Paramedics contacted the force 13 minutes later and said they had treated the teenager at a residential address in Blackshaw Road, Tooting, about half a mile away.
He was taken to hospital in west London and remained in a serious condition on Friday morning.
His family were informed and officers from the Trident and Area Crime Command have launched an inquiry, the Met said.
No arrests have been made but officers have urged witnesses or others with information to come forward.
