    Abstract:

    A sensitive method for measuring haemoglobin in gastric contents using the rate of change of optical density of a mixture of orthotolidine and hydrogen peroxide in the presence of haemoglobin, is described. The method can measure the blood normally lost in 10 min from the gastric mucosa.

    Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...
