Middle, Jonathan G
Abstract
In response to a report that the Abbott Architect direct testosterone immunoassay was affected by dehydroepiandrostenedione sulphate (DHEAS) cross-reactivity, this study investigated the effect of DHEAS on other testosterone methods using a UK National External Quality Assessment Scheme (UK NEQAS) for steroid hormones special distribution.
