What usually happens next

Inflammation, infection, alcohol and fatty liver raise ferritin far more often than iron overload does.

A transferrin saturation decides it: if that's normal, iron overload is unlikely.

When a ferritin can read wrong

Ferritin is also an inflammation marker: an infection, an inflammatory condition, fatty liver or heavy drinking can push it up and hide low iron. In those cases a ferritin under 70 ng/mL can still mean iron deficiency.

Questions

Is a ferritin of 150 ng/mL normal?

A ferritin of 150 ng/mL is above 150 ng/mL, the WHO's line for possible iron overload in women (200 in men). The usual range is about 30 to 300 ng/mL, depending on the lab, sex and age.

Is a ferritin of 150 ng/mL too low?

Under 15 ng/mL means iron stores are empty, and under 30 they're likely depleted. Between 30 and 45 it's low-normal; what matters is whether you're anaemic and why.

Can I take iron with a ferritin of 150 ng/mL?

Iron is something to replace with your doctor, after finding out why it's low, because taking it when you don't need it can do harm.
