However, molecular assays including the GeneExpert TPB/RIF ultra (Cepheid, CA, USA), now recommended by the World Health Organization, provide significantly improved sensitivity on extra‐pulmonary samples and were successfully utilized in a similar recently published case of peritoneal tuberculosis 7 . Other new diagnostic tests including interferon gamma (sensitivity 93%; specificity 99%) and adenosine deaminase (sensitivity 100%; specificity 97%) show promise for differentiating tuberculosis ascites from non‐tuberculous ascites 8,9 …”
