Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.

A bodily fluid collection device includes a needle part having a needle tube with a needle tip, and a capillary removably connected to a base end part of the needle tube in a longitudinal direction thereof on a side opposite to the needle tip. A method for collecting a bodily fluid using the bodily fluid collection device, and a method for collecting an aqueous humor using the bodily fluid collection device are also disclosed.

The present invention is directed to the parenteral procurement of bodily-fluid samples. The present invention is also directed to systems and methods for parenterally procuring bodily-fluid samples with reduced contamination from dermally-residing microbes. In some embodiments, a bodily-fluid withdrawing system is used to withdraw bodily fluid from a patient for incubation in culture media in one or more sample vessels. Prior to withdrawing bodily fluid into the one or more sample vessels for incubation, an initial volume of withdrawn bodily fluid is placed in one or more pre-sample reservoirs and is not used for the incubation in culture media.

Blood collection devices having a retractable needle are provided. Activation of the retraction mechanism causes release of propellant from a propellant chamber, which drives a retraction assembly carrying the needle into a body of the device.
