Abstract: A “one-step”, single-handed device for obtaining small, precise volumes of fluid from animals is able to quickly and easily draw a fluid sample. The device comprises an extraction component and a collection component that are coupled together and disposed along a grip handle. The user manipulates the device so as to initiate the extraction of the fluid, and then collect the fluid in a component that can quickly and easily be removed from the grip handle—allowing the handle to be re-loaded and used again and again. The extraction component may comprise a hypodermic needle and the collection component may comprise a pre-calibrated pipette, where the pipette is positioned directly behind the needle and will thus draw the extracted fluid into a pre-sized chamber within the pipette.
