The Serum Total Iron Binding Capacity (TIBC) Kit is primarily used in clinical diagnostics to assess iron metabolism and related disorders. It measures the total capacity of transferrin to bind iron in the blood, providing critical insights into conditions like iron deficiency anemia, hemochromatosis, and chronic diseases affecting iron levels. By evaluating TIBC, healthcare professionals can differentiate between various types of anemia and monitor the effectiveness of iron therapy. This kit is essential in routine blood tests to ensure accurate diagnosis and management of iron-related health issues.
