What Causes Abnormal Total Iron Binding Capacity?

Abnormal total iron binding capacity can have various causes, ranging in severity from 'needs attention' to 'life-threatening'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose abnormal total iron binding capacity, we could:

Research the topic
Find a doctor with the time
Use a diagnostic computer system.

The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "abnormal total iron binding capacity" as a symptom. Here are three possibilities:

Hemochromatosis
Iron Deficiency Anemia
Cirrhosis Of The Liver

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:

frequent severe abdominal pain

white inside lower eyelids

weak appetite

high serum iron

red palms/fingertips

low energy/stamina

very low ferritin levels

low sperm count

pale fingernails

being medication sensitive

minimal body hair

darker/redder skin color

... and more than 20 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of abnormal total iron binding capacity:

Cause	Probability	Status
Cirrhosis Of The Liver	95%	Confirm
Hemochromatosis	29%	Unlikely
Iron Deficiency Anemia	1%	Ruled out

* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate having had recent lab tests, The Analyst™ will ask further questions including this one:

Iron, TIBC (Total Iron Binding Capacity). Unit: ug/dL [umol/L]

Possible responses:

→ Don't know
→ Under 150 [26.9]
→ 150-239 [26.9-42.8]
→ 240-450 [42.9-80.6] (normal)
→ Over 450 [80.6]

Based on your response to this question, which may indicate very low TIBC, low TIBC, normal TIBC or elevated TIBC, The Analyst™ will consider possibilities such as:

Cirrhosis of the Liver

Hemochromatosis (Iron overload)

While low TIBC is commonly explained by the presence of hemochromatosis, it can also be caused by hypoproteinemia from malnutrition, anemia with infection and chronic disease, and nephrosis.

Iron Deficiency Anemia

While TIBC is commonly elevated in cases of iron deficiency anemia, it is also increased through the use of oral contraceptives and in pregnancy, blood loss and acute liver damage.

... and also rule out issues such as:

Hemochromatosis (Iron overload)
