What is MCV in Blood Test? It is a daily occurrence for us to undergo several laboratory exams when we choose to see our doctor to check our health. These tests are necessary for us to make sure that our organs and bodily functions are working properly. It would also help us in identifying any abnormalities that we would never know unless these tests are taken. The tests, therefore, would help us see if treatment is needed. One of the tests that we take is a blood test. This test is called as mean corpuscular volume, also known as mean cell volume. This test would indicate the blood count, and the let us know the size of the red blood cells produced by the blood. Our blood is one of the most important components of our body. It contains white blood cells which serve as our antibodies for infections and injuries and the red blood cells which contain hemoglobin, an essential component, for the oxygen in our lungs to be delivered without any glitch. Red blood cells, in particular, should be balanced and produced on the reasonable number. What Does An Abnormal MCV Level Mean? It is essential to remember that the level of red blood cells should be standard and just right to perform its function correctly. MCV levels would also let you determine if the patient is anemic or not. But aside from that, it would also let you interpret the reason for the abnormal red blood cells count and how to proceed with the treatment. There are two abnormalities seen in an MCV blood test. The cou...

Causes of High MCHC Depending on the kind you have, anemia may cause high MCHC. Hemolytic anemia may lead to an MCHC measurement above the normal range. Hemolytic anemia develops when red blood cells break down faster than they can be replaced. This type of anemia can happen for a number of reasons, including: Editor’s Note: Even if your MCHC is within a normal range, it is still possible to have a certain type of anemia. With normocytic normochromic anemia, the circulating red blood cells are the same size (normocytic) and have a normal red color (normochromic). This type of anemia can develop for multiple reasons, including acute blood loss and kidney disease. What to Expect When Taking an MCHC Blood Test A healthcare provider will perform an MCHC blood test by drawing blood as part of a CBC. No preparation is needed prior to a CBC. However, if your healthcare provider has ordered other tests in addition to a CBC, you may need to fast for several hours before that test. Your provider will let you know if there are any special instructions to follow. Anemia is usually what’s associated with abnormal MCHC levels. If a healthcare provider determines that anemia is the cause of your low or high MCHC levels, they will want to figure out what is causing the anemia and treat that cause. Treatments for anemia and the conditions that cause it may include: Editor’s Note: Low levels of MCHC have been shown to be associated with poorer outcomes among people hospitalized with acute h...

Low mean corpuscular hemoglobin concentration (MCHC) usually indicates anemia. Other, more serious causes like cancer are rare. MCHC is the average concentration of hemoglobin in your red blood cells. Hemoglobin is the protein molecule that allows red blood cells to carry oxygen to tissues within your body. Your MCHC can fall into low, normal, and high ranges, even if your red blood cell count is normal. The most common cause of low MCHC is anemia. Hypochromic microcytic anemia commonly results in low MCHC. This condition means your red blood cells are smaller than usual and have a decreased level of hemoglobin. This type of • lack of iron • the inability of your body to absorb iron, which can be caused by conditions like celiac disease, Crohn’s disease, and gastric bypass surgery • chronic low-grade blood loss over time from a long menstrual cycle or • In rarer cases, low MCHC and hypochromic microcytic anemia can be caused by: • • parasitic infections like • If your doctor suspects that you have a low MCHC, they may order several blood tests, including: • a blood test that will examine your MCHC levels • a mean corpuscular volume (MCV) test, which measures the average volume of your red blood cells These tests may be included in a Through the results of the tests they order, your doctor should be able to determine exactly what type of anemia you have, making it easier to find the underlying cause. This can help them create a course of treatment. Iron levels Your doctor m...

Macrocytosis is a term used to describe red blood cells that are larger than normal. Also known as megalocytosis or macrocythemia, this condition typically causes no signs or symptoms and is usually detected incidentally on routine blood tests. Macrocytosis isn't a specific disease, but it may indicate an underlying problem that requires medical evaluation. Common causes of macrocytosis include: • Vitamin B-12 deficiency • Folate deficiency • Liver disease • Alcoholism • Hypothyroidism • A side effect of certain medications, such as those used to treat cancer, seizures and autoimmune disorders • Increased red blood cell production by the bone marrow to correct anemia, for example, after blood loss • An underlying bone marrow cancer called myelodysplastic syndrome If you have macrocytosis, blood tests can help determine its cause. In some cases, it may be necessary to remove a sample of your bone marrow — the spongy tissue inside your bones — for testing. Management of macrocytosis consists of finding and treating the underlying cause. In the case of vitamin B-12 or folate deficiency, treatment may include diet modification and dietary supplements or injections. If the underlying cause is resulting in severe anemia, you might need a blood transfusion.

