These tests include: Red blood count: The count of all red blood cells in a volume of blood. Adult women: 3.9-5.0 million cells/µL. Adult men: 4.3-5.7 million cells/µL. Please refer to previous posts for detailed discussion of causes of low and high RBC. Hemoglobin (Hb): The amount of hemoglobin in a volume of blood.
Normal is 82 to 99 femtoliters. Mean corpuscular hemoglobin (MCH) measures the amount of hemoglobin in an average cell. Normal is 25 to 35 picograms. Mean corpuscular hemoglobin concentration (MCHC) measures the concentration of hemoglobin in red blood cells. Normal is 32% to 36%.

High Hematocrit and low MCHC can be caused by a lot of reasons. If you take Hematocrit and MCHC blood tests and the results are higher than 50 % for Hematocrit and lower than 31.5 g/dL for MCHC, your physician may recommend more tests to figure out the problem. You might also get these tests if your physician thinks you have some other disease.
Anemia and Red Blood Cell Disorders. Randy Hurley, in Immigrant Medicine, 2007. Microcytic anemia (MCV < 80 fl) The differential diagnosis of microcytosis can be assessed by history, physical examination, and laboratory parameters: a severe ‘chronic illness’ should be evident in anemia of chronic disease causing microcytosis as should a source of blood loss for microcytic anemia due to

Anemia can be defined as a reduction in hemoglobin (less than 13.5 g/dL in men; less than 12.0 g/dL in women) or hematocrit (less than 41.0% in men; less than 36.0% in women) or red blood cell (RBC) count. The terms hemoglobin and hematocrit are more commonly used than RBC count in day-to-day clinical practice.
This study which was conducted on a total of 6993 patients with low serum ferritin, 4370 females and 2623 males, HWA found in 130 (0.018%) of the cases. It was 80 (62%) cases in female and 50 (38%) cases in male patients. HWA is a hypoferritinemia with normal reference range of RBC, Hb, Hct, MCV, and MCH, or even Hb could be high [Table 2].
Anemia is a decrease in the number of red blood cells (RBCs) as measured by the red cell count, the hematocrit, or the red cell hemoglobin content. In men, anemia is defined as any of the following: Hemoglobin < 14 g/dL (140 g/L) Hematocrit < 42% (< 0.42) RBC < 4.5 million/mcL (< 4.5 × 10 12 /L)
One common method distinguishes anemias according to cell size (mean corpuscular volume, MCV) and/or amount of intracellular hemoglobin (mean corpuscular hemoglobin, MCH). Common conditions
Background Methotrexate (MTX) is well known to affect folic acid metabolism, so MTX treatment can result in alterations of mean corpuscular volume (MCV), which may impact on red cell distribution width (RDW), as MCV levels feed into RDW calculation. We thus questioned whether RDW levels and subsequently its diagnostic utility in RA subjects, as reported before, are influenced by ongoing MTX
