A method, comprising: providing a donor match verification kit, the kit comprising a portable and openable case adapted to house components of the kit at least one reference sample device housed within the case during transport and storage of the casp and removable from the case during use of the device, wherein the reference sample device is adapted for receiving a biological reference specimen from a donor, and at least one biological specimen container housed within the case during transport and storage of the case and removable from the case during use of the container wherein the biological specimen container is adapted for receiving a biological testing specimen from the donor, wherein each of the case the reference sample device and the biological specimen container are pre-marked with the same donor-unique identifier, receiving the reference sample device containing the biological reference specimen collected from the donor; receiving at least a portion of the biological testing specimen collected from the donor; generating a donor-unique biometric marker from the biological reference specimen; and comparing the portion of the biological testing specimen to the donor-unique biometric marker to confirm or reject that the biological reference specimen and the biological testing specimen were collected from the same donor. providing a donor match verification kit, the kit comprising a portable and openable case adapted to house components of the kit at least one reference sample device housed within the case during transport and storage of the casp and removable from the case during use of the device, wherein the reference sample device is adapted for receiving a biological reference specimen from a donor, and at least one biological specimen container housed within the case during transport and storage of the case and removable from the case during use of the container wherein the biological specimen container is adapted for receiving a biological testing specimen from the donor, wherein each of the case the reference sample device and the biological specimen container are pre-marked with the same donor-unique identifier, a portable and openable case adapted to house components of the kit at least one reference sample device housed within the case during transport and storage of the casp and removable from the case during use of the device, wherein the reference sample device is adapted for receiving a biological reference specimen from a donor, and at least one biological specimen container housed within the case during transport and storage of the case and removable from the case during use of the container wherein the biological specimen container is adapted for receiving a biological testing specimen from the donor, wherein each of the case the reference sample device and the biological specimen container are pre-marked with the same donor-unique identifier, receiving the reference sample device containing the biological reference specimen collected from the donor; receiving at least a portion of the biological testing specimen collected from the donor; generating a donor-unique biometric marker from the biological reference specimen; and comparing the portion of the biological testing specimen to the donor-unique biometric marker to confirm or reject that the biological reference specimen and the biological testing specimen were collected from the same donor.
