Percent Match Algorithm showing percentage of allele match between original patient tissue and P1 of fresh and cryopreserved patient tissue. Samples with no growth excluded
^a PT148 frozen tissue was from P2 rather than P1
^bNo patient tissue was available for STR analysis so match shown is between Fresh and Cryopreserved samples
