Red Blood Cell (RBC) Count Test
The Red Blood Cell (RBC) Count Test measures the number of red blood cells in your blood. RBCs, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to the lungs. At Hindustan Laboratory, we provide accurate RBC count testing to help diagnose and monitor conditions affecting oxygen transport and overall health.
What is an RBC Count Test?
An RBC count test determines the concentration of red blood cells in a blood sample. It is typically part of a Complete Blood Count (CBC) but can be ordered separately to evaluate conditions such as anemia, dehydration, or polycythemia. This test helps assess your body’s ability to deliver oxygen effectively.
Purpose of the RBC Count Test
- Diagnose conditions like anemia, polycythemia, or dehydration.
- Monitor chronic conditions affecting RBC production, such as kidney disease or bone marrow disorders.
- Evaluate symptoms like fatigue, weakness, or shortness of breath.
- Monitor treatments that affect RBCs, such as chemotherapy or iron therapy.
- Assess overall health during routine checkups.
RBC Count Reference Range
| Test |
Description |
Normal Range (Approx.) |
| RBC Count |
Measures the number of red blood cells in the blood. |
Men: 4.5–5.9 million cells per microliter (µL)
Women: 4.1–5.1 million cells/µL |
| Hematocrit (Hct) |
Percentage of blood volume made up of RBCs. |
Men: 41–50%
Women: 36–44% |
| Mean Corpuscular Volume (MCV) |
Average size of RBCs, indicating type of anemia. |
80–100 femtoliters (fL) |
Note: Normal ranges may vary slightly depending on laboratory standards. Always consult your doctor for interpretation.
Preparation for the RBC Count Test
Generally, no special preparation is required for an RBC count test. However, consider these guidelines:
- Inform your doctor about medications (e.g., chemotherapy drugs, erythropoietin, or supplements like iron) that may affect RBC counts.
- Notify Hindustan Laboratory of recent conditions like dehydration, high-altitude living, or pregnancy, which can influence results.
- Stay hydrated to ensure an easier blood draw.
- Follow any specific instructions provided by our team, though fasting is typically not required.
Procedure
The RBC count test is a simple and quick blood test:
- A healthcare professional cleans the site (usually your arm) with an antiseptic.
- A needle is inserted into a vein to collect a small blood sample.
- The sample is sent to our advanced laboratory for analysis, where RBCs are counted using automated analyzers.
- The procedure takes less than 5 minutes and involves minimal discomfort.
Interpreting RBC Count Results
Your RBC count results are compared to standard reference ranges. Abnormal results may indicate:
- Low RBC Count (Anemia):
- Causes: Iron deficiency, vitamin B12/folate deficiency, chronic diseases (e.g., kidney disease), blood loss, or bone marrow disorders.
- Symptoms: Fatigue, weakness, pale skin, shortness of breath.
- High RBC Count (Polycythemia):
- Causes: Dehydration, smoking, high-altitude living, lung disease, or bone marrow disorders (e.g., polycythemia vera).
- Symptoms: Headaches, dizziness, red skin, or increased risk of blood clots.
- Abnormal MCV:
- High MCV: Macrocytic anemia (e.g., B12 deficiency).
- Low MCV: Microcytic anemia (e.g., iron deficiency).
Always consult your doctor for a detailed interpretation, as results depend on your medical history, symptoms, and other test findings (e.g., hemoglobin, hematocrit).
