Test Limitations

Endogenous substances such as DLIF (digoxin-like immunoreactive factors) may interfere with this assay by yielding slightly elevated results.
 

The manufacturer of Digoxin Immune FAb (Antibody fragment therapy) has stated that no immunoassay technique is suitable for quantitating digoxin in serum from patients undergoing this treatment.
 

Falsely elevated digoxin values are obtained in patients undergoing digitoxin therapy. Samples from patients using Uzara for treatment of diarrhea may cause falsely elevated digoxin results.
