What is the MCV Meaning in A Blood Test?

Blood comprises white blood cells (WBCs), red blood cells (RBCs), and platelets. Each acts as a shield for your body. 

WBCs fight off infections, while RBCs' normal functioning ensures normal health conditions. 

In a blood test, MCV stands for mean corpuscular volume, whose low and high values indicate an abnormal health condition. 

Today, let’s understand everything MCV means in a blood test. 

MCV Meaning in a Blood Test

MCV, meaning MCV in a blood test, measures the size of your red blood cells (RBC). RBCs are necessary for proper functioning as they carry oxygen throughout the body. 

MCV's meaning in a blood test and its role are important to understand as they help assess general health. RCB includes four indices: MCV, MCH, MCHC, and RDW. Here is what they represent. 

1. MCV- Mean Corpuscular Volume is the average size of your red blood cells. 
2. MCH- Mean Corpuscular Hemoglobin is the average amount of hemoglobin in your RBCs. 
3. MCHC- Mean Corpuscular Hemoglobin Concentration is the average amount of hemoglobin concentration in your RBCs. 
4. RDW- Red Cell Distribution Width shows the varied size of your red blood cells.

A low MCV means iron deficiency or anemia, whereas a high MCV means vitamin deficiency or liver disease. 

MCV is part of the complete blood count (CBC) test, a routine blood test that measures blood components and diagnoses various disorders. 

It is important to measure the size of red blood cells promptly to prevent the risk of severe health complications.

13 Signs You Need An MCV Blood Test

MCV blood tests are part of routine screening; however, several signs clearly indicate that you need one. 

1. Dizziness 
2. Pale Skin 
3. Headaches 
4. Hair Loss
5. Chronic Fatigue 
6. Lethargy 
7. Chest Pain
8. Pagophagia (craving for eating ice, paper, or chalk) 
9. Brittle nails 
10. Sore tongue 
11. Rapid heartbeats 
12. Pounding or whooshing sound in the ears 
13. Headaches 

If you see these signs, it is better to seek medical consultation. Timely monitoring and management can help prevent serious health issues.

When is an MCV Blood Test Performed?

Your doctor may also recommend an MCV blood test if you have jaundice or signs of anemia. 

The MCV blood test is a routine test conducted during a complete blood count (CBC). A low MCV test indicates anemia or iron deficiency, while a high MCV test indicates liver disease or vitamin B12 (folate) deficiency. 

MCV means that a blood test checks the size of red blood cells and prevents health complications. Moreover, it requires no special preparation and has no major risks. 

However, the test requires drawing blood from a syringe needle, which can cause skin infection, excessive bleeding, bruising, or weakness.

What is the MCV Blood Test Normal Range? 

The normal MCV range differs based on gender and age. Each age group experiences a different range. Proven scientific studies show that the MCV levels change in healthy males and females as they age. 

Here is a breakdown of MCV's normal range according to age and gender. 

fl- Femtoliters

Age	Male in fl	Female in fl
Below 10	81.9	82.4
10 to 19	87.3	87.6
20 to 29	89.8	90.0
30 to 39	90.4	90.4
40 to 49	91.3	91.0
50 to 59	92.0	91.1
60 to 69	92.5	91.6
70 to 79	93.0	92.1
80 to 89	93.6	92.5

5 Reasons for MCV Blood Test Low Range

A low MCV means the size of your RBC is under the MCV normal range. Experts term this as microcytosis, which indicates certain medical conditions, including: 

• Sideroblastic Anemia

It is a rare blood disorder that occurs when the bone marrow produces abnormal red blood cells instead of healthy red blood cells. 

Symptoms of sideroblastic anemia are: 

• Weakness 
• Fatigue 
• Headaches
• Swollen spleen or liver 
• Difficulty breathing
• Heart Palpitations 

Health Tip: Take vitamin B6 supplements to curb medical problems such as liver damage and heart disease. 

• Thalassemia 

Thalassemia is a blood disorder that prevents the production of hemoglobin. It can be inherited from one or both parents. 

Thalassemia anemia can be mild or severe, depending on the number of affected genes. You can develop either alpha thalassemia or beta thalassemia. 

Symptoms of thalassemia include: 

• Dizziness or tiredness 
• Weakness 
• Rapid heartbeat 
• Headaches 
• Leg cramps 
• Pale skin 
• Concentration issues 
• Shortness of breath 
• Difficulty breathing 

• Iron-deficiency Anemia 

Iron deficiency anemia is the most common type of anemia. It occurs when the body doesn’t produce enough iron, affecting the production of healthy red blood cells. Low MCV levels contribute to iron-deficiency anemia. Timely monitoring can help cure anemia and deal with serious health issues. 

Symptoms of iron-deficiency anemia 

• Hair loss 
• Brittle nails
• Pale or yellow skin 
• Shortness of breath 
• Chest pain 
• Pounding in the ear 
• Craving for ice, paper, or clay
• Sore or smooth tongue 
• A rapid or fast heartbeat. 

Add iron-rich foods and iron supplements to replenish iron levels in the body. 

• Lead Poisoning 

Lead poisoning is a serious health issue that can occur because of low MCV levels or chronic lead exposure. This cause leads to a reduction in the amount and size of red blood cells. 

Symptoms of Lead Poisoning include: 

• Headache 
• Abdominal pain 
• Pregnancy complications 
• Miscarriage or premature birth 
• Mood disorders
• Reduced sperm count and abnormal sperm 
• Concentration issues 
• Memory loss 
• High blood pressure 
• Joint and muscle pain 

Add food high in iron, calcium, and vitamin C to remove lead from your body naturally. Also, add CBC tests to your routine screening tests to monitor lead formation and prevent serious health issues. You can book it from Redcliffe Labs at just INR 299. 

• Spherocytosis 

Anemia or iron deficiency can contribute to spherocytosis. It is a hereditary or genetic blood disorder that affects the size of red blood cells and makes it difficult to move through blood vessels. 

Symptoms of Spherocytosis include 

• Jaundice 
• Stomach pain 
• Chronic fatigue 
• Loss of appetite 
• Irritability 
• Pale skin 
• Shortness of breath 

12 Reason for MCV Blood Test High Range

A high MCV means the size and number of red blood cells are greater than the normal range. This can be caused by low blood flow or increased destruction of red blood cells. Doctors term this condition hemolysis.

The bone marrow in your body instantly responds by churning out larger red blood cells, a process usually termed macrocytosis. 

Macrocytosis can occur because of vitamin B12 and B9 deficiencies. It prevents immature red blood cells from maturing, which later turns into macrocytic anemia. 

Primary reasons for high MCV or macrocytosis include: 

1. Smoking 
2. Chemotherapy 
3. Myelodysplastic syndrome 
4. Chronic hypoxia or low blood oxygen levels 
5. Carbon monoxide poisoning 
6. Hypothyroidism 
7. Diabetes 
8. Liver disease 
9. Folate deficiency 
10. Vitamin B12 deficiency 
11. Certain Cancers like liver, esophageal, and colorectal cancer
12. Alcohol use disorder 

People following a vegan diet or having autoimmune gastritis are at high risk of vitamin B12 deficiency or high MCV levels. 

The Final Though 

The above information covers MCV meaning in a blood test. MCV simply helps evaluate the size of red blood cells. A low MCV blood test indicates iron deficiency, while a high test indicates vitamin B12 deficiency. If you see any symptoms of anemia, consult a doctor and prevent the risk of chronic diseases. Book the Complete Blood Count (CBC) test from Redcliffe Labs and keep a check on the functioning of your red blood cells.
