|---|---|
| Department | Biochemistry |
| Test Code | DIG |
| Synonyms | Digitalis |
| Test Availability | Monday - Sunday, testing routinely available out of hours |
| Turnaround Time | 1 – 5hrs |
| Stability – Add test | 8 hours |
Specimen Requirements | |
| Specimen Type | Serum
Plasma |
| Specimen Transportation | |
| Preferred | 6 mL Red-Top |
| Acceptable | 6 mL Li-Hep Green-Top |
| Unacceptable | |
| Paediatric Requirements | Li-Heparin Microtainer |
Aliquot Requirements | |
| Sample Type | Serum
Plasma |
| Preferred Volume | 500 µL |
| Minimum Volume | 200 µL |
| Aliquot Transportation | |
Clinical Information | |
| Reference Intervals | Range 0.6 - 2.0 nmol/L
Toxic levels >2.0 nmol/L |
| Test Method | Abbott Alinity Ci, Particle-enhanced turbidimetric inhibition immunoassay (PETINIA) |
| Advanced Notice | Not required |
| Patient Preparation | Samples are best taken at the trough, just before the next dose, or at least 8-12 hours post-dose, to avoid falsely high results due to delayed drug distribution after the dose. |
Comments | |
| Specimens from patients treated with Digoxin immune FAB (Digibind) should be viewed with caution, as this substance is known to inhibit the assay.
Heterophilic antibodies have been shown to interact with immunoglobulin reagents in some immunoassay systems. | |
