If the tech wouldve found the temp to be an issue, she wouldve made you immediately give a second sample and under observation.

Since this did not happen, you have nothing to worry about. The reason why the tech checks the temp is to see that you didnt use a substituted sample. Temp has no bearing on whether a sample tests positive or negative therefore, temp ceases to be a factor once the sample is bagged and sent off for the analysis.
