My school did not list labs separately on my transcript as the lab grade was factored into the overall class grade. I know as of last year there was a little box that said "with lab" to check on the application. Each class was listed as 4 credits on my transcript. I plugged the classes in exactly as they were on my transcript and clicked the "with lab" button if applicable. I had no issues during verification. I don't know if anything has changed as far as their handling of that this year.
