Ed Reschke / Getty Images What Are the Symptoms of Macrocytosis? Generally, macrocytosis is associated with anemia (macrocytic anemia), which is diminished RBC count. The condition causes a decrease in oxygen delivered to the body’s tissues. Usually, the symptoms are mild to moderate, but sometimes the effects can be severe. • Diarrhea, which can be a sign of malabsorption, can make you deficient in vitamin B12 and other nutrients • Enlarged tongue (glossitis) can develop due to vitamin B12 deficiency • Peripheral neuropathy causes numbness of the fingers and toes and can result from a vitamin B12 deficiency or alcoholism • Weakness can develop from an iron deficiency • Bruising or bleeding can occur due to leukemia, cancer of the blood and bone marrow • Enlarged abdomen due to splenomegaly (enlarged • • Mean corpuscular volume (MCV) measures the average size of the RBCs, which is usually greater than 100 femtoliter (fL) in macrocytosis • Red cell distribution width (RDW) measures the variation in size of the RBCs; a normal range for RDW is 11.8%–14.6%, and it is expected to be high in macrocytosis due to the variation in RBC size How Is Macrocytosis Treated? The treatment of macrocytosis centers on correcting the cause when possible. Oftentimes, vitamin B12 and/or folate supplementation will correct the problem. If you cannot absorb vitamin B12 adequately due to gastrointestinal issues, you may need to get B12 injections rather than taking a supplement by mouth. • Chiang ...

Mean corpuscular volume (MCV) measures the red blood cell size. This test is usually part of a complete blood count to analyse different blood components, including platelets and white blood cells. Your doctor may order an MCV test to confirm if you have anaemia. Different levels of MCV can diagnose specific anaemia types. What is MCV in a blood test? (keyword) The red blood cells have several characteristics that doctors can measure with specific indicators. Your doctor can use MCV to indicate the average size and volume of red blood cells. Other indicators from the red blood cells include: • Mean corpuscular haemoglobin (MCH) MCH is the average level of haemoglobin in the red blood cell. • Mean corpuscular haemoglobin concentration (MCHC) MCHC is the average haemoglobin concentration in the red blood cells • Red cell distribution width (RDW) RDW measures the differences in the size of red blood cells These measurements are vital when diagnosing specific types of anaemia and other health issues. What happens during the MCV level blood test? You do not need special preparations for the MCV blood test. The healthcare provider will draw a blood sample from your vein during the test. It may cause slight pain and a stinging sensation. What are the risks? Drawing a blood sample has a few risks, but people differ, so blood collecting may be straightforward and painless for many people. The side effects of the blood collection for an MCV test include: • Cold feet and hands • Unex...
