采用一种新的抗原检测试剂盒NOW检测慢性中耳炎患者是否存在肺炎链球菌。NOW测试最初被设计为尿抗原测试，但在本研究中适用于中耳积液。对52例儿童中耳积液进行了研究。从10%的积液中培养肺炎链球菌。NOW测试在23%的积液中呈阳性，80%的培养阳性，17%的培养阴性。事实证明，NOW检测中耳积液中肺炎球菌抗原是一种快速、简单、可靠且相对便宜的方法。这项测试可能证明有价值的管理与急性中耳炎的儿童谁接受鼓膜穿刺术。
The presence of Streptococcus pneumoniae in chronic otitis media was determined with a new antigen detection kit, the NOW test. The NOW test was originally designed as a urinary antigen test but was adapted to middle-ear effusions for the present study. Middle-ear effusions from 52 children were studied. Streptococcus pneumoniae was cultured from 10 per cent of the effusions. The NOW test was positive in 23 per cent of the effusions, 80 per cent of culture positive and 17 per cent of culture negative effusions. The NOW test proved to be rapid, simple, reliable and relatively inexpensive for the detection of pneumococcal antigen in the middle-ear effusions. This test may prove valuable for the management of children with acute otitis media who undergo tympanocentesis.
