Confirmed woman went out after iodine (9)
I believe the answer is:
validated
'confirmed' is the definition.
(validating is a kind of confirming)
'woman went out after iodine' is the wordplay.
'woman' becomes 'val' (val is a name for a woman).
'went out' becomes 'dated' (dating is a kind of going out).
'after' is a charade indicator (letters next to each other).
'iodine' becomes 'I' (chemical symbol).
'dated' after 'i' is 'idated'.
'val'+'idated'='VALIDATED'
(Other definitions for validated that I've seen before include "backed up" , "certified" , "proved true" .)
