Abstract

Fine needle aspiration biopsy (FNAB) has been shown to be the diagnostic procedure of choice for superficial lymphadenitis in tuberculosis endemic regions.


We conducted a retrospective laboratory-based study to determine the bacteriological yield of clinically suspected mycobacterial tuberculous lymphadenitis following FNAB in adults, and specifically HIV-positive patients, to determine the need for the introduction of automated nucleic acid amplification tests (NAATs) such as the Xpert MTB/RIF assay as the initial diagnostic modality.
A diagnostic yield of 80% was achieved, significantly higher in HIV-positive v. HIV-negative patients (84% v. 52%, respectively; p<0.001).
The results justify using automated NAATs such as the Xpert MTB/RIF assay as the initial diagnostic modality to expedite management in HIV-infected patients.
