Interleukin-4, Serum

 $253.49

This test measures interleukin-4 (IL-4), a signaling protein that helps regulate immune responses and plays a key role in allergic and inflammatory processes. IL-4 levels may be evaluated to assess immune system activity and support the investigation of allergies, asthma, autoimmune conditions, and other immune-related disorders.

Intrinsic Factor Blocking Antibody

 $25.49

Intrinsic Factor, produced by cells lining the stomach, binds Vitamin B12 (cyanocobalamin) to facilitate absorption of the vitamin. Blocking antibody impedes the action of Intrinsic Factor as observed in approximately half of the patients who develop pernicious anemia.

Biomarkers
  • Ferritin Reflects your body's stored iron levels. Low levels point to iron deficiency; high levels can indicate iron overload or, since it's also an inflammation marker, other conditions.
  • Iron % Saturation The percentage of transferrin (your iron-carrying protein) that's currently occupied by iron — a key marker for detecting iron deficiency or overload.
  • Iron, Total Measures the iron circulating in your blood, used along with other markers (like ferritin and TIBC) to evaluate for iron deficiency or overload.
  • Total Iron Binding Capacity (TIBC) Total Iron-Binding Capacity — reflects how much transferrin (the iron-carrying protein) is available in your blood, used with iron and ferritin to evaluate iron status.

Iron, Total and Total Iron Binding Capacity

 $8.49

This test checks for iron levels and the body's capacity to bind iron, helping to identify conditions like anemia or hemochromatosis. It helps doctors tell the difference between low iron levels due to a lack of iron and those caused by other health issues. The test looks at how much iron is attached to a protein called transferrin and calculates how much transferrin could carry iron if it was fully loaded. This gives doctors important information about iron in the body, which is crucial for diagnosing conditions related to too little or too much iron.
