Claim by claim

The source study was found, but the study's evidence could not be profiled, so these claims couldn't be checked.

Claim 1 of 6Not checkedResearchers say the study is the largest-ever study of pooled tuberculosis testing, carried out by Start4All, a partnership led by LSTM with the Stop TB Partnership and research partners in seven high-burden countries.View evidenceHide evidence

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 2 of 6Not checkedThe study found that pooled sputum testing, which examines samples from several people in a single molecular test cartridge, halves the number of cartridges needed to make successful diagnoses.View evidenceHide evidence

Claim 5 of 6Not checkedBetween November 2023 and February 2025, more than 14,000 people with TB symptoms in Bangladesh, Brazil, Cameroon, Kenya, Malawi, Nigeria and Vietnam took part, and pooled testing used just over 7,000 cartridges instead of about 14,000, a 51% reduction, with cost per test falling from nearly $8 to less than $4.View evidenceHide evidence
