Current guidance to recognise maternal sepsis includes assessment of physiological markers, however normal physiological changes of pregnancy can hinder the diagnosis of sepsis. This study investigated the utility of routine clinical variables, including laboratory tests, in screening for maternal sepsis.</div></div><div><h3>Methods</h3><div>Patients considered at risk of obstetric sepsis were recruited into a single centre cohort study.
