tibc การใช้

• See interpretation of TIBC . Low transferrin likely indicates malnutrition.
• The UIBC is calculated by subtracting the serum iron from the TIBC.
• The TIBC should not be confused with the UIBC, or " unsaturated iron binding capacity " ( and ).
• Levels of serum iron and total iron binding capacity ( TIBC ) are used in conjunction with transferrin to specify any abnormality.
• Another lab test saturates the sample to measure the total amount of transferrin; this test is called total iron-binding capacity ( TIBC ).
• These examples demonstrate that to properly understand a value for TIBC, one also must know the serum iron, the percent transferrin saturation, and the individual clinical situation.
• The ratio of serum iron to TIBC ( called iron saturation or transferrin saturation index or percent ) is the most specific indicator of iron deficiency when it is sufficiently low.
• Serum iron levels ( i . e . iron not part of the hemoglobin in red cells ) may be measured directly in the blood, but these levels increase immediately with iron supplementation ( the patient must stop supplements for 24 hours ), and pure blood-serum iron concentration, in any case, is not as sensitive as a combination of total serum iron, along with a measure of the serum iron-binding protein levels ( TIBC ).
