What causes high TIBC and low TSH 3?

High TIBC and low TSH 3 can be caused by many reasons.

If your TIBC is in between 250 mcg/dL and 450 mcg/dL and your TSH 3 is in between 0.55 uIU/mL and 4.78 uIU/mL then you need not worry as these are the normal ranges for TIBC and TSH 3 respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.

Some examples of conditions that can increase or decrease TIBC levels include:

• Iron deficiency
• Iron poisoning
• Inflammation
• Chronic liver disease
• Hemochromatosis
