Iron & TIBC
This test measures the blood Iron, Iron Saturation, TIBC and UIBC levels. The Iron component measures the amount of iron circulating in the blood. The TIBC level measures how well proteins in the blood can bind iron. The Iron/TIBC ratio, or Iron Saturation, is calculated to determine how well the body binds iron and transports it. In iron deficiency anemia, the Serum Iron is typically low, the TIBC is high, and the Iron Saturation is low.
