Abstract

Systems, methods, and computer program products for determining relative normalcy and abnormalcy of a plurality of test results are provided. Test results are transformed into respective unitized values and then graphically displayed with a unitized reference range. A unitized analytical variation of each of the respective unitized values may be determined and displayed. Unitized data can be graphically presented in a predefined order to produce patterns. These patterns can be compared, either manually or electronically, with other patterns representative of known conditions to quickly and easily assess the medical status of multiple body organs and/or systems of a patient, or to assess the condition of various attributes of objects including any type of process, product, machine, or system capable of being measured.
