New DNA blood test could speed up heart infection diagnosis
NCT ID NCT06309680
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new blood test that looks for bacterial DNA to quickly identify the germ causing infective endocarditis, a serious heart valve infection. Current methods take up to 5 days, delaying the right antibiotics. The study will enroll 200 adults with suspected endocarditis and compare the new test's accuracy to standard blood cultures.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The sample will be a consecutive group of patients from hospitals in the trial referred to BHC Endocarditis MDT meeting for management of their disease. Approximately 150 cases are referred to the Endocarditis MDT each year and we reject the diagnosis of endocarditis in 17% of patients by the time of discharge (the cases are highly selected by the time they are referred). The study is designed to be practicable and applicable to a real-world group of patients. Thus, we will study all patients who give consent and have possible or definite endocarditis as per the determination of the clinical Endocarditis MDT. In practice, by the time treatment is completed the number left in the possible endocarditis group is very small (\<5%) although when the patient is first referred approximately 20% are in that category. As the disease progresses down its course, the correct diagnosis quickly becomes apparent - especially after surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients with possible or confirmed IE referred to BHC Endocarditis MDT * Age \>18 * Able and willing to give informed consent Exclusion Criteria: * Patients whose diagnosis of endocarditis is "rejected" by the MDT. If this occurs after entry to the study samples will be discarded and the patient informed. * Patients who have been treated with intravenous antibiotics for more than 7 days at the time of study entry.
