Doctor did KOH scrape on potential fungal rash, it didnt detect fungus so now he feels it may be something else but I forgot to mention I shaved with a manual razor over the spot that morning barely an hour beforehand. Would that affect the results?

Dermatologist did scrape test (KOH test) on assumed ringworm but didnt see fungus. However I had just shaved with a manual razor over the ringworm spot less than an hour before. Could this have affected the test by removing the top layer of skin?
