Three standard DPA 4200 instruments validated with polystyrene beads and a sensitivity challenge standard were employed during this study.
Linear and quadratic sex difference trends were also observed following both CAA and OVA dermal sensitivity challenge.
A further sensitivity challenge standard was required which would allow different instruments to be assessed and adjusted to achieve consistent results when very low contrast particles were present.
Overall, they are not appropriate to diagnose the chronic stage of infection due to limited 60-900%) sensitivity, technical challenges and lack of standardization [ 10, 13, 23].
However, the toxicity of these agents and their side effects, along with the development of resistance and differences in strain sensitivity, are challenges that must be overcome [ 10].
However, although PCR and, more recently, RT-PCR have revolutionized the diagnosis of infectious diseases by reducing the time to diagnosis and increasing the detection sensitivity, several challenges remain, including the spectrum of detected agents, which is limited by the specificity of the assays used.
Additionally, it also results in increased possibility for false-positive identifications as the false discovery rate scales with the increasing database size, greatly decreasing sensitivity; twin challenges that can only be feasibly met with dedicated/sophisticated computing resources precluding routine use at present.

However, sensitivity analyses challenged the robustness of these results.
