I see that you are a male.
I am female and have anemia, and was reffered to a hematologist.
First, let me explain that your iron levels mean nothing. You could have an iron count of 60 one minute, get another blood draw a minute later and it could be 40. They fluctuate minute by minute. So that is not a good indicator of anything. Only when combone with other things.
I see they tested you for Ferritin. But did they also test you for TIBC(Total Iron Bonding Capacity) and Iron Saturation? These two tests, combined with Ferritin and a CBC with diff's gives the broader picture.
My ferritin was an 8. But mine was caused by my periods. My ferritin still runs low, but the rest of my numbers are fine.
The biggest thing is. How do you FEEL? If you are extrmemly tired, pale, etc.....then I would follow up on this.
I would NOT take iron because you are a man, and do not bleed once a month. You could overdose on it. Only take iroon if prescribed by a Dr.
If you are donating blood, that is a lot of blood you are donating.Even just one time.
That could be a very good reason. Ferritin levels take MONTHS to regulate.
If your RDW-CV is good and your MCV is at least 85, HGB seems great,HCT is good and your RBC is excellent(I wish I had those numbers), I would not base my fears on Ferritin alone. And certainly not by iron alone.
It is true, that when your ferritin becomes very low, it starts drawing from your Hemoglobin. But everybody is different.
I would see the hematologist. They know exactly what blood tests to run. I wouldn't even worry about this. My heme Dr told me that because not everyone get their Ferritin tested, people have no idea they are even low. And most people's Ferritin levels are lower then they think.
And, for some people, 8 is normal. Like me. I am lucky I get up to 35.
