Reticulocyte Count, Automated Test
This test measures reticulocytes, immature red blood cells, in a whole-blood sample. It can be ordered through Celio Health.
About this test
The test analyzes a whole blood sample, collected in an EDTA (lavender-top) tube and mixed well by gentle inversion, using electronic cell sizing and counting, cytometry or microscopy. It reports the reticulocyte count as well as the absolute reticulocyte value.
Quest lists this count as used in evaluating erythropoietic activity, the process by which red blood cells are produced. A reticulocyte result reflects that production process rather than the mature red blood cell population itself, which is why it is often read alongside other blood count values.

Additional details
What this test looks at
The test reports two related values: the reticulocyte count and the absolute reticulocyte number, both measured from a whole-blood sample. Quest lists this measurement as used in evaluating erythropoietic activity, the process by which the body produces red blood cells.
Order online and a physician order is included — no doctor's visit and no insurance needed. Your sample is collected at a Quest Diagnostics patient service center.
Laboratory results should always be interpreted by a licensed clinician who knows your health history. This page is information about a test, not medical advice.
Frequently asked questions
What does this test measure?
It measures reticulocytes, immature red blood cells, in a whole-blood sample, reporting a count and an absolute value.
How is the sample collected?
The test uses a whole-blood sample collected in a full EDTA tube, mixed well by gentle inversion, from a routine blood draw.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Why might a clinician order a reticulocyte count?
Quest lists it as used in evaluating erythropoietic activity, the process by which red blood cells are produced.
How is a reticulocyte count different from a red blood cell count?
A red blood cell count measures mature red blood cells, while this test measures reticulocytes, the younger cells still being produced, reflecting the production process itself.
Can I get the Reticulocyte Count, Automated test without a doctor's visit or insurance?
Yes. The $39 cash price includes an independent physician's order, so no referral is needed, and insurance is never involved.
