AMT Certified Medical Lab Assistant - Free Test Sample Questions

Which of the following is tested to discover reticulocyte counts?

Correct Answer:
whole blood.


the correct answer to the question of which sample is tested to discover reticulocyte counts is whole blood. reticulocytes are immature red blood cells (rbcs), and their count is a useful indicator of bone marrow activity and the body's capability to produce red blood cells. this test is particularly important in diagnosing and monitoring conditions that affect rbc production, such as anemia and bone marrow disorders.

whole blood is required for this test because reticulocytes are present in the bloodstream for about two days before maturing into fully functional red blood cells. the test cannot be effectively conducted using plasma, as plasma is the liquid component of blood from which cells have been removed. similarly, direct testing of bone marrow is not necessary for measuring reticulocyte counts because the focus is on evaluating the cells that have been released into the circulation.

the reticulocyte count is typically expressed as a percentage of the total red blood cell count or as an absolute number. an increase in reticulocyte count can indicate that the bone marrow has increased red blood cell production, which may occur in response to conditions such as significant blood loss or successful treatment for anemia. conversely, a low reticulocyte count might suggest impaired production of red blood cells, which can be due to various causes including bone marrow failure or chronic diseases.

in summary, whole blood is essential for conducting a reticulocyte count, making it the correct answer. this test provides valuable information about the rate at which new red blood cells are being produced, thus giving insight into the health and functionality of the bone marrow.
