1. Leviticus 13:3 (ESV)
  2. Exposition

What would happen is both these criteria were met?

Leviticus 13:3 (ESV)

3 and the priest shall examine the diseased area on the skin of his body. And if the hair in the diseased area has turned white and the disease appears to be deeper than the skin of his body, it is a case of leprous disease. When the priest has examined him, he shall pronounce him unclean.

If both conditions were present, the priest would make the pronouncement that the individual was unclean. The verb “pronounce” uses a Hebrew construction for declaration. In this way, the priest would fulfill his responsibility as stated in Leviticus 10:10.
