High MCV and low MCHC can be caused by many reasons. If your MCV is in between 83 fL and 101 fL and your MCHC is in between 31.5 g/dL and 34.5 g/dL then you need not worry as these are the normal ranges for MCV and MCHC respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body. When it comes to your red blood cells, size matters. Healthy red blood cells are about the same size, ranging from 6.2 to 8.2 micrometers. Having red blood cells that are vastly different sizes from each other (high variation) may be a sign of anemia. Anemia is a condition that involves not having enough healthy red blood cells to supply oxygen ICD-10. ICD-10-CM Codes. Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified. Abnormal findings on examination of blood, without diagnosis. Abnormality of red blood cells (R71) Other abnormality of red blood cells (R71.8) R71.0. R71.8. R73. High MCH and low Platelet count can be caused by many reasons. If your MCH is in between 27 pg and 32 pg and your Platelet count is in between 150 thou/uL and 450 thou/uL then you need not worry as these are the normal ranges for MCH and Platelet count respectively. But if your levels are lesser or greater than the above values, then there may A low MCHC (hypochromia) may mean that there is a lower concentration of hemoglobin within a given volume of red blood cells and, hence, a reduced capacity to carry oxygen to the body's tissues. A high MCHC (hyperchromia) can mean that there is a higher hemoglobin concentration in red blood cells than usual. Know, however, that your MCHC value Anemia is a condition in which your blood has fewer red blood cells than normal. Your red blood cells may also have less hemoglobin than normal. Hemoglobin is the iron-rich protein that allows red blood cells to carry oxygen from your lungs to the rest of your body. Your body needs oxygen to work properly. With fewer red blood cells or less Dr. Louis Cooper answered. Pediatrics 50 years experience. More info needed: high rbc and low mcv maybe normal for you and may represent thalassemia trait which is genetic. Created for people with ongoing healthcare needs but benefits everyone.

The results of RBC indices are used to diagnose different types of anemia. There are several types of anemia, and each type has a different effect on the size, shape, and/or quality of red blood cells. 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. Mean corpuscular hemoglobin, or MCH, is the average amount of hemoglobin in one of your red blood cells. Mean corpuscular hemoglobin (MCH) is part of a complete blood count (CBC) test. MCH is a useful measurement for understanding how effectively oxygen is being distributed throughout the body. Changes in MCH or other RBC indices may be a sign LV1cps.
