Devices, solutions and methods for sample collection

Some embodiments are directed to a bodily fluid sample collection device for the collection of naturally expressed bodily fluids and include a cap engageable with a tube to close a mouth of the tube. The cap includes a chamber for containing a reagent. The tube defines at least partly a sample collection space for receiving the naturally expressed bodily fluid. The cap comprises first and second cap portions relatively movable with respect to each other. The first and second cap portions are configured such that, responsive to engagement of the cap on the tube, one of the cap portions is caused to move integrally relative to the other cap portion to open the chamber and permit fluid communication between the chamber and the sample collection space. The reagent in the chamber is thereby permitted to mix with the bodily fluid in the sample collection space. A method of organizing and processing samples is also described. 些实施例涉及用于采集自然分泌的体液的体液样本采集设备，且包括与导管连接来封闭导管开口的盖子。所述盖子包括用于盛装试剂的内腔。所述导管至少部分限定了用于接收自然分泌的体液的样本采集空间
