2. Description of the Related Art As a method for diagnosing gastrointestinal diseases such as colorectal cancer and gastric ulcer, feces are collected and fecal occult blood (hemoglobin in feces) is examined. Many proposals have been made for this fecal collection tool. Conventionally, in order to efficiently collect hemoglobin in feces, a simple and easy-to-handle stool consisting of a supporting member, a scraper formed of a soft material, a hard scraper holding member, and an extract holding container is easy. A sampling tool has been disclosed (see JP-A-6-148177).

[0003] In the measurement of fecal occult blood using the above-mentioned utensil, hemoglobin contained in a fecal sample is very small, so that a single collection cannot detect hemoglobin depending on the place and date and time of collection of feces, resulting in oversight. Therefore, in order to improve the accuracy, a sample is collected from a sample a plurality of times on different measurement dates. In this method, two stool collection tools are prepared, collected twice on different collection dates (hereinafter referred to as a 2-day method), and fecal occult blood is tested for each sample to improve the detection accuracy.

[0004]

With the conventional stool collection tool, it is easy to cope with one stool collection,
In the two-day method of processing samples, two samples of the same person are processed using containers of the same shape. Therefore, sample management and complicated processing operations are required until results are obtained. Has disadvantages. In particular, in the case of a large number of specimens obtained by performing a mass screening for colorectal cancer, the processing requires a great deal of labor and time, and it has been difficult to cope with automated measurement.