• Post-transfusion: The MCV offers little value if a person has had a • Mixed anemias: If a person has more than one type of anemia, the MCV will be less helpful. For example, if a person has both severe iron deficiency anemia and severe • False positives: In certain settings, the MCV may be falsely high. This can occur when red blood cells clot. Sometimes this happens with agglutinin disease, paraproteinemias, Complementary Tests The MCV is not used alone. Rather, it is read along with other tests performed in a CBC. For example, using MCV alone may result in a misdiagnosis of thalassemia, a condition that causes red blood cells to be destroyed, instead of iron deficiency anemia. This can happen because both have a low MCV. • Red blood cell count: The red blood cell count (RBC) is the number of red blood cells in a blood sample. • Hemoglobin and/or hematocrit: • Mean corpuscular hemoglobin concentration (MCHC): MCHC is the average concentration of hemoglobin contained in a red blood cell. • Red cell distribution width (RDW): If you have recently had a blood transfusion, have mixed anemias, or have a condition where red blood cells clot, MCV may not be accurate. For a complete picture, your healthcare provider will also look at other measurements in a CBC. What To Expect Getting blood drawn is pretty straightforward. There is little risk associated with checking a CBC and MCV. However, there is a small risk of bleeding, bruising, or infection due to the blood draw. • Bleed...

Test Quick Guide Mean corpuscular volume (MCV) is a measurement of the average size of red blood cells (RBC) in a sample of blood. RBC carry oxygen throughout the body to support the health and function of organs and tissues. An MCV test is part of a panel of tests called the RBC indices that evaluate certain features of how RBCs function. The MCV test can help to identify if RBC are too big or too small. Changes in RBC volume can affect how oxygen is distributed throughout the body and may be a sign of a blood disorder or other health conditions. About the Test Purpose of the test The purpose of the MCV test is to measure the average size of your RBC and check for signs of medical conditions such as An MCV test is performed along with several other measurements called RBC indices. These provide information about the physical features of RBC and are included as part of a complete blood count (CBC), a routine blood test. The RBC indices include: • Mean corpuscular volume (MCV) • Mean corpuscular hemoglobin (MCH) • Mean corpuscular hemoglobin concentration (MCHC) • Red cell distribution width (RDW) During an analysis of CBC, MCV may be compared to other RBC indices to diagnose different types of anemia, a condition in which blood does not carry enough oxygen to the body. For more information about the purposes of a CBC, see our guide to the What does the test measure? The MCV test measures the average size of your RBC. RBC can vary from normal in size to abnormally small or ...

A high MCV means your red blood cells are larger than normal. While a high MCV can be associated with a group of cancers called myelodysplastic syndromes, other causes of high MCV, such as vitamin deficiency or liver disease, are far more common. A measurement of mean corpuscular volume (MCV) is included in a Having a high MCV means your red blood cells are larger than typical red blood cells. While a high MCV has many common causes, it can also be a sign of In this article, we take a closer look at MCV, its association with cancer, and the health conditions that more commonly cause high MCV. An MCV test measures the average size of your It’s most likely that you’ll have an MCV test as a part of a CBC that’s done during a The • Normal: The normal range for MCV is 80 to 100 femtoliter (fL). This means your RBCs are a typical size. RBCs that fall into this range are called normocytic. • Low: A low value for MCV is anything under 80 fL. This means your RBCs are smaller than normal. The term for this is microcytic. • High: A high MCV value is anything over 100 fL. Having a high MCV means your RBCs are larger than normal. The term for this is macrocytic. MDS happens when immature blood cells in the Since MDS affects the blood cells of the bone marrow, the RBCs, white blood cells, and platelets can all be affected. RBCs are one cell type that can be involved in MDS. Cells impacted by MDS can have When MDS affects RBCs, it can lead to anemia. In fact, anemia is the Several other ...

Overview What are blood tests? Blood tests are common medical tests. You may have a blood test as part of a routine There are many different blood tests. Some tests focus on your blood cells and platelets. Some evaluate substances in your blood such as electrolytes, proteins and hormones. Others measure certain minerals in your blood. Regardless of why you’re having a blood test, it’s important to remember that blood tests help healthcare providers diagnose health issues. But blood test results aren’t diagnoses. An abnormal blood test result may not mean you have a serious medical condition. When would I need to have a blood test? Your blood plays a big role in your overall health and contains a lot of information about what may be going on in your body. That’s one reason why blood tests are a common medical test. A healthcare provider may do a blood test because: • It’s time for your regular physical. During a checkup, your provider may order blood tests to check on your overall health. They may order a blood test that evaluates many parts of your blood, such as a • Your provider recommends screening tests. Screening tests are done before you have any symptoms. They may recommend screening tests if you’re at risk of developing certain conditions, such as • You don’t feel well. If you have specific symptoms, your provider may order blood tests to determine what’s causing them. For example, if you have symptoms that may be signs you’re pregnant, your provider will do a • Yo...
