The ACTH test is usually requested by the doctor at the same time as measuring cortisol in order to evaluate the relationship between these two hormones, as ACTH stimulates cortisol production.The normal value of ACTH in the blood rises to 46 pg / mL and may vary depending on the laboratory in which the test is performed and the time of the sample, since levels of this hormone vary during the day and the sample is recommended by Morning.
