What is UIBC test?

UIBC test is used to calculate Transferrin-iron saturation percentage(TS%). TS% is also reflective of iron binding capacity and its transport capacity. UIBC helps in evaluating TS%, which below 20 indicates iron deficiency and above 40 indicates iron loading. Blood transfusions, pregnancy and other factors may affect the result of UIBC test.

Why is UIBC test suggested?

UIBC test is often suggested withother iron tests.

  • To test body’s capability of iron transport.
  • When it is hinted that body iron is too low or too high.
  • When hemoglobin or hematocrit are low.

The UIBC test is done like a common blood test for a patient.

  • The injection site is disinfected.
  • Blood sample is extracted from the arm.
  • A dressing is placed at the injection site.
  • Transferrin is measured from the sample by laboratory methods.

The UIBC test may be performed along with iron serum and TIBC.

What are the parameters measured in UIBC?

The UIBC is measured for a complete blood count. It is done by measuring saturation of transferrin saturation in sample.
