Abstract:
1. A method for filtering a sample using a sample collecting container that includes: a sample collection part storing a collected liquid sample and having an opening; a plug member provided so as to hermetically seal the opening; a filter member provided in the sample collection part, for filtering the sample collected in the sample collection part; and a sample storage part for storing a sample filtered by the filter member, the internal pressure thereof being reduced in advance, wherein after collecting a sample in the sample collection part using a vacuum blood collection needle, the sample is filtered by a pressure difference between the sample collection part and the sample storage part, while the plug member is pierced by a communication needle having a communication flow channel to establish communication between the sample collection part and the exterior, thereby elevating the internal pressure of the sample collection part, wherein a communication between an internal space of the sample collection part and atmosphere occurs (1) after collecting the sample in the sample collection part and (2) due to the piercing of the plug member by the communication needle having the communication flow channel.
