Representative images of the qualitative results ( Figure 2 ) shows 1) the NINA heater is capable of supporting LAMP, 2) that samples incubated in the NINA heater give results that are virtually identical to those incubated in parallel in the GeneAmpH 9600. For both incubators the turbidimetric readout method (Figure 2A ) is difficult to interpret, but turbidity due to accumulating LAMP product is observed (relative to the notemplate control, or NTC). The fluorescence of the Calcein reagent when illuminated with a UV lamp ( Figure 2B ) is more easily seen as an increase in intensity (relative to NTC) for the dilutions that are .1 pg/mL. Note that there is some background Figure 3B ) reveals a mean difference (ESE -NINA) of 226 FIU, no dependence of difference on mean, and all differences lie within the 62s interval that indicates the differences are random, not systematic. Although these experiments were intended to quickly assess the agreement between heater types and were not designed to rigorously define the dose response relationship of a nascent assay, closer inspection of the FIU for each concentration ( Figure  3A ) reveals a general increase in response with increasing dose, within the experimental noise limits of this admittedly small sample set. As with the qualitative assay demonstration, considerable background fluorescence was observed in NTC reactions in both heaters ( Figure 3A and 3B) .
