Optimising pulmonary tuberculosis diagnosis in adults: diagnostic usefulness of stool gene xpert alone and in combination with sputum gene xpert at a referral centre in Northeastern Nigeria

Stool GeneXpert, particularly when combined with sputum GeneXpert, offers a promising alternative for diagnosing PTB, especially when sputum collection is difficult. The combined testing approach enhances diagnostic yield and may improve early detection and treatment outcomes for PTB in resource-limited settings. Further studies are warranted to confirm these findings and explore the broader applicability of stool GeneXpert.
