| Identifier | Sponsor-defined reference number. | Perm |
| PTTESTCD | Lab Test or Examination Short Name. | Char | (PTTESTCDTESTCDPT) | Topic | Short name of the measurement or test described in PTTEST. It can be used as a column name when converting a dataset from a vertical to a horizontal format. The value in PTTESTCD cannot be longer than 8 characters, nor can it start with a number (e.g., "1TEST" is not valid). PTTESTCD cannot contain characters other than letters, numbers, or underscores. Examples: "NH4", "BENZ". | Req |
| PTTEST | Lab Test or Examination Name | Char | (PTTESTTESTPT) | Synonym Qualifier | Verbatim name of the test or examination used to obtain the measurement or finding. The value in PTTEST cannot be longer than 40 characters. Examples: "Ammonia", "Benzene". | Req |
| PTCAT | Category for Lab Test | Char | (CATPT) | Grouping Qualifier | Used to define a category of related records by purpose. Examples: "HPHC TESTING", "STABILITY STUDY", "DESIGN PARAMETER TESTING". Note: given the vast amount of data types that will use this domain, PTCAT is an expected variable in the PT domain to differentiate and group the records by purpose. | Exp |
| PTSCAT | Subcategory for Lab Test | Char | * | Grouping Qualifier | A further categorization of a test category. Examples: "TEST PRODUCT", "PREDICATE PRODUCT" | Perm |
| PTORRES | Result or Finding in Original Units | Char |
| Result Qualifier | Result of the measurement or finding as originally received or collected. | Exp |

| Variable Qualifier | Lower end of reference range for continuous measurement in original units. Should be populated only for continuous results. | Perm |
| PTORNRHI | Reference Range Upper Limit in Orig Unit | Char |
| Variable Qualifier | Upper end of reference range for continuous measurement in original units. Should be populated only for continuous results. | Perm |
| PTSTRESC | Character Result/Finding in Std Format | Char | (PTSTRESC) | Result Qualifier | Contains the result value for all findings, copied or derived from PTORRES in a standard format or standard units. PTSTRESC should store all results or findings in character format; if results are numeric, they should also be stored in numeric format in PTSTRESN. For example, if a test has results "NONE", "NEG", and "NEGATIVE" in PTORRES and these results effectively have the same meaning, they could be represented in standard format in PTSTRESC as "NEGATIVE". For other examples, see general assumptions. | Exp |
| PTSTRESN | Numeric Result/Finding in Standard Units | Num |
| Result Qualifier | Used for continuous or numeric results or findings in standard format; copied in numeric format from PTSTRESC. PTSTRESN should store all numeric test results or findings. | Exp |
| PTSTRESU | Standard Units | Char | (UNIT) | Variable Qualifier | Standardized unit used for PTSTRESC or PTSTRESN. | ExpPTSTNRLO | Reference Range Lower Limit-Std Units |
| Num | Variable Qualifier | Lower end of reference range for continuous measurements for PTSTRESC/PTSTRESN in standardized units. Should be populated only for continuous results. | Perm | PTSTNRHI | Reference Range Upper Limit-Std Units | Num | Variable Qualifier | Upper end of reference range for continuous measurements in standardized units. Should be populated only for continuous results. | Perm | PTSTNRC | Reference Range for Char Rslt-Std Units | Char |
| Variable Qualifier | For normal range values that are character in ordinal scale or if categorical ranges were supplied (e.g., "-1 to +1", "NEGATIVE TO TRACE"). | Perm |
| PTSTREFC | Reference Result in Standard Format | Char |
| Variable Qualifier | Reference value for the result or finding copied or derived from PTORREF in a standard format. | Perm | PTNRIND | Reference Range Indicator | Char | (NRIND) | Variable Qualifier | Indicates where the value falls with respect to reference range defined by PTORNRLO and PTORNRHI, PTSTNRLO and PTSTNRHI, or by PTSTNRC. Examples: "NORMAL", "ABNORMAL", "HIGH", "LOW".Sponsors should specify in the study metadata (Comments column in the Define-XML document) whether PTNRIND refers to the original or standard reference ranges and results. | Perm |
| PTSTAT | Completion Status | Char | (ND) | Record Qualifier | Used to indicate exam not done. Should be null if a result exists in PTORRES. | Perm |
| PTREASND | Reason Test Not Done | Char |
| Record Qualifier | Describes why a measurement or test was not performed, e.g., "BROKEN EQUIPMENT", or "SAMPLE LOST". Used in conjunction with PTSTAT when value is "NOT DONE". | Perm |
| PTNAM | Vendor Name | Char |
| Record Qualifier | The name or identifier of the laboratory that performed the test. | Perm |
| PTMATRIX | Sample Matrix | Char | (MATRIX) | Record Qualifier | Defines the type of sample used for a measurement. Examples: "TOBACCO", "E-LIQUID", "SMOKE", "VAPOR". | Exp |
| PTMTXCND | Matrix Condition | Char | (MATCOND) | Record Qualifier | Free or standardized text describing the condition of the sample, e.g., "DRY WEIGHT BASIS", "AS-IS". | Perm |

| PTBLFL | Baseline Flag | Char | (NY) | Record Qualifier | Indicator used to identify a baseline value. Should be "Y" or null. Note that PTBLFL is retained for backward compatibility. The authoritative baseline for statistical analysis is in an ADaM dataset. | Perm |
| PTDRVFL | Derived Flag | Char | (NY) | Record Qualifier | Used to indicate a derived record. The value should be "Y" or null. Records that represent the average of other records, or do not come from the CRF, or are not as originally received or collected are examples of records that might be derived for the submission datasets. If PTDRVFL = "Y", then PTORRES may be null, with PTSTRESC and (if numeric) PTSTRESN having the derived value. | Perm |

| PTENDTC | End Date/Time of Sample Collection | Char | ISO 8601 | Timing | End date/time of sample collection represented in ISO 8601 character format. | Perm |
| PTTPT | Planned Time Point Name | Char |
| Timing | - Text description of time when sample should be tested.
