A biological fluid collection device configured to collect blood, comprising: a housing (13, 20, 22) having a superior surface, an inferior surface, a proximal end, a distal end, an inlet channel, and an outlet channel, wherein a portion of the superior surface of the housing (13, 20, 22) defines a cavity having a cavity superior surface, and wherein a portion of the inferior surface of the housing (13, 20, 22) defines a sacrificial flow channel, the sacrificial flow channel comprising: a middle channel having a first middle channel end, a second middle channel end, and defining a slot, the first middle channel end in fluid communication with the inlet channel, the middle channel extending from the inlet channel in a first direction; a first arcuate channel having a first arcuate channel distal end and a first arcuate channel proximal end, the first arcuate channel distal end in communication with the second middle channel end; and a second arcuate channel having a second arcuate channel distal end and a second arcuate channel proximal end, the second arcuate channel distal end in communication with the second middle channel end; a first venting plug disposed in the first arcuate channel proximal end; and a second venting plug disposed in the second arcuate channel proximal end, wherein each of the first arcuate channel and the second arcuate channel are in communication with the inlet channel but are spaced apart from the inlet channel by the middle channel, characterized in that: the first arcuate channel extends from the second middle channel end in a second direction, the second arcuate channel extends from the second middle channel end in the second direction, and the sacrificial flow channel increases the time before blood contacts and wets the first and second venting plugs thereby ensuring that any air within the biological fluid collection device is expelled. a housing (13, 20, 22) having a superior surface, an inferior surface, a proximal end, a distal end, an inlet channel, and an outlet channel, wherein a portion of the superior surface of the housing (13, 20, 22) defines a cavity having a cavity superior surface, and wherein a portion of the inferior surface of the housing (13, 20, 22) defines a sacrificial flow channel, the sacrificial flow channel comprising: a middle channel having a first middle channel end, a second middle channel end, and defining a slot, the first middle channel end in fluid communication with the inlet channel, the middle channel extending from the inlet channel in a first direction; a first arcuate channel having a first arcuate channel distal end and a first arcuate channel proximal end, the first arcuate channel distal end in communication with the second middle channel end; and a second arcuate channel having a second arcuate channel distal end and a second arcuate channel proximal end, the second arcuate channel distal end in communication with the second middle channel end; a middle channel having a first middle channel end, a second middle channel end, and defining a slot, the first middle channel end in fluid communication with the inlet channel, the middle channel extending from the inlet channel in a first direction; a first arcuate channel having a first arcuate channel distal end and a first arcuate channel proximal end, the first arcuate channel distal end in communication with the second middle channel end; and a second arcuate channel having a second arcuate channel distal end and a second arcuate channel proximal end, the second arcuate channel distal end in communication with the second middle channel end; a first venting plug disposed in the first arcuate channel proximal end; and a second venting plug disposed in the second arcuate channel proximal end, wherein each of the first arcuate channel and the second arcuate channel are in communication with the inlet channel but are spaced apart from the inlet channel by the middle channel, characterized in that: the first arcuate channel extends from the second middle channel end in a second direction, the second arcuate channel extends from the second middle channel end in the second direction, and the sacrificial flow channel increases the time before blood contacts and wets the first and second venting plugs thereby ensuring that any air within the biological fluid collection device is expelled. the first arcuate channel extends from the second middle channel end in a second direction, the second arcuate channel extends from the second middle channel end in the second direction, and the sacrificial flow channel increases the time before blood contacts and wets the first and second venting plugs thereby ensuring that any air within the biological fluid collection device is expelled.
