About this trial

This observational diagnostic validation study aims to evaluate the clinical performance of novel lateral flow and microfluidic-based technologies for the detection of upper and lower respiratory tract infections in children and adults presenting with respiratory symptoms in Uganda, Ethiopia, and Senegal. The main questions it aims to answer are:

1. whether the novel multiplex lateral flow tests and point-of-care microfluidic platform demonstrate sufficient sensitivity and specificity for detecting respiratory pathogens compared with standard laboratory reference methods, and 2. whether these technologies are feasible and usable in low-resource clinical settings.

Participants presenting with suspected respiratory tract infections as part of routine clinical care will provide respiratory and blood samples for diagnostic testing and biobanking, and demographic and clinical information will be collected during a single study visit. Some adult participants and community stakeholders will also complete surveys or interviews regarding the acceptability of biobanking and diagnostic implementation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥ 6 months

Fever (axillary temperature ≥37.5°C) or history of fever

New acute cough episode

Shortness of breath

Disqualifiers

Refusal or inability to provide informed consent/assent

Refusal to provide study samples

Severe chronic medical conditions or mental incapacity that, in the opinion of the clinician, would interfere with study participation

Hospitalisation within the previous 2 weeks for reasons unrelated to the current respiratory symptoms

Trial population

The study will enrol symptomatic children aged 6 months to 17 years and adults aged ≥18 years of both sexes presenting to participating hospitals and health centres with suspected upper or lower respiratory tract infections (RTIs). Participants will be recruited in Uganda, Ethiopia, and Senegal from outpatient and inpatient healthcare settings. Eligible participants will present with at least two symptoms consistent with respiratory infection, such as fever, acute cough, shortness of breath, tachypnoea, or loss of smell and/or taste. Participants (or parents/guardians for minors) will provide written informed consent prior to enrolment.

Trial outcomes

Primary outcomes

1

Upper respiratory tract infections (URTIs) cohort (sub-study 1)

To determine the diagnostic performance, including sensitivity and specificity of the multi-LFT using a nasopharyngeal (NP) swab, with results interpreted via both visual detection and an Android tablet as a reader.

Time frame
From April 2025 to May 2026

Secondary outcomes

1

Lower Respiratory Tract Infections - Point-of-Care Instrument cohort (sub-study 2)

To validate the clinical performance (sensitivity and specificity) of a POC platform that performs pathogen detection (bacteria, fungi) using microfluidic-LAMP isothermal amplification and quantification of host-response biomarkers, using a bead-based immunoassay, by comparing its results to those of reference standard methods (benchtop PCR and ELISA, respectively).

Time frame
April 2025 to May 2026
