Book Test

REASON FOR TESTING OF RETICULOCYTE COUNT


Reticulocyte count is generally measured in the following cases:

  • To monitor therapy response of a patient of anemia.

  • To determine the functionality of the bone marrow.

  • To differentiate whether cause of anemia is diminished activity of bone marrow or it is due to increased peripheral destruction of RBC.


WHAT IS BEING TESTED IN RETICULOCYTE COUNT


Reticulocyte are an immature form of RBC (carriers of oxygen in the body). Lifespan of a reticulocyte in the blood stream is approximately 2 days after which it converts into RBC. This test measures the level of Reticulocyte in the body.


INTERPRETATION OF RETICULOCYTE COUNT TEST RESULT


Low values may indicate

  • Suppressed bone marrow function. For example, in cases of aplastic anemia and iron deficiency anemia.

  • Certain long term infections or use of certain drugs.


High values any indicate.

  • Increased proliferation capacity of bone marrow which can occur at high altitudes, during increased bleeding or in cases of therapy response to anemia.


RETICULOCYTE COUNT REFERENCE RANGE


  • Adults: 0.5 - 1.5 %
  • New born: 3 - 6 %

RETICULOCYTE COUNT RELATED TESTS


Reticulocyte Count test is done in conjugation with CBC, Anemia Profile tests like Serum Iron.
