The Revolutionary Breath Test C13 for lactose intolerance!


Why revolutionary?

The breath test session that can normally be found in hospitals and clinics goes to investigate the presence of hydrogen in the breath, takes 4 hours and a quantity of lactose of 25 grams must be ingested. This new method of analysis does not exploit hydrogen but carbon 13, it is more precise and allows to carry out all the examination in 2 hours and with only 15 grams of lactose! This results in less discomfort, cramps or diarrhea.

Moreover, with this solution proposed by us EXCLUSIVELY, you can carry out the test safely at home, without worrying about having to go to a public toilet, in case of need, during the test.

How does the exam work?

Once you open the package you will discover a jar with lactose powder* , some tubes and instructions. The proof is simple. You must first exhale (blow) into 2 of the 6 tubes provided. Then prepare the drink with lactose powder * and 200 ml of water and drink it. Finally exhale every 30 minutes into one of the remaining tubes.

When the material is ready, just send a message to the number indicated in the instructions and a courier will pick it up directly at home. The result will be delivered to you by email within 7 days.

The features of the Lactosolution Breath Test C13:

  • Possibility to do it at home, when you are more comfortable and at the time you want
  • High sensitivity (>98%) or very low probability of false negatives
  • High specificity (>98%) i.e. very low probability of false positives
  • Executable in pregnancy
  • Faster than the common hydrogen H2 Breath Test
  • Less annoying
  • Suitable for children
  • Economic
  • Safe

The C13 Breath Test, compared with the H2 Breath Test, has peculiar characteristics:

  • It is less prone to interference from other pathologies. It is not affected either by the production of H2 or by a possible bacterial overgroth
  • The 13C test lasts only two hours because the enzyme lactase is located right in the membrane of the brush hemlock in the duodenum and the appearance of 13CO2 occurs already at 60 Minutes. The H2 Breath Test must last 4 hours as per the Italian guideline (in many centers the H2 Breath Test is done in 3 hours and therefore causes false negatives).
  • 13C-BT is a direct and semi-quantitative method whose result is directly related to the amount of metabolized lactose, that is, the activity of the enzyme lactase. The H2 Breath Test is an indirect method, which investigates the formation of secondary gases. A low intestinal bacterial load in the colon, in case of diarrhea and frequent discharge, can give a low H2 peak, even less than 20 ppm and therefore cause false negatives with the H2 breath Test method.


Symptoms can arise one to a few hours after ingestion of lactose, and are the ones that most characterize lactose intolerance:

  • Abdominal pain
  • Nausea
  • Headache
  • Abdominal bloating
  • Diarrhea or constipation
  • Fatigue
  • Skin rashes
  • Meteorism
  • Flatulence 


  • Fasting for a minimum of 8 hours. You can drink only non-carbonated water.
  • You should not smoke, sleep, or exercise at least half an hour before the test and during the test.  
  • You must not have had diarrhea recently.
  • You should seek advice from your doctor if you are taking any medications.
  • The test should be performed at least one week after stopping the use of laxatives and/or lactic ferments.

* Harmless lactose substrate that can be administered for the performance of the breath test examination. In the absence of updated national guidelines it is sold as a RUO (Research Use onl prodotto
