Sustainability in lateral flow testing is broader than material substitution. This article explores how material design, reagent strategy, manufacturing yield, performance testing, supply chain choices and at-source testing can reduce waste across the full lateral flow test lifecycle.

This guide to lateral flow assay development explains how to improve assay sensitivity and reproducibility through antibody screening, membrane selection, conjugate optimisation, strip design and process control.

Lateral Flow Assays (LFAs) may look simple, but successful development is far from straightforward. Behind reliable, consistent performance lies careful control of multiple interacting variables that can otherwise introduce hidden risk. Too often, development challenges surface late, when changes are costly, timelines slip and verification efforts fail. The difference between a smooth path to market and repeated re-design frequently comes down to early technical decisions and
