Who can benefit from our solution?

Lactose intolerance can affect anyone, often without being diagnosed.
Explore real-life situations where early and accurate testing can make a real difference.

A baby drink the milk

👶 Mike

Mike is only a few months old.
After every feeding, he cries for hours. His parents try everything — changing formula, adjusting routines — but nothing seems to work.

What if it’s not just “normal baby discomfort”?

Lactose intolerance can appear early, and without clear diagnosis, families are left searching for answers.

🧒 Lucas

Lucas is 10 years old.
He often complains about stomach pain at school, struggles to focus, and feels tired more than he should. Teachers think he’s distracted. His parents think it’s just a phase.

But these recurring symptoms aren’t random.

Early identification of lactose intolerance could completely change his daily life — at school and beyond.

👩 Jeanne

Jeanne has learned to live with it.
Bloating, discomfort, avoiding certain foods… it’s part of her routine now. She never really questioned it.

Yet, what she doesn’t know is that nearly 80% of medications contain lactose as an excipient — potentially worsening her symptoms every single day.

What if the problem isn’t just diet, but something deeper that’s never been tested?

🏃 John

John is a dedicated athlete.
He trains hard, eats clean, and tracks everything — yet something feels off. Digestive issues during training, unexplained fatigue, inconsistent performance.

When every detail matters, even a hidden intolerance can make the difference.

Identifying lactose intolerance could be the missing piece holding him back.

Our genetic testing technology

Eralydix focuses on identifying lactase deficiency at the genetic level, providing a direct understanding of the condition.

Our test detects:

🧬 genetic markers associated with lactose intolerance

🧪 the presence or absence of lactase persistence

🔍 the underlying cause of digestive symptoms

This allows healthcare professionals to adapt a diagnostic solution strategies more effectively against lactose intolerance.

Detecting the genetic cause of lactose intolerance

Lactose intolerance is often managed through dietary adjustments without precise diagnosis.

Traditional methods, such as breath tests, can be uncomfortable, time-consuming and sometimes inaccurate.

As a result, many patients follow inappropriate or unnecessary treatments.

There is a critical need for a reliable and rapid diagnostic solution to reveale effective lactose intolerance.

Our Eralydix’s lactose intolerance diagnostic FAQ

🧬 What is Eralydix’s lactose intolerance diagnostic?

Eralydix develops a genetic-based approach to better understand and diagnose lactose intolerance at its root cause. Unlike traditional methods, our solution focuses on identifying lactase deficiency through genetic insights, enabling more accurate and reliable results.

🧪 How is this solution different from traditional lactose intolerance tests?

Traditional tests, such as breath tests, measure symptoms rather than the underlying cause. Eralydix’s diagnostic solution targets the genetic origin of lactose intolerance, providing a more precise and long-term understanding of the condition.

⚡ Who is concerned by this solution?

Lactose intolerance affects about 68% of the global population (95% CI: 64–72), with important regional differences. It is more common in Asia (64%) and Sub-Saharan Africa (63%), while lower rates are observed in Western Europe (28%), Latin America (38%), and North America (42%). Eastern Europe shows an intermediate prevalence of 47%, highlighting geographical variation.
