Method and instrument for collecting fluid in the oral cavity

摘要

A method of collecting a fluid in the oral cavity for quantifying D-glucose in the fluid in the oral cavity, wherein bacteria in the oral cavity have been preliminarily killed by a bactericide or the fluid is collected together with the bacteria to thereby inhibit the digestion of D-glucose by the bacteria; and a convenient instrument for collecting and recovering a fluid in the oral cavity wherein the fluid in the oral cavity is sterilized and collected with a hydrophilic absorbent containing a bactericide and then the absorbent is pressed to thereby recover the fluid having been absorbed thereby. Thus, specimens can be quickly collected and recovered.
