1. A method for genotyping a target nucleic acid in a sample is provided comprising:
- (a) generating a first detection mixture by a method comprising contacting a portion of the sample with a first probe set, wherein the first probe set comprises a nucleic acid probe specific for a first genotype of the target nucleic acid and a nucleic acid probe specific for a second genotype of the target nucleic acid, but does not comprise a nucleic acid probe specific for a third genotype of the target nucleic acid;
(b) generating a second detection mixture by a method comprising contacting a portion of the sample with a second probe set, wherein the second probe set comprises a nucleic acid probe specific for the second genotype of the target nucleic acid and a nucleic acid probe specific for the third genotype of the target nucleic acid, but does not comprise a nucleic acid probe specific for the first genotype of the target nucleic acid; and
(c) treating the first and second detection mixtures under conditions wherein the nucleic acid probes hybridize specifically to the first, second, and/or third genotype of the target nucleic acid; and
(d) detecting hybridization of the nucleic acid probe to the target nucleic acid, wherein;
(i) hybridization in the first detection mixture, but not the second detection mixture indicates that the sample comprises the first genotype of the target nucleic acid;
(ii) hybridization in the second detection mixture, but not the first detection mixture, indicates that the sample comprises the third genotype of the target nucleic acid; and
(iii) hybridization in the first detection mixture and the second detection mixture indicates that the sample comprises the second genotype of the target nucleic acid.

Abstract
Methods are provided for genotyping a target nucleic acid in a sample. In various aspects, the methods comprise generating nucleic acid hybrids between probes specific for the genotypes of interest and the target nucleic acid and detecting hybridization in the sample. In other aspects, the methods comprise using multi-probe mixtures to reduce the volume of sample necessary to determine the genotype of the target nucleic acid.
