PCSTRESC should store all results or findings in character format; if results are numeric, they should also be stored in numeric format in PCSTRESN. For example, if a test has results "NONE", "NEG", and "NEGATIVE" in PCORRES, and these results effectively have the same meaning, they could be represented in standard format in PCSTRESC as "NEGATIVE". For other examples, see general assumptions. | Exp |

| Record Qualifier | Describes why a result was not obtained, such as "SPECIMEN LOST". Used in conjunction with PCSTAT when value is "NOT DONE". | Perm |
| PCNAM | Vendor Name | Char |
| Record Qualifier | Name or identifier of the laboratory or vendor who provides the test results. | Exp |

| PCLLOQ | Lower Limit of Quantitation | Num |
| Variable Qualifier | Indicates the lower limit of quantitation for an assay. Units should be those used in PCSTRESU. | Exp |
| PCULOQ | Upper Limit of Quantitation | Num |
| Variable Qualifier | Indicates the upper limit of quantitation for an assay. Units should be those used in PCSTRESU. | Perm |
| VISITNUM | Visit Number | Num |
