Description

"Reticulocyte Absolute" test measures the number of young red blood cells in your blood to assess how actively your bone marrow is producing them. It’s often used to evaluate anemia, blood loss recovery, or bone marrow health. A high count may indicate your body is compensating for blood loss, while a low count can point to reduced marrow function. Doctors rely on this test to guide treatment decisions and monitor red blood cell regeneration over time.

Hematology Group, Blood Count Complementary Group

Test Group Description

Blood Count Complementary Group: This set of tests supplements basic blood count assessments, providing additional information to further characterize blood cell composition and identify potential abnormalities. Hematology Group: Tests within this group focus on evaluating various aspects of blood health and function. These assessments provide insights into red blood cells, white blood cells, platelets, and other components of the blood.

Optimal Range

For All Individuals:

  • Conventional Unit: Not Available

  • SI Unit: Not Available

Normal Range

For All Individuals:

  • Conventional Unit: 20.0–115.0 ×10⁹/L

  • SI Unit: 20.0–115.0 ×10⁹/L

Results That Differ From The Norm (Direct and Indirect Causes)

Increased levels may indicate:


  • Acute blood loss

  • Autoimmune hemolytic anemia (Immune system attacks and destroys red blood cells)

  • Chemotherapy (Treatment with drugs to kill cancer cells)

  • Erythropoietin administration (Administration of erythropoietin hormone)

  • Hemolytic anemia (Increased breakdown of red blood cells)

  • Hemo...

Key Reasons For Testing

  • Bone Marrow Function: Indicates the rate of red blood cell production and turnover.

  • Anemia Evaluation: Helps differentiate types of anemia based on bone marrow response.

  • Treatment Response: Tracks bone marrow's response to therapies for anemia or hemolytic disorders.

  • Blood Loss Monitoring: Assesses recovery and intervention needs following acute or chronic blood loss.

Important Note

Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.


Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
