摘要: The invention includes devices and methods for obtaining samples of blood or other bodily fluids with reduced levels contamination. Fluid obtained from a subject may be contaminated by skin cells, bacteria, fungi, viruses, phages, their respective RNA, DNA, and/or undesirable molecules, disinfectants. A first amount fluid is injected the through an distal needle proximal penetrates portion device having sequestration chamber sub-atmospheric pressure therein. fluid, containing contaminants, deposited into chamber. then moved second collection container. Because contaminants are removed sample, analysis diagnosis subject's condition becomes more reliable accurate. Additional can used to obtain relatively uncontaminated cell culturing vessels.
