A PCR reаctiоn is perfоrmed аnd the results аre being analyzed.  The pоsitive control has a band at the expected size, the negative template control has a band at the same size as the positive control; the contamination control has no band; the amplification control has a band of the expected size.  All of the patient samples that were run had a band the same size as the band seen in the positive and negative template control wells.  How should you interpret these results.
