Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Diagnosis / Prognosis - Concentrated urine with Xpert Ultra
Diagnosis / Prognosis - Stool with Xpert Ultra

Experimental: intervention arm - The intervention arm for this trial consists of HIV patients with TB testing performed regardless of presence of TB symptoms. Testing will be done on expectorated sputum, stool and concentrated urine with Ultra, and urine with AlereLAM.

To fulfil exploratory objectives, we will also collect and store 2x tongue swabs for molecular TB diagnostic assay (Xpert Ultra and/or LumiraDx) testing, blood for testing with CRP, and urine samples which will be stored for retrospective FujiLAM testing and analysis.

No intervention: control arm - The control arm for this trial will consist of patients managed according to the current WHO recommended TB testing practices for HIV positive inpatients (as of Q1 2020).

TB testing will be done as follows:

Sputum Ultra performed whenever the patient has cough, fever, weight loss over night sweats and/or Ultra performed on any tissue (including lymph nodes) from patients with clinical suspicion of extrapulmonary TB.

and/or: Urine Alere TB-LAM performed if patients have signs and symptoms of TB (pulmonary and/or extrapulmonary), or with advanced HIV disease, or who are seriously ill, or else irrespective of signs and symptoms of TB, but combined with a CD4 cell count of less than 200 cells/mm .
