TIBC (Total Iron Binding Capacity)

TIBC (Total Iron Binding Capacity) is a vitamins &nutrients biomarker that Measure of blood's capacity to bind iron The normal reference range is 250-450 μg/dL. Regular testing helps track changes and identify potential health issues early.

6 out of 10 major blood testing providers include TIBC (Total Iron Binding Capacity) in their standard panels. These include Superpower, Blueprint, Mito Health and others.

For most people, testing TIBC (Total Iron Binding Capacity) 2-4 times per year is recommended to establish baseline levels and track trends. If you have abnormal results or are actively working to optimize this biomarker, more frequent testing (quarterly) may be beneficial. Always consult with your healthcare provider for personalized testing frequency recommendations.

The standard laboratory reference range for TIBC (Total Iron Binding Capacity) is 250-450 μg/dL.
