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.
