  • If you are on a twice daily dose of Hydrocortisone, stop your Hydrocortisone tablets one day before the blood test. 
  • If you are on a morning dose of Hydrocortisone only, do not take your morning dose of Hydrocortisone on the day of the blood test.

  • Please arrive at the clinic on time. (8am - 8:30am)
