How do you interpret the red cell indices?
The indices include: Average red blood cell size (MCV)…These test results indicate the type of anemia:
- MCV below normal. Microcytic anemia (may be due to low iron levels, lead poisoning, or thalassemia).
- MCV normal.
- MCV above normal.
- MCH below normal.
- MCH normal.
- MCH above normal.
What are the 3 red blood cell indices?
The indices include: Average red blood cell size (MCV) Hemoglobin amount per red blood cell (MCH) The amount of hemoglobin relative to the size of the cell (hemoglobin concentration) per red blood cell (MCHC)
What is normal RBC indices?
According to the American Association for Clinical Chemistry, normal values for RBC indices are: The MCV should be 80 to 96 femtoliters. The MCH should be 27 to 33 picograms per cell. The MCHC should be 33.4 to 35.5 grams per deciliter.
How are erythrocyte indices calculated?
RBC is per million cells. MCV = Hct × 10/RBC (84-96 fL) •Mean corpuscular Hb (MCH) = Hb × 10/RBC (26-36 pg) •Mean corpuscular Hb concentration (MCHC) = Hb × 10/Hct (32-36%) A rapid method of determining whether cellular indices are normocytic and normochromic is to multiply the RBC and Hb by 3.
What is normal range of MCV and MCH?
Normal Results These test results are in the normal range: MCV: 80 to 100 femtoliter. MCH: 27 to 31 picograms/cell.
What is MCH MCV and MCHC?
Definition. Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were first introduced by Wintrobe in 1929 to define the size (MCV) and hemoglobin content (MCH, MCHC) of red blood cells.
What does high RBC and low MCV mean?
A high RBC count combined with a low mean volume generally is attributed to thalassemia minor, either alpha or beta, or to polycythemia vera with iron deficiency. Among 330 patients with a mean corpuscular volume (MCV) less than 70 cumu, 35 had increased RBC counts.
What does low MCV MCH MCHC and high RDW and RBC mean?
a high RDW and typical MCV suggests an iron, B12, or folate deficiency, or possibly chronic liver disease. a high RDW and low MCV suggests iron deficiency or microcytic anemia. a high RDW and high MCV indicates a lack of B12 or folate, macrocytic anemia, or chronic liver disease.
What does a low MCV MCH and MCHC mean?
A low mean corpuscular hemoglobin concentration (MCHC) shows that someone’s red blood cells do not have enough hemoglobin. Hemoglobin is an iron-rich protein, and a lack of it may indicate anemia.
