Abstract: Compositions and methods for detecting a non-specific nucleic acid amplification inhibitor in a reaction are disclosed. An internal positive control (IPC) may be included in samples to be tested for target nucleic acids as a means to monitor non-specific inhibition of nucleic acid amplification and provide confidence in negative results obtained in target-specific assays. Provided herein are an IPC polynucleotide, IPC control primers, and IPC probes. Also provided are methods of using an IPC polynucleotide, primers, and probes to detect a non-specific nucleic acid amplification inhibitor.

Abstract: The present invention provides methods and compositions for determining the presence and/or amount of HBV nucleic acids in a test sample. In particular, substantially purified oligonucleotide primers and probes are described that can be used for qualitatively and quantitatively detecting HBV nucleic acid in a test sample by amplification methods. The present invention also provides primers and probes for generating and detecting control nucleic acid sequences that provide a convenient method for assessing internal quality control of the HBV assay.

Abstract: Provided are methods for reducing transfer of fluid between liquid samples subject to consecutive instrument controlled filter sampling. Transfer of fluid between subsequent samples is reduced by decontaminating surfaces of the instrument. The methods reduce sample contamination so that any remaining unused sample may be subject to diagnostic analysis without less concern that the outcome will be the result of sample cross-contamination.
