Patent ID: 8775092

Claim:
A method of identifying biological material in a sample, comprising: extracting one or more nucleic acid molecule(s) from a sample comprising a biological material, said sample being a subject sample including a subject's DNA as well as DNA of any organisms in the subject or an environmental sample including organisms in their natural state in the environment; generating a plurality of short strings of nucleotide sequences for each of said nucleic acid molecule(s) extracted from said sample; generating a plurality of sub-units of nucleotide sequences from one or more individual short strings of nucleotide sequences; accessing a database comprising nucleic acid sequences; performing probabilistic matching comprising comparing said plurality of sub-units of nucleotide sequences to said nucleic acid sequences in said database, calculating the probability of a sequence match between said plurality of sub-units of nucleotide sequences and said nucleic acid sequences in said database, and producing a probabilistic result; and identifying said biological material using the probabilistic result.
