Of the 501 TB suspects who provided blood for TB blood culture testing, 394 were sputum smear-negative and eligible for the analysis (Figure 1); 63.7% were female with a median age (IQR) and CD4 cell count (IQR) of 32 (28–39) years and 106 (24–308) cells/mm3, respectively (Table 1). Here, CD4 is linked to tuberculosis.
