In brief: None or cultures
Cellulitis is a clinical diagnosis, which means doctors may diagnose it on history and physical exam alone.
Cellulitis has a characteristic look and presents as an area of redness, swelling and warmth. Doctors can do wound or blood cultures, but these tests will not help make a definitive diagnosis of cellulitis.

In brief: Blood culture
Test blood to r/o blood infection and check CBC and differential but most cases od cellulitis are diagnosed by a localized redness , swelling and pain of the affected skin site.
