Abstract
The invention relates to a new dipstick assay for detecting and quantifying the content of an target analyte in a sample. The assay is particularly useful for example in the diagnosis and monitoring of alcoholism by the detection of asialo transferrin or carbohydrate free transferrin (CFT). Thus, provided is a dipstick for determining the content of a target analyte variant in a mixture of analyte variants in a sample, comprising: a) a sample application zone, b) a screening zone having an immobilised binding ligand having a binding affinity for a non-target analyte variant or varinats, c) a conjugate zone comprising a detector reagent, d) a reading zone for detection of said analyte.
