Benefits of Lab Testing in Hemochromatosis
Some estimates show 1 in 9 people of Northern European descent are carriers of the genetic mutation that can cause this disease. Entire families may be impacted without their knowledge.
For something so common, one might think that everyone would have heard of this condition, that it would be part of routine blood testing done by physicians, and that people with the condition would have a great support network and understanding by their doctors, friends, and community.
And yet, in reality, hemochromatosis is frequently misdiagnosed by doctors or not diagnosed at all, so people often suffer for longer than they need to, feeling alone in their deteriorating health. Many times their friends and family members have never even heard of the condition, leading to feelings of being an outsider with a strange condition no one can pronounce.
Reasons for Doing Lab Tests for Iron Overload
Using Lab Tests to Diagnose Hereditary Hemochromatosis- A Hemochromatosis Diagnosis is often accomplished by a combination of blood tests used to look at iron markers in the body, and then confirmed by a genetic test. As a genetic condition that is passed down to other blood relatives, many times a healthcare provider is alerted to check for this condition after another family member tests positive.
Using Lab Tests to Monitor Your Iron Overload- Another use of lab tests after a diagnosis of hemochromatosis has been established is to monitor how you are handling treatment and your overall health status. If therapeutic phlebotomy has been recommended, it’s important to monitor your blood levels to ensure you don’t give too much blood too fast, and on the flip-side, to make sure that you are doing the phlebotomy frequently enough.
Common Blood Tests in Hemochromatosis
Serum Iron gives us a glance at the current level of iron in our bloodstream. Serum iron is not “free iron” but rather the quantity of iron bound to transferrin in our blood.
Unsaturated/Unbound Iron-Binding Capacity (UIBC)- This is the amount of free iron in the blood, unbound and causing oxidative damage. In the unbound form, excess iron is toxic to our tissues and organs. Free iron is a “pro-oxidant” and creates free radicals that will destroy the healthy function of our cells.
Total Iron-Binding Capacity (TIBC) measures, as you might guess, the available capacity of the blood to bind iron.
Ferritin Level is the most significant lab test to monitor the state of your condition and the progress of your treatment. The ferritin test alerts us to the burden of iron in the cells. Ferritin binds excess iron, which reduces the harmful oxidation potential and toxicity of free iron. High ferritin levels are not problematic in and of themselves, but elevated ferritin most often reflects a state of excess iron.

Transferrin Saturation is a ratio of serum iron to total iron-binding capacity (multiplied by 100). This value represents the percentage of how much iron is bound to the blood protein transferrin. An elevated transferrin saturation is highly correlated with hemochromatosis.

The HFE Gene Test determines if an individual’s DNA contains any of the mutant alleles associated with hemochromatosis: C282Y, H63D, or S65C.
Additionally, the following are common blood tests for liver function, a frequently affected organ in hemochromatosis:
- AST & ALT- These are the most common. If there is damage to the cells of the liver, these enzymes may be elevated in the blood.
- ALP & GGT- Other liver markers that may be tested. If the flow of bile from the liver is impaired, these enzymes may be elevated in the blood.
- Triglycerides, Cholesterol, Blood Sugar- These metabolic markers can rise for a variety of reasons, including decreased liver function.
How to Get Tested for Hemochromatosis
Many patients who suspect they might have iron overload or who have family members who have been diagnosed can share their concerns with the physicians and ask them to run an iron panel. A complete iron panel typically includes:
- Transferrin Saturation %
- Serum Iron
These are all tested via a routine blood test and are most accurate if done fasting.
Many times doctors may not find it necessary to jump straight to the genetic testing, but if you know it runs in your family, your doctor may run the genetic test at the same time. Other times the genetics are run after abnormal numbers show up from the iron panel.
The hemochromatosis genetic testing is also a blood test and this does not need to be done fasting. The test will look to see if you have one or two copies of any of the following genes: C282Y, H63D, or S65C. Different combinations are correlated with different levels of disease—you may read more about the genetics of hereditary hemochromatosis here.
What if my doctor won’t test this for me?
I’ve gotten this question a lot. Some people don’t fit the typical profile so their healthcare practitioner doesn't think it's necessary. Or your doctor may not be familiar with hemochromatosis testing.
Direct Labs is a fantastic way to test your labs, including iron markers like ferritin and transferrin saturation % and genetic markers like C282Y, H63D, & S65C.
Reasons to use DirectLabs include:
- You have already received your hemochromatosis diagnosis and you are looking to monitor your lab tests.
- You suspect you may have iron overload, but you have yet to have any testing done.
- You have a family member with hereditary hemochromatosis, but you have yet to have any testing done (or vice versa… you have iron overload –> but your family has yet to be tested).
- You are interested in monitoring your blood work for enhancing your general health.
- You would prefer to pay a pre-negotiated lower rate directly to the lab versus going through insurance and/or your providers billing process.
- Many other lab providers do not have the Hemochromatosis DNA test available or have discontinued offering it. (I have also seen some lab companies charge a prohibitively expensive price- over $600!- whereas Direct Labs offers the DNA test at a much more reasonable price.)

Hemochromatosis testing is essential for many reasons. All the time, I hear from people who suspect that they may have iron overload. Perhaps even more common is the story of a person who has been diagnosed with hereditary hemochromatosis, but their family members have not been checked yet.
In either case, lab testing can be an important first step in identifying the root cause of too much iron. Once someone has received the proper hemochromatosis testing, they can then go about taking the necessary steps to get themselves healthier.
