Stools from 88 consecutive patients in acute geriatric wards were tested for occult blood by four common commercial methods. The Peroheme and Haemostix tests were found too sensitive for general use, the Okokit and Haemoccult tests being preferable. Positive tests were correlated with anaemia in 27 patients, iron deficiency in 26, iron deficiency anaemia in 15, non-anaemia in 52, non-iron deficiency in 43 and with absence of both in 27. Such testing has been considered unnecessary in anaemic patients without gastrointestinal symptoms.
采用四种常见的商业方法，对急性老年病房中88例连续患者的粪便进行潜血检测。结果发现，Peroheme和Haemostix检测对于一般用途过于敏感，而Okokit和Haemoccult检测则更为可取。27例患者的检测呈阳性与贫血相关，26例与缺铁相关，15例与缺铁性贫血相关，52例与非贫血相关，43例与非缺铁相关，27例与两者均无相关。对于没有胃肠道症状的贫血患者，这种检测被认为是不必要的。
