Narrative:

We had been watching our fuel since we had the APU running for almost 2 hours due to extreme heat and a slow load team. As we took the runway I thought we had gone below required fuel on the release. We had been cleared for takeoff; I asked to cancel takeoff clearance to clear the runway and confirm fuels with [operations]. We accomplished that and after I called [operations] I realized I had been using takeoff fuel not required fuel. We in fact had plenty of fuel to depart. We reentered the line for the runway and departed uneventfully.as a crew we had just focused in on the wrong number on the release. I was coming off of a month of vacation so I wasn't as sharp as I needed to be on this day. Also the long wait followed by all the activity happening at once for departure did not help. I need to be a little more vigilant to what I am looking at on the release regardless of what is going on. I am glad we took the time to confirm things with [operations]. It resulted in a little embarrassment for me but in the end we took a conservative route; we consulted with [operations] and the cargo moved safely.
