Automated Bubble Sweat Test Diagnostics

Insights into the project documentation

Aims of this collaborative project

This project aims to automate and standardize the analysis required for a diagnostic test for cystic fibrosis.

Our partner Teresinha Leal from the UCLouvain in Brussels has established and improved a non-invasive version of the imaging based sweattest with a linear charateristic identifying heterozygous as half responders useful to study genotype-phenotype correlation of rare CFTR mutations.

Another advantage of the new image-based test is that it has proven to be able to detect improved levels of CFTR function in patients treated with CFTR modulators. However, a severe practical limitation of the test is the manual image analysis (80 images/test), which is labour-intensive and can take 6 hours per test.

The Automated Bubble Sweat Test Diagnostics – AutoBuSTeD aims at overcoming the practical limitation of the new sweat test due to the labour cost of its data analysis.


Our project is funded by the Christiane-Herzog-Stiftung via the "Forschungsförderpreis für wissenschaftliche Nachwuchsförderung 2018" for our project proposal "Verbesserung der individuellen Bestimmung der CFTR-Restfunktion durch automatisierte Bildanalyse von beta-adrenerg-abhängiger Schweisssekretion"

Project partners

The software is being developed transnationally and tested by our project partner with a cohort from Brussels ( Identifier NCT03584841).
