I had a throat swab done because of a sore throat with no other symptoms. culture came back positive for non typable h. influenza. how is this possible?

See below: No all H inluenzae bacteria cause disease. There are six major types and type B causes most infections in humans. There are also other types of bacteria which do not fall into the six known categories and are called untypable.
