Hi, I'm a 28 yr old woman and I was wondering if anyone knew if a level of 18 on a ferritin test is too low? My doctor said it's fine but the range starts at 13 and ends at almost 300? Also, I was wondering if this tends to happen in people with thalassemia? Thalassemia runs in my family but I don't know if I have it, so I'm wondering if that's why my ferritin is where it is. Any info would be appreciated, thanks.
