A system comprising: a) a sample transport container, the sample transport container adapted to store and enable transport of a plurality of sample holders for samples of biological materials collected from patients; b) a set of one or more environment sensors adapted to take measurements of one or more characteristics of an environment of the sample transport container; c) a sample manager located at a testing location and programmed to, for each sample of biological material transported in the sample transport container, make history logging information for that sample of biological material available at the testing location, wherein the history logging information is taken from a set of history logs, each of which: i) is associated with a single sample of biological material with a unique identifier for that sample of biological material; and ii) comprises: A) a set of measurements of one or more characteristics of the environment of the sample transport container while the associated sample of biological material was in transit; and B) a transit initiation timestamp, wherein the transit initiation timestamp is when the associated sample of biological material was placed into the sample transport container for transit; d) a set of one or more history loggers, wherein each history logger from the set of history loggers is a smartphone configured with a first program; and e) a central monitor configured to determine, for each history logger from the set of history loggers, a distance between the history logger and the sample manager using a GPS receiver incorporated into the history logger; wherein A) the sample manager is a computer configured with a second program; B) the central monitor is a server configured with a third program; and C) each history logger from the set of history loggers is programmed to receive, for inclusion in the history logs of samples of biological material handled by users of the history loggers, transit data for those samples of biological material. a) a sample transport container, the sample transport container adapted to store and enable transport of a plurality of sample holders for samples of biological materials collected from patients; b) a set of one or more environment sensors adapted to take measurements of one or more characteristics of an environment of the sample transport container; c) a sample manager located at a testing location and programmed to, for each sample of biological material transported in the sample transport container, make history logging information for that sample of biological material available at the testing location, wherein the history logging information is taken from a set of history logs, each of which: i) is associated with a single sample of biological material with a unique identifier for that sample of biological material; and ii) comprises: A) a set of measurements of one or more characteristics of the environment of the sample transport container while the associated sample of biological material was in transit; and B) a transit initiation timestamp, wherein the transit initiation timestamp is when the associated sample of biological material was placed into the sample transport container for transit; i) is associated with a single sample of biological material with a unique identifier for that sample of biological material; and ii) comprises: A) a set of measurements of one or more characteristics of the environment of the sample transport container while the associated sample of biological material was in transit; and B) a transit initiation timestamp, wherein the transit initiation timestamp is when the associated sample of biological material was placed into the sample transport container for transit; A) a set of measurements of one or more characteristics of the environment of the sample transport container while the associated sample of biological material was in transit; and B) a transit initiation timestamp, wherein the transit initiation timestamp is when the associated sample of biological material was placed into the sample transport container for transit; d) a set of one or more history loggers, wherein each history logger from the set of history loggers is a smartphone configured with a first program; and e) a central monitor configured to determine, for each history logger from the set of history loggers, a distance between the history logger and the sample manager using a GPS receiver incorporated into the history logger; wherein A) the sample manager is a computer configured with a second program; B) the central monitor is a server configured with a third program; and C) each history logger from the set of history loggers is programmed to receive, for inclusion in the history logs of samples of biological material handled by users of the history loggers, transit data for those samples of biological material.
