just add an RTminus control. Do duplicate reverse transcription reactions with your samples but leave out the RT enzyme (=RTminus control) in one (just add water instead). Then do PCR with both. If your primers detect gDNA and there was some gDNA left in your RNA prep you will get a signal in the RTminus control.
right, i thought so complicated!

Just take some of your RNA sample as template for standard PCR!
