| # RefLab |
|
|
| Reference-interval lookup built from Appendix A of the Tietz Textbook of Clinical Chemistry and |
| Molecular Diagnostics, 7th edition (Tables A.1–A.5), with Ricos biological-variation |
| specifications attached where they exist. |
|
|
| - **RefCheck** — analyte, age, sex and a result in either unit; verdict, interval in both units, |
| conversion factor, critical-value flag. |
| - **RefSurf** — every partition an analyte has, as tables, range bars and interval-versus-age plots. |
| - **Critical** — Table A.5 risk thresholds. |
|
|
| 429 entries · 2447 partitions · 64 critical values · 114 analytes with biological-variation data. |
|
|
| Everything runs client-side in a single `index.html`; no server, no network calls. |
|
|
| Reference intervals are method- and population-dependent. Each laboratory establishes or verifies |
| its own intervals (CLSI EP28-A3c) before clinical use. Not a diagnostic device. |
