Before the test
No fasting is generally needed. Recent transfusion or treatment may affect interpretation.
Clinical interpretation
Laboratory results should be interpreted by a qualified professional using the correct reference interval, method, symptoms, history and other findings. A normal or abnormal value rarely confirms or excludes a condition by itself.
What the test is used for
Distinguishing reduced production from blood loss or destruction, and monitoring marrow recovery or treatment response.
How the test is performed
A blood analyser or flow method identifies reticulocytes using nucleic-acid staining and reports a percentage and/or absolute count.
Conditions and diseases considered
Used in investigation of anaemia, haemolysis, bleeding, marrow suppression and recovery after treatment.
Recommended further tests
CBC and film, bilirubin, LDH, haptoglobin, iron studies, B12/folate and direct antiglobulin testing.
