Decision support system and method for diagnosis consultation in laboratory hematopathology
First Claim
1. A method of interpreting hematopathology test results to arrive at a diagnosis of a patient comprising the steps of:
- conducting at least one hematopathology test on at least one sample from a patient;
retrieving data from said at least one hematopathology test for the patient and storing said hematopathology test data in a database;
comparing said hematopathology test data with at least one set of a predetermined number of hematopathology patterns, each of said hematopathology patterns corresponding to different patient conditions and said patterns arranged in a predetermined hierarchy, to determine which patterns match said hematopathology test data in said database;
displaying the patterns matched, with recommendations corresponding to the matched patterns for one of no additional testing and one of a plurality of identified additional testing, the results of which are likely to lead to a diagnosis of the patient'"'"'s condition;
conducting any additional testing recommended, retrieving the data therefrom and storing it in said database with said hematopathology test data;
comparing said additional test data and hematopathology test data with said predetermined number of patterns, to determine which patterns match said hematopathology test data in said database; and
identifying and displaying the highest ranked pattern in said hierarchy to arrive at a differential diagnosis of the patient'"'"'s condition.

Abstract
A system and method of diagnosis provides that data from a hematopathology analyzer, e.g., hematology analyzer and/or other blood testing instrument or test, is input and compared with patterns corresponding to specific patient conditions. The matched patterns are arranged in a hierarchy in accordance with predetermined rules. Initially the patterns matched are displayed, optionally with recommendations for additional testing. If additional testing is done, a comparison of the original test data and new data is done, the patterns matched and at least one highest ranked pattern is identified, optionally with a differential diagnosis.

7. A method of interpreting hematopathology test results to arrive at a diagnosis of a patient;
- comprising the steps of;
conducting at least one hematopathology test on at least one sample from a patient, said hematopathology test being a flow cytometry test; retrieving data from said flow cytometry test for the patient and storing said flow cytometry test data in a database; comparing said flow cytometry test data with at least one set of a predetermined number of hematopathology patterns previously stored in said database, each of said hematopathology patterns corresponding to different patient conditions and said patterns arranged in a predetermined hierarchy to determine which patterns match said flow cytometry test data in said database; and identifying and displaying at least one highest ranked pattern in said hierarchy to arrive at a differential diagnosis of the patient'"'"'s condition. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system for interpreting hematopathology test results to arrive at a diagnosis of a patient, comprising:
-
database storage means for storing a database of test results from hematopathology tests for specific patients; knowledge base/inference engine means for storing at least one set of a predetermined number of patterns corresponding to specific patient conditions, including a normal condition, with said patterns arranged in a predetermined hierarchy, and for storing instructions for comparing said patterns to said database of test results for determining which patterns are matched; comparing means for comparing data from said tests for a specific patient with said patterns to determine which patterns are matched and which pattern is highest in the hierarchy; input means for inputting said data from test results into said database; and output means for outputting the results of said comparison by said comparing means, said results being comprised of at least one of the highest ranked pattern, a differential diagnosis and recommendations for additional testing. - View Dependent Claims (14, 15, 16, 17, 18)
