The free running asthma screening test (FRAST) was used to screen children in a state middle school during a normal physical education lesson. The test was conducted by the teachers with a general practitioner available via a radiopager. Of the 249 children attending the school, aged 8-12 years, 237 (95%) were tested. Twenty two (9%) children were known to have asthma, of whom 18 were tested. Thirty one children had a significant decrease (> 15%) in their peak expiratory flow rate (PEFR) after exercise. Six of these children were known to have asthma, indicating that their asthma treatment may be suboptimal. A further six children assessed clinically had false positive results. The 31 children with significant decreases in their PEFR were matched for age and sex with a control group of 30 children who were considered to have a normal result. Of the control group, one child had clinical asthma. In total, 19 (8%) new cases of asthma were identified, giving an overall prevalence of asthma in the school of 16%. These results indicate that it is feasible to screen schools for asthma using the FRAST. Children with undiagnosed asthma can be identified and the control of children with known asthma monitored.
在一所公立中学的正常体育课期间，采用自由哮喘筛查试验（FRAST）对儿童进行筛查。该试验由教师进行，一名全科医生通过传呼机随时提供支持。该校249名8至12岁的儿童中，237名（95%）接受了测试。已知有22名（9%）儿童患有哮喘，其中18名接受了测试。31名儿童运动后呼气峰值流速（PEFR）显著下降（>15%）。这些儿童中有6名已知患有哮喘，这表明他们的哮喘治疗可能未达到最佳效果。另有6名经临床评估的儿童结果为假阳性。将31名PEFR显著下降的儿童按照年龄和性别与30名被认为结果正常的儿童组成的对照组进行匹配。对照组中有1名儿童患有临床哮喘。总共识别出19例（8%）新的哮喘病例，该校哮喘的总体患病率为16%。这些结果表明，使用FRAST对学校进行哮喘筛查是可行的。可以识别出未确诊的哮喘儿童，并对已知患有哮喘的儿童的控制情况进行监测。
