High MCH Levels
Having an MCH level above 31 picograms/cell is most commonly associated with the following conditions: Certain types of kidney diseases, including kidney cancer. Congenital heart defect. Lung disease, including chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis4.
Should I be concerned if my MCH is high?
MCH levels over 34 pg are generally considered abnormally high. The most common reason for high MCH is macrocytic anemia, which is a blood disorder in which the body fails to produce enough red blood cells.
What are symptoms of high MCH?
If you have a high MCH value, you may experience the following symptoms:
shortness of breath.chest pain.fast heartbeat.fatigue or weakness.very pale or yellowish skin.headache.
How serious is Macrocytosis?
Macrocytosis is usually mild to moderate but can become severe. It can be due to a manageable cause (such as a vegan diet, which can be treated with supplements)3 or be due to a serious illness, such as liver disease or cancer.
Why is my MCV high?
High MCV means that red blood cells are too large and indicates macrocytic anemia. This condition can be caused by several factors including low folate or vitamin B12 levels or chemotherapy.
How do you treat high MCV?
Add more red meat and chicken to your diet to increase your vitamin B-12 intake. If you’re a vegetarian or vegan, you can add beans and dark, leafy greens for folate. Try fortified breakfast cereals for vitamin B-12. Reduce the amount of alcohol you drink.
What diet causes macrocytic anemia?
A folate deficiency, sometimes known as vitamin B-9 deficiency, can also cause macrocytic anemia. Pregnant and breast-feeding women use more folate and have a higher risk of becoming deficient. People who do not eat enough folate-rich foods can also become deficient.
Is having large red blood cells serious?
Macrocytosis is a condition in which your red blood cells are larger than they should be. While it isn’t a condition of its own, macrocytosis is a sign that you have an underlying health condition and may lead to a severe form of anemia called macrocytic normochromic anemia.
What diseases cause large red blood cells?

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.
What medications cause high MCV?
Which drugs cause macrocytosis?
Folate antagonists (eg, methotrexate )Purine antagonists (eg, 6-mercaptopurine [6-MP])Pyrimidine antagonists (eg, cytosine arabinoside [ara-C])Alkylating agents (eg, cyclophosphamide)Tyrosine kinase inhibitors (eg, sunitinib, and imatinib)Zidovudine (AZT)Trimethoprim.
Is high MCV serious?
Researchers have found that patients with kidney disease and high MCV levels were at greater risk of death. They are over 3.5 times more likely to suffer from heart disease than those who had a normal MCV.
What is a MCH blood test used for?
The purpose of a mean corpuscular hemoglobin (MCH) test is to calculate the amount of hemoglobin in an individual red blood cell. The MCH test is one of several tests that are used to diagnose and classify different types of anemia.
What is MCH normal range?
Normal MCH levels
Laboratories measure MCH in picograms (pg) per cell. The normal range of MCH values are between 27 and 31 pg per cell. Individuals with certain health conditions may have MCH levels that are lower or higher than average. The table below shows what the different MCH levels could indicate.
