In this case the doctor explicitly said it was to reduce costs, although the other test is preferable from a diagnosis perspective. Like I mentioned previously, if the reason the doctor gave was that the more expensive test was also less useful or had other negative consequences I didn't think of, then I'd appreciate that. To simply rule out the more expensive test based on cost seemed at ends with what I wanted - again as insurance was paying the tab.
