Descripción

Hereditary food intolerances are common and can seriously affect quality of life. This genetic test studies specific variants in the genes responsible for the digestion of lactose and fructose:

Lactose intolerance: occurs due to reduced activity of the enzyme lactase, which is necessary to break down lactose, the sugar in milk. Its deficiency causes symptoms such as bloating, diarrhea, abdominal pain, or gas after consuming dairy products.

Hereditary fructose intolerance: is a rare but serious disorder caused by mutations in the aldolase B gene, which prevent proper metabolism of fructose. It can cause severe abdominal pain, vomiting, hypoglycemia, and if untreated, liver and kidney problems.

Unlike acquired intolerances, these genetic forms accompany the individual throughout life. Early detection allows for dietary adjustments and prevention of major complications.

¿Is it suitable for me?

This test is for you if:
• You have recurring digestive discomfort after consuming dairy, fruits, or other products with fructose or lactose.
• You have a family history of lactose or fructose intolerance.
• You suffer from chronic symptoms (diarrhea, gas, abdominal pain) without an apparent cause.
• You have had inconclusive results in other tests.
• You want to rule out hereditary predisposition in children with early symptoms.

Sample type: Blood

How does it work?

Frequently Asked Questions

Does a positive result confirm intolerance?

Indicates genetic predisposition, not a clinical diagnosis.

Is it possible to do at any age?

Yes, genetic predisposition does not change over time.

Can I take this test if I already avoid dairy or fructose?

Yes, diet does not influence DNA.

How are the results interpreted?

They must be reviewed by a specialist.

¿Qué diferencia hay entre intolerancia genética y funcional a la lactosa?

La intolerancia genética (primaria) se debe a variantes en el gen LCT que reducen la producción de lactasa de forma permanente. La funcional o secundaria aparece como consecuencia de enfermedades intestinales y puede ser reversible. El test genético intolerancia lactosa detecta la forma primaria hereditaria.

Requires fasting?

No, it is not necessary.
