The chemical tests used to determine blood in faeces and urine have not been recommended for determining blood in gastric contents, since highly acidic samples may give false-negative reactions. Based on model studies this article states that, in most cases, ordinary chemical tests for faecal blood may also prove useful for determining blood in gastric materials.
用于检测粪便和尿液中血液的化学检测方法,并不推荐用于检测胃内容物中的血液,因为高酸性样本可能会产生假阴性反应。基于模型研究,本文指出,在大多数情况下,普通的粪便潜血化学检测方法也可能有助于检测胃内容物中的血液。
