Anemia is a common condition that could be affecting you without you even realizing it. If you’ve been feeling unusually tired, weak, or generally low on energy, there’s a chance your red blood cells might not be doing their job properly.
One of the most important tools your doctor can use to figure out what’s going on is something called an mcv blood test.
This test helps your doctor learn more about your red blood cells—specifically, their size—which plays a big role in identifying the type of anemia you may have.
In this guide, we’ll walk you through what the MCV test is, why it’s done, what your results mean, and how you can use this information to take better control of your health.
Whether your doctor has already ordered the test or you’re just curious, you’ll find everything you need to know right here. Let’s get started.
What is an MCV blood test?
MCV stands for mean corpuscular volume. It measures the average size of your red blood cells. The MCV blood test is part of a complete blood count (CBC), which checks the overall health of your blood.
This test helps doctors see if your red blood cells are:
- Too small (microcytic)
- Normal-sized (normocytic)
- Too large (macrocytic)
Knowing the size of your red blood cells helps your doctor figure out what kind of anemia you may have and what is causing it.
What is MCV test used for?
The MCV test is mainly used to diagnose and classify anemia. Based on the MCV blood test normal range, which is generally between 80 and 100 femtolitres (fL), anemia can be grouped as:
- Microcytic anemia (low MCV)—Red blood cells are smaller than normal.
- Normocytic anemia – Red blood cells are normal in size.
- Macrocytic anemia (high MCV)—Red blood cells are larger than normal.
These types of anemia may be caused by:
- Iron deficiency
- Vitamin B12 or folate deficiency
- Chronic diseases
- Bone marrow disorders
- Genetic conditions like thalassemia
Why do I need an MCV blood test?
Your doctor might suggest an MCV test if you have symptoms of anemia, such as:
- Feeling tired all the time
- Pale skin or gums
- Shortness of breath
- Feeling dizzy or light-headed
- Cold hands and feet
- Irregular heartbeat
The MCV test may also be done during regular health checkups, especially if you have a family history of anemia or are at risk due to diet, health conditions, or medications.
What happens during an MCV blood test?
This test is very simple and quick:
- A healthcare worker cleans the area on your arm.
- A needle is used to take a small amount of blood.
- The blood is collected in a tube and sent to a lab.
Most people only feel a small pinch, and the whole process takes just a few minutes.
How do I prepare for MCV blood test?
Usually, you don’t need to do anything special to get ready for the MCV test. But if other tests are being done at the same time, your doctor may ask you to fast (not eat or drink) for a few hours. Always follow your doctor’s instructions.
What are the risks associated with MCV test?
The test is very safe. Some minor side effects may include:
- A little pain or bruising where the needle was used
- Light bleeding
- Feeling dizzy (rarely)
These effects go away quickly.
What do the MCV results mean?
The MCV blood test normal range is about 80–100 fL. Here’s what your results might mean:
- Low MCV (below 80 fL): You may have microcytic anemia. This often means iron deficiency or a condition like thalassemia. In simple terms, your red blood cells are smaller than they should be. In simple terms, low MCV means your body might not be getting enough iron.
- Normal MCV (80–100 fL): You may still have anemia, but your red blood cells are the right size. This is called normocytic anemia and might be linked to chronic diseases or sudden blood loss.
- High MCV (above 100 fL): You may have macrocytic anemia. This could mean a vitamin B12 or folate deficiency. In this case, your red blood cells are bigger than usual.
Doctors also look at other parts of your blood test, like
- Hemoglobin
- Hematocrit
- RDW (Red Cell Distribution Width)
- MCH (Mean Corpuscular Hemoglobin)
These values help your doctor understand the complete picture and decide on treatment.
Frequently Asked Questions
What is MCV in a blood test?
MCV (Mean Corpuscular Volume) measures the average size of your red blood cells. It helps doctors find out what type of anemia you might have.
What are MCV and MCH?
MCV shows the size of red blood cells, while MCH (mean corpuscular haemoglobin) tells how much hemoglobin is in each red blood cell. Both are used to check for different types of anemia.
How to Lower MCV Level?
If your MCV is too high (macrocytic anemia), your doctor may check for and treat vitamin B12 or folate deficiency. Eating foods rich in B12 (like eggs, dairy, and fish) or taking supplements may help.
How to Increase MCV in Blood?
If your MCV is too low (microcytic anemia), it often means you need more iron. Eating iron-rich foods like leafy greens, beans, and red meat, or taking iron supplements, can help increase your MCV level.
What is the cost of MCV blood test?
The cost of an MCV, or mean corpuscular volume blood test, in India is generally quite affordable and can range anywhere from ₹50 to ₹400 depending on the city, diagnostic centre, and whether home sample collection is included. It’s a part of the complete blood count (CBC) test, so it may also be bundled with other tests. To get the most accurate pricing, it’s best to check with nearby diagnostic labs or online health platforms offering lab services.
When to Speak with a Doctor?
If your MCV test result is not in the normal range, talk to your doctor. It doesn’t always mean something serious, but more tests may be needed to find the exact cause and proper treatment.
Conclusion
The MCV blood test is an important part of understanding anemia. It helps identify if your red blood cells are the right size and gives clues about what’s causing your anemia.
Knowing your anemia MCV levels and how they relate to your symptoms can help you and your doctor take better care of your health. Always follow your doctor’s advice for diagnosis and treatment based on your test results.
