In the iron deficiency anemia case, what does a negative Prussian Blue stain indicate?

Prussian blue (Perls) staining detects ferric iron stored in bone marrow macrophages, mainly in ferritin and hemosiderin. A positive stain means there are iron stores present; a negative stain means there is little to no stored iron. In iron deficiency anemia, the body's iron stores are exhausted, so there is essentially no storage iron for the stain to bind, yielding a negative result. This pattern specifically indicates depleted iron stores, helping distinguish deficiency from situations where stores are normal or increased, which would produce a positive stain.
