Purpose
The Iron Blood Test measures the amount of iron circulating in the blood. Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen throughout the body. This test plays a crucial role in diagnosing iron-related conditions such as iron deficiency anemia, iron overload (hemochromatosis), or chronic diseases affecting iron metabolism.
It is important because abnormal iron levels can lead to fatigue, weakness, and organ damage if left unmanaged. The test helps clinicians evaluate nutritional status, investigate symptoms like tiredness and pallor, and monitor iron therapy.
Other medical laboratory tests that are commonly performed alongside the iron test include total iron binding capacity (TIBC), ferritin test, transferrin saturation, Complete Blood Count (CBC), and vitamin B12 and folate tests (if anemia is suspected).
Patient Preparation
No special preparations are required.
Samples
1ml with a minimum volume of 0.7ml of serum or plasma collected in a Gel-barrier, red-top, or green top tube (lithium heparin). Avoid using EDTA, oxalate, or citrate plasma. Separate the Serum or plasma within 45 minutes of sample collection. Store the sample at room temperature.
Reference Range
18-169 µg/dl
Results Turnaround
Within 24 hours after sample collection.
Diseases / Diagnostic indicators
The Iron Blood Test evaluates disorders related to iron metabolism and transport in the body. It helps diagnose conditions such as iron deficiency anemia, hemochromatosis (iron overload), chronic inflammation, and malnutrition.
Some possible outcomes of the test:
Low Iron Levels:
May indicate iron deficiency anemia, chronic blood loss (e.g., from ulcers or menstruation), poor dietary intake, or chronic diseases that interfere with iron absorption or transport.
High Iron Levels:
May suggest hemochromatosis, excessive iron supplementation, multiple blood transfusions, or liver disorders that affect iron storage and regulation.
Normal Iron Levels:
Typically indicates adequate iron balance, but further testing (like ferritin and TIBC) may still be needed to fully assess iron stores and transport capacity.
