Ferritin test

  1. I'm really confused about the ferritin test results and the range of normal.


    Male: 12-300 ng/mL
    Female: 12-150 ng/mL

    So if a male has a level of 300 or 12, is that considered "high" or "low" or within normal range? Does a doctor make a judgement that because a person has 20 they are low and encourage supplements, or do they just say it's normal, don't worry about it. On the other end if a person has a value of 295 will the doctor suspect a blood/liver disorder, or just say it's normal, don't worry about it? It seems like such a huge range of normal.

    Thanks!
