Clinical Performance of the Mp1p Enzyme Immunoassay in 889 Study Participants, Including 372 Participants With Culture-proven Talaromycosis and 517 Non-talaromycosis Control Participants

ODcutoff = 0.5	Talaromycosis Cases	Non-talaromycosis Controls	Sum
TmAg positive OD ≥0.5	TP 321	FP 10	331
TmAg negative OD <0.5	FN 51	TN 507	558
Sum	372	517	889
Diagnostic Features	Diagnostic Values, No. (%)	(95% CI)
Sensitivity	321/372 (86.3%)	(82.3%–89.5%)
Specificity	507/517 (98.1%)	(96.3%–99.0%)
Positive likelihood ratio	${\displaystyle \frac{0.863}{1-0.981}=45}$
Negative likelihood ratio	${\displaystyle \frac{1-0.863}{0.981}=0.14}$

Abbreviations: FN, false negative; FP, false positive; OD, optical density; TmAg, Talaromyces marneffei antigen; TN, true negative; TP, true positive.
