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 blood sequestration device includes an inlet path, an outlet path, a sequestration chamber, and a sampling channel. The sequestration chamber is connected with the inlet path by a junction and is configured to receive a first portion of blood through the inlet path. The sequestration chamber has a vent that allows air to be displaced by the first portion of blood, the junction being configured to inhibit a return to the inlet path of any of the first portion of blood received by the sequestration chamber. The sampling channel is connected between the inlet path and the outlet path, and configured to convey subsequent amounts of blood between the inlet path and the outlet path after the first amount of blood is received by the sequestration chamber.
