1. A method, comprising:
(a) providing a sample obtained from a subject comprising a first target molecule and a second target molecule;
(b) attaching to each of a plurality of occurrences of the first target molecule and the second target molecule in the sample a label sequence randomly selected from a set of diverse label sequences, wherein the set comprises labels with m different label sequences, thereby generating for each occurrence of the first target molecule and the second target molecule a new first molecule and a new second molecule, respectively,
wherein each new first molecule and new second molecule comprises a copy of the first target molecule and a copy of the second target molecule, respectively, and a label,
wherein n1 and n2 are the numbers of the one or more occurrences of the first target molecule and the second target molecule, respectively, in the sample, and
wherein the ratio of the greater of n1 and n2 is smaller than 0.2; and
(c) detecting the new first molecules and the new second molecules by detecting the label sequences present on the new first molecules and the new second molecules, wherein the numbers of the new first molecules and the new second molecules detected indicate the numbers of the one or more occurrences of the first molecule and the second molecule, respectively, in the sample.
