MIRESCAT Result Category Char Variable Qualifier Used to categorize the result of a finding. Examples: "MALIGNANT" or "BENIGN" for tumor findings. Perm
MISTAT Completion Status Char Record Qualifier Used to indicate examination not done or result is missing. Should be null if a result exists in MIORRES or have a value of "NOT DONE" when MIORRES is null. Perm
MIREASND Reason Not Done Char Record Qualifier Reason not done. Used in conjunction with MISTAT when value is NOT DONE. Examples: "SAMPLE AUTOLYZED", "SPECIMEN LOST". Perm
MINAM Laboratory/Vendor Name Char Record Qualifier Name or identifier of the vendor (e.g., laboratory) that provided the test results. Perm
MISPEC Specimen Material Type Char Record Qualifier Subject of the observation. Defines the type of specimen used for a measurement. Examples: "TISSUE", "BLOOD", "BONE MARROW". Req
MISPCCND Specimen Condition Char Record Qualifier Free or standardized text describing the condition of the specimen. Example: "AUTOLYZED". Exp

MILAT Specimen Laterality within Subject Char Variable Qualifier Qualifier for laterality of the location of the specimen in MILOC. Examples: "LEFT", "RIGHT", "BILATERAL". Perm
MIDIR Specimen Directionality within Subject Char Variable Qualifier Qualifier for directionality of the location of the specimen in MILOC. Examples: "DORSAL", "PROXIMAL". Perm
MIMETHOD Method of Test or Examination Char Record Qualifier Method of the test or examination. This could include the technique or type of staining used for the slides. Examples: "IHC", "Crystal Violet", "Safranin", "Trypan Blue", or "Propidium Iodide". Perm
MILOBXFL Last Observation Before Exposure Flag Char Record Qualifier Operationally-derived indicator used to identify the last non-missing value prior to RFXSTDTC. The value should be "Y" or null. Perm
MIBLFL Baseline Flag Char Record Qualifier Indicator used to identify a baseline value. The value should be "Y" or null. Note that MIBLFL is retained for backward compatibility. The Exp
        authoritative baseline flag for statistical analysis is in an ADaM dataset.  
MIEVAL Evaluator Char Record Qualifier Role of the person who provided the evaluation. Example: "PATHOLOGIST", "PEER REVIEW", "SPONSOR PATHOLOGIST". Perm
