DNA profile from semen sample that have undergone test with acid phosphatase as a presumptive test on clothes can shown 100% success rate (Figure 4). While the DNA profile was from tissue paper has up to 7 in 10 sample, another three examples that didn't complete DNA profile has lost 1 of the allele only. (เหตุผลคืออะไร). These allele drop-outs were associated with the much lower average peak heights observed with tissue paper as the substrate.
