What the Reticulocyte Count test checks
The count is reported as a percentage of all red cells, and many reports also give an absolute number per microlitre. To see reticulocytes, the blood is mixed with a special stain (new methylene blue or brilliant cresyl blue) that shows up the leftover RNA as dark threads. They are then counted against 1,000 red cells under the microscope, or measured by an analyser.
Because anaemia itself changes the percentage, doctors often look at a "corrected" count or the reticulocyte production index. These adjust the raw figure for your haemoglobin level or haematocrit.
Why your doctor may order it
The question behind this test is simple: is the marrow making red cells too slowly, or is it making plenty that are being lost or destroyed? It's used:
- to sort out the cause of anaemia found on a CBC
- when haemolysis (red cells breaking down early) is suspected, for example with jaundice and dark urine
- after bleeding, to see recovery
- after starting iron, B12 or folic acid, as an early sign that treatment is working
- during chemotherapy or after a bone marrow transplant
How to prepare
No fasting or diet changes. Tell us about any recent transfusion, since donor blood dilutes your own reticulocytes. If you started iron or B12 recently, mention the date; doctors expect a rise roughly a week or so after starting.
Sample type and report time
A small sample in a purple-top EDTA tube, ideally tested the same day because reticulocytes keep maturing in the tube. Home sample collection is done early so the sample reaches us in good time. Report: usually the same day for samples given by 11 am.
Understanding your results
In adults, reticulocytes typically make up around 0.5–2.5% of red cells. Newborns have much higher levels. The range printed on your report is the one that applies; ranges vary by lab and method.
A high count with anaemia can be associated with bleeding, haemolytic anaemia, or a good response to treatment of a deficiency. A low count with anaemia suggests the marrow isn't keeping up, as seen in untreated iron, B12 or folate deficiency, kidney disease (low erythropoietin), aplastic anaemia or marrow infiltration. Your doctor reads the result alongside your symptoms and other tests.
FAQ
Why is my reticulocyte count high after starting iron?
That's often the expected response. The marrow releases more young cells once it has the iron it needs.
Is the reticulocyte count part of a routine CBC?
Usually not. Most CBCs don't include it, so it has to be requested separately.
Can I find a reticulocyte count test near me in Banur?
Yes. If you need a reticulocyte count test near me in Banur, Alpha Laboratory takes the sample and reports routine requests the same day.
Does a low count always mean a marrow problem?
No. Simple deficiencies are a common cause, and the count rises once they are corrected.
