Did you mean Transferrin Saturation?

Glossary Transferrin Saturation

Transferrin saturation refers to the percentage of transferrin, a protein that binds and transports iron in the bloodstream, that is saturated with iron. It is a crucial indicator of iron metabolism and can be relevant in the context of hair loss, as iron deficiency has been linked to conditions such as telogen effluvium and alopecia. Key distinguishing characteristics include its measurement through serum iron and total iron-binding capacity (TIBC), with normal transferrin saturation levels typically ranging from 20% to 50%. Monitoring transferrin saturation can help identify potential nutritional deficiencies that may contribute to hair thinning or loss.
