How serious is a hemoglobin count of 16.5 in a woman?

A hemoglobin of 16.5 is actually considered normal for a woman.
If it is any higher, that is when a doctor will show concern and
order other tests to determine why it is too high.

The way to count up by 55s is to start at 55 and add 55 more. So the answer would be 110. Add 55 to that and it would be 165. Adding 55 to that would be 210, then 265, and so on.
