Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.

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

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