Identification of pneumococcus facilitates the de-escalation of antibiotics. We compared a point-of-care immunochromatographic test that detects pneumococcal C-polysaccharide antigen (BINAX) performed in PF and urine to cultures (blood and PF) and 2 different PCR tests in PF of 79 children with empyema. BINAX in PF had 100% sensitivity and negative predictive value (NPV) to identify pneumococcus in children with empyema, compared with cultures (sensitivity 20.7%\/NPV = 68.8%) or PCR (sensitivity 96.5%\/NPV 98%). Urine BINAX demonstrated lower sensitivity (89%) and NPV (93%). BINAX in PF is superior to cultures (PF and blood), identifying pneumococcus in children with empyema. PCR has similar sensitivity and NPV to BINAX but is not readily available.<\/jats:p>","DOI":"10.1177\/00099228261421350","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T17:47:46Z","timestamp":1773251266000},"page":"626-634","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["BinaxNOW\n
