My s-cortisol level are 288 & s-ferritin 13. is that ok? friends say cortisol have to be 400+ & ferritin 100+. do not know the referens.

Discuss with yr doc: My ferritin reference range for adult females is 10-150. You're toward the low end, & low is caused by iron deficiency: get checked for iron deficiency & possible anemia as well. Serum cortisol levels are affected by numerous variables, esp. time of day: range AM: 7-25 mcg/dL & PM: 2-14 mcg/dL. You should discuss your findings with your primary medical provider or specialist. Hope that helps.
