Abstract

An apparatus and method for collecting a breath sample are provided. The apparatus includes a breath input interface configured to receive exhaled breath, a metering device configured to determine a constituent level in the breath being received, a first conduit system extending from the breath input interface and connected to at least one breath sample storage device, a valve positioned along the first conduit system to control a flow of the exhaled breath towards the at least one breath sample storage device, and at least one controller configured to determine if the constituent level is within a constituent level target range, if a change rate in the constituent level is within a constituent level change rate target range, and control the valve to open at least partially based on these conditions.
