Genetic intolerance test for lactose and fructose
A simple and definitive genetic test that lets you know if you have predisposition to lactose or fructose intoleranceThese are two of the most frequent causes of digestive discomfort. With a simple blood test, you can find out if your body has difficulty digesting these sugars and improve your digestive well-being with clear and reliable information.

Detects genetic predisposition to lactose and fructose intolerance
It helps identify the origin of recurring digestive symptoms.
Simple test using blood analysis
Definitive results, valid for life
Clear report to guide dietary changes
What is the test of Genetic intolerance to lactose and fructose?
It is a DNA test that analyzes genetic variations related to:
- Primary hypolactasia (genetic intolerance to lactose).
- Predisposition to fructose malabsorption or hereditary fructose intolerance.
These genetic variations influence your ability to properly break down and absorb these sugars. Unlike other tests, Your genetics don't change.Therefore, this study only needs to be done once in a lifetime.
What symptoms may indicate lactose or fructose intolerance?
Lactose or fructose intolerance can cause symptoms such as:
Abdominal bloating and gas.
Diarrhea or constipation
Abdominal pain or discomfort after eating.
Slow or heavy digestion.
Nausea after consuming dairy products or fruit/juices.
Fatigue or general malaise associated with meals.
It can also be helpful if you have been experiencing digestive discomfort for a long time without a clear diagnosis.
What exactly does this test analyze?
1. Genetic lactose intolerance (hypolactasia)
Evaluate gene variants related to the lactase persistence or absence, the enzyme responsible for digesting lactose.
When this enzyme decreases, symptoms appear after consuming milk, yogurt, or dairy products in general.
2. Fructose intolerance
Analyze genetic variants related to the ability to absorb and metabolize fructose, present in fruits, honey, sweeteners, soft drinks and processed products.
3. Definitive results
Genetic testing does not change over time, so it is useful for:
- To guide diets and treatments safely.
- Confirm predisposition.
- Rule out intolerance of genetic origin.
Benefits of taking this test
A clearer diagnosis
It helps you understand if your digestive discomfort is related to a genetic factor.
No preparation or special diet is required.
Unlike other intolerance tests, It doesn't depend on what you've eaten..
Perfect complement to digestive studies
If you have already had a SIBO test, microbiota test or food intolerance test, this study adds useful genetic information.
Improve your well-being
With the results, you can adjust your diet more precisely with the help of a healthcare professional.
How is the test performed?
Step 1:
Request the test
Visit your Ribera Lab center for a simple blood draw.
Step 2:
Sample collection
A small blood sample is obtained without any prior preparation.
Step 3:
Genetic analysis in laboratory
The laboratory studies your DNA to detect variants associated with lactose and fructose intolerance.
Step 4:
Report and results
You will receive a clear report indicating whether there is a genetic predisposition and providing guidelines.
Results analysis
Results for lactose
- Genetic predisposition present: It indicates primary hypolactasia, that is, a higher probability of intolerance.
- Absent predisposition: low probability of genetic intolerance.
Results for fructose
- Associated genetic variations: increased risk of malabsorption.
- No changes detected: low probability of intolerance of genetic origin.
Important:
The test detects predispositionHowever, the clinical decision must be integrated with your symptoms, history, and professional assessment.
