About Our Iron & Total Iron Binding Capacity (TIBC) Test

Note: Fasting is not required for this test.

Our Total Iron Binding Capacity (TIBC) Test includes an Iron Test and is used to see if there is too much or too little iron in the blood. Iron moves through the blood attached to a protein called transferrin. The TIBC Test is often used to differentiate between anemia types and gives more iron statistics than the Iron Test alone.

Iron is a mineral that is needed by your body for the production of hemoglobin, energy, and maintaining proper muscle and organ function.

Typically iron is absorbed as a nutrient during digestion. When iron levels are too low, an individual is considered anemic. Iron deficient anemia causes weakness, fatigue, dizziness, and sometimes chest pain, headaches, aching legs and breath shortness. An overabundance of iron can lead to joint point, weakness, stomach or chest pain, and fatigue.

Iron metal poisoning can cause the following symptoms:

  • Nausea
  • Vomiting
  • Abdominal pain
  • Gastrointestinal bleeding
  • Jaundice
  • Hepatic/Liver failure

In cases of low or abnormal CBC Test results where the hemoglobin and/or hematocrit levels are deficient, the TIBC Test and/or Iron Test may be ordered.
