Check up vs. checkup

Checkup is a noun. It’s what you get when you visit your doctor for a routine examination. The word doesn’t work as a verb. When you need a verb, use the two-word check up. It’s one of many phrasal verbs with corresponding one-word nouns. For example, see also burn out and work out.

In British publications, checkup is often hyphenated—check-up—but the unhyphenated version appears as well.
