GTTESTCD

Lab Test or Examination Short Name

Char

(GTTESTCD)

Topic

Short name of the measurement, test, or examination described in GTTEST. It can be used as a column name when converting a dataset from a vertical to a horizontal format. The value in GVTESTCD cannot be longer than 8 characters, nor can it start with a number (e.g., “1TEST” is not valid). GVTESTCD cannot contain characters other than letters, numbers, or underscores. Examples: RVERT, CYTOTOX.

Req

GTTEST

Lab Test or Examination Name

Char

(GTTEST)

Synonym Qualifier

Long name for GTTESTCD. The value in GTTEST cannot be longer than 40 characters. Examples: Revertants, Cytotoxicity.

Req

GTORRES

Result or Findings as Collected

Char

 

Result Qualifier

Result of the measurement or finding as originally received or collected.

Exp

GTORRESU

Unit of the Original Result

Char

(UNIT)

Variable Qualifier

The unit for the original result. The unit of the original result should be mapped to a synonymous unit on the Controlled Terminology list.

Exp

GTCELLEV

Number of Cells Evaluated

Num


Result Qualifier

The number of cells evaluated.

Perm

GTCOLSRT

Collected Summary Result Type

Char

(COLSTYP)

Variable Qualifier

Used to indicate the type of collected summary result. For example, MAXIMUM, MINIMUM, and MEAN

Perm

GTSTRESC

Standardized Result in Character Format

Char

New code list needed

 e

Result Qualifier

Contains the result value for all findings, copied or derived from GTORRES in a standard format or standard units. GTSTRESC should store all results or findings in character format; if results are numeric, they should also be stored in numeric format in GTSTRESN. For example, if a test has results NONE, NEG, and NEGATIVE in GTORRES and these results effectively have the same meaning, they could be represented in standard format in GTSTRESC as NEGATIVE. For other examples, see general assumptions.

Exp

GTSTRESN

Standardized Result in Numeric Format

Num

 

Result Qualifier

Used for numeric results or findings in standard format; contains the numeric form of GTSTRESC. GTSTRESN should store all numeric test results or findings.

Exp

GTSTRESU

Unit of the Standardized Result

Char

(UNIT)

Variable Qualifier

Standardized unit used for GTSTRESC, GTSTRESN, GTSTRLO, and GTSTRHI.

Exp

GTRUNID

Run ID

Char


Record Qualifier

A sequence of characters used to uniquely identify a particular run of a test on a particular batch of samples.

Perm

GTSTAT

Completion Status

Char

(ND)

Record Qualifier

Used to indicate when a test is not done or result is missing. Should be null if a result exists in GTORRES.

Perm

GTREASND

Reason Not Done

Char

 

Record Qualifier

Describes why GTSTAT is NOT DONE, such as BROKEN EQUIPMENT or SPECIMEN LOST.

Perm

GTSPCCND

Specimen Condition

Char

?

Record Qualifier

Free or standardized text describing the condition of the specimen. Example: PRECIPITATION PRESENT, CONTAMINATION PRESENT, etc.  If multiple conditions are present on a sample, concatenate the values with a semicolon and no spaces as a separator

Perm

GTSPCUFL

Specimen Usability for the Test

Char

(NY)

Record Qualifier

Describes the usability of the specimen for the test. Should be N if the specimen is not usable; otherwise it should be null.

Perm

GTMETHOD

Method of Test or Examination

Char


Record Qualifier

Method of the test or examination. Examples: MANUALLY COUNTED, INSTRUMENT COUNTED

Exp

GTEXCLFL

Exclusion Flag

Char

(NY)

Record Qualifier

Y if the result should be excluded from all calculations, otherwise null.

Perm

GTREASEX

Reason for Exclusion

Char

 

Record Qualifier

The reason the result should be excluded from all calculations. Used only when GTEXCLFL is Y.

6.3.?.1  ASSUMPTIONS FOR In-Vitro TEST RESULTS (GT) DOMAIN MODEL

  1. GT Definition: This domain captures in vitro data collected by the lab executing the study or received from a provider.  This domain is designed for exchanging sample (entity) level data for the following in vitro tests: Neutral Red Cytotoxity Assay, Bacterial Reverse Mutation Assay, Mammalian Cell Gene Mutation Assay, and Micronucleus Assay.  Other in vitro tests have not yet been modeled in this version of this domain.

  2. Entity Identifier:
    1. ENID is unique within the assay (and a study can have many assays)
    2. Replicates vs. Run 
      • need planned (ei.xpt) separate from the actual (gt.xpt)
      • If tests run at the same time, they are replicates and are assigned the same RUNID
      • If tests are run at separate times, they are runs and the RUNIDs are distinct
    3. Different runs would be expected to have different ENID and GTDTC values. In ei.xpt, these are distinguished by different RUNID values.
    4. Entities that are replicates of each other would be expected to
      • have different ENID values
      • be in the same trial set (SETCD values)
      • have the same RUNID values
  3. Results Definition:
    1. GTSTRESC and the corresponding numeric GTSTRESN should generally be used to represent standardized format of original results.
    2. GTSTAT and GTREASND are Permissible and used to indicate when a test was not completed. In these cases GTSTAT should contain “NOT DONE”; GTORRES, GTSTRESC, and GTSTRESN should be null; and GTREASND should contain the reason for not completing the test.
  4. Other Assumptions:
    1. The discussion in Section 4.5.1.3 concerning TESTS NOT DONE does not apply to this domain.
    2. GTEXCLFL and GTREASEX are Permissible and used to indicate when a test is to be excluded from further analysis. In these cases GTREASEX should contain the reason for exclusion.
