d. "I should limit salty foods the day before the test."
C
Cortisol levels are collected during both the day and night to take into account alterations asso-ciated with circadian rhythms. The laboratory test does not require the patient to be fasting. In-creases in activity levels may promote stress and alter the test results. Dietary intake will not af-fect the test results.
