[Chemical determination of blood in gastric contents].
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.
