12.2 Examples of applying the business rules for users mapping their local panels to LOINC panels
12.2.1 Comparison Panel: Varicella zoster virus IgG and IgM panel – Serum (LOINC: 45063-5)
This user-defined panel is considered comparable since the component tests are the same and it is acceptable to use method-specific LOINC codes for panels defined with methodless LOINC codes.
Elements of LOINC Panel
| LOINC_NUM | Long Common Name | R/O/C |
|---|---|---|
| 8048-1 | Varicella zoster virus IgM Ab [Units/volume] in Serum | R |
| 8047-3 | Varicella zoster virus IgG Ab [Units/volume] in Serum | R |
Elements of User-defined Panel
| LOINC_NUM | Long Common Name |
|---|---|
| 5404-9 | Varicella zoster virus IgM Ab [Units/volume] in Serum by Immunoassay |
| 5403-1 | Varicella zoster virus IgG Ab [Units/volume] in Serum by Immunoassay |
12.2.2 Comparison Panel: Creatine kinase panel – Serum or Plasma (LOINC: 24335-2)
This user-defined panel is not considered to be comparable since it includes two additional measured components that are not in the LOINC Panel.
Note
The inclusion of an Optional component in the LOINC Panel does not have a bearing on the comparability of the user-defined panel.
Elements of LOINC Panel
| LOINC_NUM | Long Common Name | R/O/C |
|---|---|---|
| 2157-6 | Creatine kinase [Enzymatic activity/volume] in Serum or Plasma | R |
| 20569-0 | Creatine kinase.MB/Creatine kinase.total in Serum or Plasma | R |
| 9642-0 | Creatine kinase.BB/Creatine kinase.total in Serum or Plasma | R |
| 9643-8 | Creatine kinase.MM/Creatine kinase.total in Serum or Plasma | R |
| 5912-1 | Creatine kinase isoenzymes [interpretation] in Serum or Plasma | O |
Elements of User-defined Panel
| LOINC_NUM | Elements of User-defined Panel |
|---|---|
| 2157-6 | Creatine kinase [Enzymatic activity/volume] in Serum or Plasma |
| 20569-0 | Creatine kinase.MB/Creatine kinase.total in Serum or Plasma |
| 9642-0 | Creatine kinase.BB/Creatine kinase.total in Serum or Plasma |
| 9643-8 | Creatine kinase.MM/Creatine kinase.total in Serum or Plasma |
| 26020-8 | Creatine Kinase.macromolecular type 2/Creatine kinase.total in Serum or Plasma |
| 26019-0 | Creatine Kinase.macromolecular type 1/Creatine kinase.total in Serum or Plasma |
12.2.3 Comparison Panel: Drugs of abuse 5 panel – Urine by Screen method (LOINC: 65750-2)
This user-defined panel is considered to be comparable since the components use the same method-specific LOINC terms and the additional test is a non-measured component (i.e., it is a variable provided by the requester that is echoed back with the results).
Elements of LOINC Panel
| LOINC_NUM | Long Common Name | R/O/C |
|---|---|---|
| 19261-7 | Amphetamines [Presence] in Urine by Screen method | R |
| 14314-9 | Benzoylecgonine [Presence] in Urine by Screen method | R |
| 18282-4 | Cannabinoids [Presence] in Urine by Screen method | R |
| 19295-5 | Opiates [Presence] in Urine by Screen method | R |
| 19659-2 | Phencyclidine [Presence] in Urine by Screen method | R |
Elements of User-defined Panel
| LOINC_NUM | Long Common Name |
|---|---|
| 19261-7 | Amphetamines [Presence] in Urine by Screen method |
| 14314-9 | Benzoylecgonine [Presence] in Urine by Screen method |
| 18282-4 | Cannabinoids [Presence] in Urine by Screen method |
| 19295-5 | Opiates [Presence] in Urine by Screen method |
