In brief: Not yet

Most circadian rhythm testing is based on levels of melatonin in the body.
These tests are usually only performed in research laboratories and not in your doctors office. Sometimes questionnaires and a form of sleep wake monitoring called actigraphy is helpful in determining an individuals general circadian rhythm.

You can purchase online oral swab melatonin kits if you are interested which are relatively accurate. I don't recommend because it is a lot of work and you are looking for a trend. Can get costly.

In brief: Circadian rhythm

There are blood tests that can be done, but we don't use them to determine someone's circadian rhythm.
There are hormones that fluctuate predictably with the circadian rhythm, like growth hormone, acth, cortisol and tsh. A good way to "test" your circadian rhythm is your temperature, but the best determinant of your rhythm is your sleep pattern...When you go to bed and sleep and when you wake up.
