[Correspondence] Implementation of cholera RDTs: bridging laboratory precision and field reality

The comprehensive study by Javier Perez-Saez and colleagues, published in The Lancet Microbe, demonstrates a remarkable performance of cholera rapid diagnostic tests (RDTs) in Bangladesh, revealing 93·5% sensitivity and 97·3% specificity through rigorous Bayesian latent class analysis.1 The methodological advancement in accounting for imperfect reference standards represents a key contribution of the study, particularly considering the global rollout of 1·2 million RDTs across 14 high-risk countries initiated in 2024 under the Gavi diagnostic support programme.
