My 9month old son has low hb even though he seems fine and eats alright. his sickling status is negative. what can be wrong?

Many possibilities: The HGB screening test will pick up a low level in 10% of otherwise normal kids. It reflects the ability to absorb needed iron from the diet, keep an adequate supply to make new blood cells and replace old ones.Kids can grow faster than their ability to keep up. Various illnesses and other factors can keep the level down.Screening identifies kids that need further tests or just added dietary iron.

More info needed: Is patient breast or bottle fed? Has patient been on any vitamin supplement? Any iron supplement? What are the blood counts--are they really anemic or at the low normal for age? Was infant premature? How has pediatrician caring for child advised the family--including introduction of solid foods-- good luck.
