In addition to lowered susceptibility to template (amplicon) contamination, the lack of a nucleic acid amplification step in these assays reduces sample-to-answer time and susceptibility to PCR inhibitory substances in the samples, making such assays popular in laboratory settings where assay speed and robustness in face of potentially variable sample quality are critical factors.
