What does elevated mch mean?

Elevated mean corpuscular hemoglobin (MCH) indicates that the average amount of hemoglobin per red blood cell is higher than normal. This can be associated with conditions such as macrocytic anemia, where red blood cells are larger than usual, often due to vitamin B12 or folate deficiency. Other potential causes include liver disease and hypothyroidism. It's important to interpret elevated MCH levels in conjunction with other blood test results for an accurate diagnosis.
