Iron Studies

Iron plays a vital role in the function and development of cognition and behavior. Low levels of Iron have been associated with symptoms such as fatigue, poor hair growth, poor immunity, palpitations, exercise fatigue and autistic behavior.

An Iron studies test looks at:

Serum Iron

A Serum Iron test measures how much iron is in the serum of the blood.   Serum is the liquid component in blood; this is the substance that is left when clotting factors and red blood cells have been removed.


10.0 – 30.0



Transferrin is a protein transporter in the blood that moves iron throughout the body.


This biomarker can indicate whether there are issues with transportation of iron or whether there is too much or too little iron in the blood. Transferrin levels may also be reduced with inflammation.

2.10 – 3.80



This is a percentage measurement of how much iron is bound to the blood protein transferrin.

Transferrin saturation is a helpful indicator of potential iron overload. It can be useful in the diagnosis of Haemochromatosis.

Saturations of less than 20% may indicate iron deficiency, whereas saturations of over 45% may suggest overload.

15 – 45%



Ferritin levels reflects the amount of stored iron in the liver.


Elevated levels reflect iron overload which may be due to excess dietary/supplementary levels or haemochromatosis.

Elevated levels can also be associated with inflammation, liver disease or malignancy.


Decreased levels are associated with low levels of dietary/supplemental iron, menorrhagia or occult bleeding.
