First Check Home Test Came Up Negative, Should I Still Use Quick Fix Plus?

[Burnt Toast]

I have practiced the temp a couple times. It usually stays between 96 and 98 with two heat pads on it. Now I would think that is the heat of the bottle moreso than the liquid. Would I be right to assume the liquid is probably a degree or two higher than what the readout on the QF bottle says?

The acceptable temperature range is 90-100 F. You only need to be concerned that the sample temperature is within this range when you hand it over to the collector.
