Abstract
A system for verifying a sample volume includes a sample reservoir and a volumetric verification device. The sample reservoir defines an inner volume and is configured to receive a volume of bodily fluid. The inner volume of the sample reservoir contains an additive. The volumetric verification device includes a first indicator and a second indicator. The volumetric verification device is configured to selectively engage the sample reservoir to (1) place the first indicator in a first position along a length of the sample reservoir such that the first indicator is substantially aligned with a surface and/or meniscus of the additive and (2) place the second indicator in a second position along the length of the sample reservoir such that the second indicator is substantially aligned with a predetermined fill volume when bodily fluid is transferred to the inner volume.
