Reticulocyte Hemoglobin
RET HE
Description
"Reticulocyte Relative" test calculates the percentage of new red blood cells compared to the total red blood cell count. It’s commonly ordered to assess bone marrow response in cases of anemia, blood loss, or marrow dysfunction. Elevated percentages may indicate active red blood cell production, while low results suggest impaired marrow activity. This test helps doctors determine the stage of recovery or disease progression. Regular tracking supports treatment planning and ensures red cell production remains on track.

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: 30.00–36.00 pg
SI Unit: 30.00–36.00 pg
Normal Range
For All Individuals:
Conventional Unit: 28.0–35.0 pg
SI Unit: 28.0–35.0 pg
Results That Differ From The Norm (Direct and Indirect Causes)
Decreased levels may indicate:
Alcoholic liver disease (Liver damage due to excessive alcohol consumption)
Aplastic anemia (Bone marrow failure resulting in decreased red blood cell production)
Celiac disease (Autoimmune disorder affecting the small intestine)
Chronic kidney disease
Chronic liver disease
Crohn's disease...
Key Reasons For Testing
Iron Deficiency Assessment: Measures hemoglobin content in reticulocytes to diagnose and manage iron deficiency anemia.
Erythropoiesis Evaluation: Reflects the hemoglobinization status of new red blood cells, providing insights into bone marrow function.
Anemia Differentiation: Differentiates iron deficiency anemia from other causes of microcytic anemia based on hemoglobinization.
Treatment Monitoring: Tracks response to iron therapy or erythropoiesis-stimulating agents, guiding treatment adjustments.

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.
