| VSSTRESC | Character Result/Finding in Std Format | Char |
| Result Qualifier | Contains the result value for all findings, copied or derived from VSORRES in a standard format or standard units. VSSTRESC should store all results or findings in character format; if results are numeric, they should also be stored in numeric format in VSSTRESN. For example, if a test has results "NONE", "NEG", and "NEGATIVE" in VSORRES, and these results effectively have the same meaning, they could be represented in standard format in VSSTRESC as "NEGATIVE". | Exp |
| VSSTRESN | 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 VSSTRESC. VSSTRESN should store all numeric test results or findings. | Exp |
| VSSTRESU | Standard Units | Char | (VSRESU) | Variable Qualifier | Standardized unit used for VSSTRESC and VSSTRESN. | Exp |
| VSSTAT | Completion Status | Char | (ND) | Record Qualifier | Used to indicate that a vital sign measurement was not done. Should be null if a result exists in VSORRES. | Perm |
| VSREASND | Reason Not Performed | Char |
| Record Qualifier | Describes why a measurement or test was not performed. Examples: "BROKEN EQUIPMENT", "SUBJECT REFUSED". Used in conjunction with VSSTAT when value is "NOT DONE". | Perm |
| VSLOC | Location of Vital Signs Measurement | Char | (LOC) | Record Qualifier | Location relevant to the collection of vital signs measurement. Example: "ARM" for blood pressure. | Perm |

| VSTOX | Toxicity | Char |
| Variable Qualifier | Description of toxicity quantified by VSTOXGR. | Perm |
| VSTOXGR | Standard Toxicity Grade | Char |
| Record Qualifier | Records toxicity grade value using a standard toxicity scale (e.g., NCI CTCAE). If value is from a numeric scale, represent only the number (e.g., "2", not "Grade 2"). | Perm |
| Clinically Significant, Collected | Char | (NY) | Record Qualifier | Used to indicate whether a collected observation is clinically significant based on judgment. | Perm |
| VISITNUM | Visit Number | Num |
| Timing | - An assigned numeric identifier that aligns to the chronological order of an encounter.
- Numeric version of VISIT, used for sorting.
| Exp |
| VISIT | Visit Name | Char |

description of clinical - encounter.
- May be used in addition to VISITNUM and/or VISITDY.
| Perm |

| Timing | Numerical version of VSTPT to aid in sorting. | Perm |
| VSELTM | Planned Elapsed Time from Time Point Ref | Char | ISO 8601 duration | Timing | Planned elapsed time (in ISO 8601) relative to a planned fixed reference (VSTPTREF). This variable is useful where there are repetitive measures. Not a clock time or a date time variable. Represented as an ISO 8601 Duration. Examples: "-PT15M" to represent the period of 15 minutes prior to the reference point indicated by VSTPTREF, "PT8H" to represent the period of 8 hours after the reference point indicated by VSTPTREF. | Perm |
