Quick answer
The Reticulocyte Count Test costs ₹350 at Live Line Health Care. Counts young red blood cells to show whether your bone marrow is keeping up with demand. No fasting is needed. It uses a blood sample and the report is usually ready within 24 hours. Book home sample collection or visit any of our 45 centres.
Also known as: Retic Count, Retic Test, Reticulocyte Test, Reticulocyte Percentage, Reticulocytes
What is the Reticulocyte Count Test?
The reticulocyte count test measures how many young red blood cells are circulating in your blood. Reticulocytes are newly released from the bone marrow and mature into full red cells within a day or two. Since they are freshly made, their number gives a direct view of how actively your marrow is producing red cells right now. The result is usually reported as a percentage of all red cells, and some reports add an absolute count.
Think of low haemoglobin as the problem and the reticulocyte count as the clue to its cause. If haemoglobin is low and reticulocytes are high, the marrow is working hard to replace cells lost through bleeding or destroyed early, as in haemolysis. If both are low, the marrow is not keeping up, perhaps from a shortage of iron, vitamin B12 or folate, kidney disease or a marrow problem. This is why doctors ask for it after a CBC has shown anaemia, rather than as a routine first test. It is also one of the earliest signs that iron or B12 treatment has begun to work, rising well before haemoglobin does.
What it measures: The share of young, newly released red blood cells among all the red cells in your blood.
Parameters included (1)
- Reticulocyte Count (%)
Why is this test done?
- Finding out why someone has anaemia after a low CBC result
- Checking for haemolysis, where red cells break down too early
- Confirming recovery after bleeding or after iron, vitamin B12 or folate treatment
- Monitoring bone marrow recovery after chemotherapy or a marrow condition
- Follow-up in conditions such as thalassaemia and sickle cell disease
When should you get tested?
- Anaemia on a CBC with no obvious cause
- Yellow eyes or dark urine along with tiredness, which can suggest red cell breakdown
- Starting iron or vitamin B12 treatment when your doctor wants to confirm a response
- Low counts of more than one type of blood cell
- A family history of inherited anaemia
How to prepare for the Reticulocyte Count Test
- 1Have your food and water as usual, as meals have no effect on reticulocytes.
- 2Note the date you started iron, vitamin B12 or folic acid, because reticulocytes peak about 7 to 10 days after treatment begins.
- 3Tell staff about any recent blood transfusion or major bleeding, as both change how the result is read.
- 4Bring your latest CBC, since your doctor needs the haemoglobin or PCV to correct the percentage.
Reticulocyte Count Test normal range
| Parameter | Typical reference range |
|---|---|
| Adults | 0.5–2.5% |
| Absolute count, if reported | 25,000–1,00,000 /µL |
| Newborns | 2–6%falls to adult levels within weeks |
A percentage can look falsely high in anaemia, because there are fewer mature red cells. Doctors often correct it for the PCV. Ranges are typical adult values and vary between labs, age and sex. Always use the range printed on your report and discuss results with your doctor.
Understanding your results
- A high count with anaemia suggests the marrow is responding, usually to recent bleeding or haemolysis. Your doctor may add tests such as LDH, bilirubin and a Direct Coombs Test.
- A low or normal count with anaemia suggests the marrow is underproducing, which can be seen in untreated iron, vitamin B12 or folate deficiency, kidney disease or bone marrow failure.
- A rising count 1 to 2 weeks after starting iron or vitamin B12 is a good sign that treatment is reaching the marrow.
- Doctors may calculate a corrected count: reticulocyte % × (your PCV ÷ 45). A reticulocyte production index above about 3 generally shows a good marrow response, and below 2 an inadequate one.
- A very low count with low white cells and platelets needs prompt review, as it can point to a bone marrow problem such as aplastic anaemia.

Reticulocyte Count Test – FAQs
What is the price of the Reticulocyte Count Test?
The Reticulocyte Count Test costs ₹350 at Live Line Health Care, at all 45 centres and for home sample collection.
What does a high reticulocyte count mean?
It means your marrow is releasing more young red cells than usual. This happens after bleeding, when red cells are breaking down early, or when anaemia is responding to treatment. It can also rise in pregnancy. Your doctor will read it with your haemoglobin and other results.
What does a low reticulocyte count mean?
It means fewer new red cells are being released. If you also have anaemia, the cause may be a shortage of iron, vitamin B12 or folate, long-standing kidney disease, or a bone marrow problem. Your doctor may order further tests. A low count with normal haemoglobin is less often a concern.
How is a reticulocyte count different from a CBC?
A CBC counts all your red cells and shows how much haemoglobin you have today. A reticulocyte count shows how many new red cells are being made. The CBC tells your doctor that anaemia is present, and this test helps explain whether the marrow is keeping up.
How soon after starting iron tablets does the count go up?
Usually within about 3 to 5 days, with a peak around 7 to 10 days after treatment begins. This happens well before haemoglobin improves. Your doctor may check it if your anaemia is not improving, or to confirm that the diagnosis and treatment are right.
Why was this test ordered when my haemoglobin is only slightly low?
Because it helps sort anaemia into two groups: making too few red cells, or losing them too quickly. That answer guides the next tests and can avoid unnecessary ones. Even a mild anaemia can have an important cause, so your doctor may want this information early.
Can a recent blood transfusion affect the reticulocyte count?
Yes. Donated cells dilute your own red cells, which lowers the reticulocyte percentage, and a raised haemoglobin may also reduce how hard your marrow is working. Tell staff the date of any transfusion so that your doctor can interpret the result correctly.
Where can I get the Reticulocyte Count Test done?
At any of our 45 Live Line Health Care centres in 40 cities across Andhra Pradesh and Telangana, including Hyderabad, Visakhapatnam, Warangal, Kakinada and Nellore, or book home sample collection.
