Thirty percent of infected people do not receive treatment due to failure to receive diagnostic testing or being lost to follow-up between testing and availability of results.\n\nObjective:\n\nTo refine and field-validate a point-of-care (POC) finger stick blood test for use worldwide to triage for active TB.\n\nEligibility:\n\nPersons aged 12 - 70 years with symptoms suggestive of TB disease\n\nStudy design:\n\nParticipants will be screened with:\n\nMedical history Physical exam HIV test, diabetes screening Blood (finger stick and venous), sputum and urine collection Chest X-ray TB positive participants will receive treatment from the National TB Program at Community Health Centres and clinics.', 'detailedDescription': 'This study aims to make widely available an inexpensive, easy to use point-of-care finger stick test to triage patients presenting with signs and symptoms consistent with active TB. From previous experience in EDCTP-funded studies, approximately 30% of such patients test positive for TB, with the vast majority having respiratory illnesses other than active TB, including acute upper or lower respiratory tract infections or exacerbations of chronic obstructive pulmonary disease. The proposed finger stick test is designed, with the aim of use, as a TB rule out test such that resources required for further testing can be used with more efficiency.\n\nThe majority (60%) of suspected TB cases are seen at public health facilities, however many facilities in high TB prevalence areas still do not have access to efficient TB diagnostic services due to logistical and financial constraints that plague these settings. Currently available diagnostics include radiological and microbiological testing, though each has drawbacks for use in primary care facilities.\n\nThe TriageTB consortium will be evaluating combinations of biomarkers in samples from African and Non-African individuals suspected of having TB in order to identify the optimal biomarker signature for global identification of patients with high likelihood of TB. A device has been developed, which measures a combination of biomarkers in finger stick capillary blood and has been validated in the laboratory setting. Previous EDCTP-funded projects identified a promising 6-marker biosignature which has been shown to have potential for being reduced to a 3- or 4- marker signature. The 3-marker signature has the added benefit of potential for treatment monitoring applications. A triage test as proposed here would significantly speed up and streamline diagnostic approaches in resource-limited settings.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '15 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Participants are recruited from known TB endemic areas across three African countries.', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
