Why hasn't a reference range been applied to my cortisol blood test result?

Your cortisol blood test is a 9am cortisol test which is used to check your cortisol level on waking. The laboratory will apply a range if your sample was taken between 6am and 10am but if your sample was taken later in the day then the range will not be relevant to your result. If no range can be applied to your result then we will not be able to display it on the coloured bar.
