How does ferritin determine haemoglobin count?

Question

My ferritin level is low,I am on ferrous sulphate but my haemoglobin count is normal,what does this mean?

Answer 1

It only means that you don't have iron-deficienct anemia. Otherwise they're not related. Without more information about you, it is hard to impossible to tell you anything else besides that. There is likely a cause for your low iron, and you will likely get further tests to figure that out.

Answer 2

Basically it means the ferrous sulphate is working to increase the amount of iron available in your body to make Haemoglobin (Hb) and stop you becoming anaemic, if your ferritin is low your bodies stores of iron are not yet back to normal and you need to continue treatment for everything to get back to normal.

Haemoglobin (Hb) contains about two thirds of the bodies Iron, and needs iron (in the haem bit of the molecule) in order to function correctly (i.e. carry oxygen around the body).
The iron in the Hb comes from your bloods stores, and Ferritin is a water soluble protein that is one of these stores.
If ferritin is low you have low iron stores, this will be why you are on ferrous sulphate (to increase the iron available in you blood, which can then make Hb)

I guess that before treatment began you had Iron Deficient Anaemia (IDA) where you do not have enough iron in the body to make Hb You probably initially had both low ferritin and low haemoglobin levels, probably also with smaller red cells (a low MCV and low MCH on the blood test)
The reason you needed ferrous sulphate would be to increase the amount of iron available for making the Hb.
Once you started getting iron (from the ferrous sulphate) the body would first get your Hb back to normal because you need Hb in the blood to carry oxygen around. Once Hb is normal your ferritin levels can then start to increase. The following links may be useful

Answer 3

Ferritin is the storage form of iron. It simply means your iron stores are low, even if the mobilized iron in your blood is normal.

Answer 4

your blood count//Ferrous for iron
