Lactase deficiency revealed
Non-invasive rapid test to reveal lactose intolerance
A rapid and reliable combination of LAMP and Lateral Flow Assay technologies.
Developed in collaboration with Fraunhofer IZI, one of Europe’s leading applied-research institutes
Understanding our biotechnology: a diagnostic challenge
Lactose intolerance affects a significant portion of the global population according to large meta-analysis. Diagnosis remains a challenge for several reasons, most existing tests are either quite invasive or highly expensive and require highly skilled staff.
Eralydix’s solution fills the gap for a non-invasive, easy to use and rapid solution to screen lactose intolerance.
Biotechnology: A rapid test for lactose intolerance screening
Eralydix develops a innovative solution combining 2 well proven technologies LAMP (Loop-Mediated Isothermal Amplification) and LFA (Lateral Flow Assay) to reveal lactose Intolerance in 30 minutes.
Our approach is:
Rapid and easy to use
Fully non-invasive (buccal swab sample)
Significantly shorten the time from diagnosis to patient management
Advancing medical diagnostics through scientific innovation
Our solution brings strong value across multiple dimensions:
🧬 Medical value: more accurate diagnosis of lactose intolerance
