Interference of Asian, American, And Indian (Ashwagandha) Ginsengs in Serum Digoxin Measurements by a Fluorescence Polarization Immunoassay Can Be Minimized by Using a New Enzyme-Linked Chemiluminescent Immunosorbent Or Turbidimetric Assay (Clinical Report‪)‬

* Context.--Ginsengs are widely used by the general population. These herbs interfere with serum digoxin measurement using the fluorescence polarization immunoassay. Objective.--To assess potential interference of different ginsengs (Asian, American, and Indian, also known as Ashwagandha) in vitro and in vivo in a mouse model by using a new enzyme-linked chemiluminescent immunosorbent digoxin assay and an existing turbidimetric assay. Comparisons were made with the fluorescence polarization immunoassay.
