristics, and treatment recommendations for that specific type of dysbiosis.

The general gut microbiome packages

The general gut microbiome packages measure 100% of the gut microbiome and identify 96%. This gives you a complete picture of the gut microbiome's composition. There are three different packages, each with increasing detail.

PRO-Expert (can only be ordered by practitioners)

This package offers everything from the Pro Basic package, plus additional bacterial analyses (Akkermansia and Faecalibacterium prausnitzii) and insights into the role of the gut microbiome on: probiotic function, mucus function, intestinal membrane protection, intestinal wall permeability, and possible inflammation of the intestinal wall.
Extended description

PRO-Master (can only be ordered by practitioners)

Our most comprehensive package, in addition to the Pro Expert package, offers even deeper insights into intestinal membrane protection, intestinal wall permeability, and any intestinal wall inflammation (slgA, calprotectin). In addition, butyrate production, LPS production, oxalate reduction, and sulfate reduction are measured.

Package composition as of October 15, 2025:

The specific gut microbiome studies

These studies focus on a specific part or function of the gut microbiome.

These studies can be ordered separately or as a supplement to other gut microbiome packages.

Extensive parasite research

If you experience recurring intestinal complaints, there's a good chance a parasitic infection is the cause. Our research is the most comprehensive parasite study available and identifies the 16 species responsible for over 95% of parasitic intestinal infections worldwide.

Quality of digestion

Complete insight into the quality of digestion. This test is suitable for (suspected) osmotic diarrhea, steatorrhea, pancreatic insufficiency, and impaired liver function. The test includes determination of fat, carbohydrate, protein, and water content, as well as pancreatic elastase in the stool.

Gluten sensitivity

Provides an indication of food intolerance, specifically celiac disease. The test includes determination of anti-transglutaminase, anti-gliadin, and histamine levels.

Yeasts & Molds

This kit tests for elevated yeast and/or mold levels and their activity. The possible presence of Candida albicans and Aspergillus is specifically noted in the report.

The gut microbiome studies on request

These studies focus on a specific part or function of the intestinal microbiome and can only be requested after consultation with NL-Lab.

If you are interested, please contact us.

Probiotic testing

We can test probiotics for the presence of bacterial species, bacterial numbers and the activity of the cells present.

Pro Biotica Personal

The results of this study can be used to request personalized probiotics from third parties and provide insight into the composition and activity of the gut microbiome. You will also gain insight into the degree and type of dysbiosis, the diversity of the microbiome, the permeability of the intestinal wall, and any inflammation of the intestinal wall.

Bowel-related disorders

Our PRO-Expert and PRO-Master packages include additional studies that map the influence of the gut microbiome on gut-related disorders.

This concerns conditions that are directly related to the intestines (proximal conditions such as IBS, leaky gut, colic) and conditions that run across the various intestinal axes (distal conditions such as depression, asthma, eczema).

NB: These tests provide insight into the potential contribution of the gut microbiome to the development or maintenance of a specific condition. The test results are not a diagnosis and should be assessed by the healthcare provider.

The gut-related disorders

  1. SIBO
  2. Type 2 diabetes
  3. Colic
  4. Leaky gut
  5. Obesity
  6. IBS
  7. Crohn's/Colitis
