Feces sampling container, and fecal assay method and analyzer

A method for assaying a fecal suspension which is formed by dissolving feces in a feces-dissolving liquid contained in a feces sampling container, and extracted from the feces sampling container, the method comprising:

• an extraction step of extracting the fecal suspension;
• a mixing step of adding and mixing a diluting solution into/with the extracted fecal suspension in a predetermined amount, the diluting solution having a different concentration from that of the feces-dissolving liquid with respect to a specific pigment;
• a detection step of detecting the concentration of the specific pigment to be changed in response to the mixing of the diluting solution;
• and
• a determination step of determining the adequacy of the extraction amount of the fecal suspension in accordance with the detected concentration of the specific pigment.

An analyzer comprising:

• an extractor for extracting from a feces sampling container a fecal suspension which is formed by dispersing feces in a feces-dissolving liquid contained in the feces sampling container;
• a diluter for adding and mixing a diluting solution into/with the extracted fecal suspension in a predetermined amount, the diluting solution having a different concentration from that of the feces-dissolving liquid with respect to a specific pigment;
• a detector for detecting the concentration of the specific pigment to be changed in response to the addition of the diluting solution;
• and
• a determinator for determining the adequacy of the extraction amount of the fecal suspension in accordance with the detected concentration of the specific pigment.
