Abstract: In accordance with some embodiments, systems, methods, and media for determining relative quality of oligonucleotide preparations. In some embodiments, a system comprises a processor programmed to: (a) receive genetic sequencing results for multiple libraries with target concentrations of oligonucleotides; (b) calculate at least one prediction band; (c) repeat (a) and (b) for multiple preparations; (d) determine boundaries for a final prediction band based on the prediction bands calculated at (b) for each of the preparations; and (e) present a report indicative of quality of the libraries, including metrics indicative of the final prediction band.

Abstract: The disclosure provides compositions and methods for the quantification of a target nucleic acid sequence or sequences in a sample using next generation sequencing. The methods of the disclosure can be used to determine titer of one or more target organisms in a sample.
