The present invention provides polynucleotides that can specifically hybridise to Hepatitis B virus (HBV) nucleic acids from all genotypes. These polynucleotides can be used in genotype-independent detection and quantitation of HBV nucleic acids. For example, the polynucleotides can be used as primers and/or probes in amplification-based assays for either end-point detection or real-time monitoring of HBV nucleic acids in a test sample. The polynucleotides can additionally be provided as part of a kit for the detection and quantitation of HBV nucleic acids.

The invention relates to multiplex ligase chain reaction (LCR). Two or more putative target sequences are selected. For each one, a set of four probes is used simultaneously to amplify the putative sequence if it is present in the sample. Preferably, all the amplicons are labeled with a common label/hapten and, for each different target, with a unique label/hapten. The invention also relates to an immunochromatographic strip device and method employing a diagonal array of capture spots.
