Abstract

Laboratory testing plays a significant and growing role in the delivery of medical services. Fresh analysis of past test results has led to discovery of previously unknown correlations between statistical properties of analyte values and parameters such as age, sex, and region. Observed values in patient populations have also newly been discovered to show both secular and regular periodic variations over time. Embodiments of the invention may use information about these correlations to improve delivery of medical care.

Claims

1. A computer system for calculating a reference range, the computer system comprising:

one or more processors; and

one or more computer-readable storage media encoded with instructions that, when executed by at least one of the processors, cause the computer system at least to

correlate with at least one time-periodic function a plurality of results of the medical test performed at a plurality of times upon a plurality of members of a population; and

calculate a reference range based at least on the time-periodic function.

2. A computer system for providing a medical test result, the computer system comprising:

one or more processors;

one or more hardware interfaces;

one or more databases; and

one or more computer-readable storage media encoded with instructions that, when executed by at least one of the processors, cause the computer system at least to

receive through at least one of the hardware interfaces a medical test result that comprises a value for an analyte;

retrieve from at least one of the databases a reference range for the analyte, the reference range being based at least on a time-periodic function; and

transmitting through at least one of the hardware interfaces a report that comprises the medical test result and the reference range.

3. A computer system for calculating a real age for a patient, the computer system comprising:

one or more processors;

one or more hardware interfaces;

one or more databases; and

one or more computer-readable storage media encoded with instructions that, when executed by at least one of the processors, cause the computer system at least to

receive through an interface coupled to at least one of the processors a plurality of values, each respective value representing a result of a test within at least one longitudinal series of tests on the patient over a period of time;

correlate one or more of the longitudinal series of results with one or more respective time-periodic functions, stored in the database, that are known to correlate with results of the medical test in a population in a way that depends on the ages of members of the population;

calculate a real age of the patient based at least on the degree to which one or more of the longitudinal series of results was correlated with one or more of the time-periodic functions; and

provide output through at least one of the interfaces indicating the calculated real age of the patient.

4. A computer system for calculating a dose of a drug, the computer system comprising:

one or more processors;

one or more hardware interfaces;

one or more databases; and

one or more computer-readable storage media encoded with instructions that, when executed by at least one of the processors, cause the computer system at least to

receive through at one or more interfaces coupled to at least one of the processors a result of a laboratory test and a time at which the test was performed;

select a reference range for the laboratory test, the reference range having been calculated based on a time periodic function and the selection being based on the time at which the test was performed;

compare the result with the reference range; and

calculate the dose of the drug based on the comparison between the result and the reference range.

5. A computer system for providing prescription drug benefits, the computer system comprising:

one or more processors;

one or more databases; and

one or more computer-readable storage media encoded with instructions that, when executed by at least one of the processors, cause the computer system at least to

retrieve from at least one of the databases a reference range for the analyte, the reference range being based at least on a time-periodic function;

identify a drug that may be prescribed for a patient in response to an detected abnormal value for the analyte in the patient; and

based on the calculated reference range, calculate a prescription drug benefit that is to be provided for a patient who is prescribed the drug.

6. A computer system for providing medical testing services, the computer system comprising:

one or more processors;

one or more hardware interfaces;

one or more databases; and

one or more computer-readable storage media encoded with instructions that, when executed by at least one of the processors, cause the computer system at least to

receive through at least one of the interfaces a requisition for a test that is to be performed at least two times on a patient, the test comprising obtaining a value for an analyte;

retrieve from at least one of the databases a reference range for the analyte, the reference range being based at least on a time-periodic function;

identify respective occasions for performing the test on the patient based on the reference range, such that the time-periodicity of the function indicates that the tests on the patient may be expected to yield substantially different values.
