Optimized specimen collection for laboratory tests

Abstract

Embodiments of the invention relate to methods of optimizing the collection of specimens, e.g., of blood, when multiple laboratory tests have been prescribed at one time for a patient. Laboratory tests may use specimens such as blood, drawn, e.g., through venipuncture, and patients may experience greater discomfort, inconvenience, and/or anxiety as more and more blood is collected, and at greater expense. Embodiments of the invention include computer systems configured to optimize the collection of specimens for laboratory tests to reduce the number of specimens that must be collected from a patient for any given set of laboratory tests.

 receiving through one of the interfaces a requisition for the laboratory tests, each of the tests being associated with respective collection requirements including a required number of containers;   for each of the requisitioned tests, retrieving the associated collection requirements from at least one of the computer-readable storage media;   at least one of the processors executing instructions to compute the total number of containers to be collected;   at least one of the processors executing instructions to determine that the number exceeds a collection limit; and   at least one of the processors executing instructions to apply one or more optimizations until the collection cannot be further optimized or the optimized number of containers no longer exceeds the collection limit.
