What are RBC indices Slideshare?
MEAN CELL HEMOGLOBIN CONCENTRATION It is the average concentration of hemoglobin in a deciliter of erythrocytes and expressed in g/dl It is the ratio of hemoglobin mass to volume in which it is contained MCHC = Hb (g/dl) x 100 Hct (L/L) Normochromic: 32-36g/dl Hypochromic: <32g/dl Hyperchromic: >36g/dl.
What are RBC indices used for?
Red blood cell (RBC) indices are part of a complete blood count, a group of tests that measures various parts and features of your blood. The results of RBC indices are used to diagnose different types of anemia.
How are red blood cell RBC cellular 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 hematocrit PPT?
What is hematocrit (Hct)? • The volume of the red cells per unite volume of blood. Or • The percentage volume of red cells in a volume of whole blood. • Also called ”packed cell volume” (PCV).
What is MCV in RBC indices?
MCV stands for mean corpuscular volume. An MCV blood test measures the average size of your red blood cells. Red blood cells carry oxygen from your lungs to every cell in your body. Your cells need oxygen to grow, reproduce, and stay healthy.
What is PCV in RBC indices?
The packed cell volume (PCV) is a measurement of the proportion of blood that is made up of cells. The value is expressed as a percentage or fraction of cells in blood. For example, a PCV of 40% means that there are 40 millilitres of cells in 100 millilitres of blood.
How do you interpret blood 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 level of RBC indicates anemia?
Normal levels of RBCs and hemoglobin vary for men, women and children. They also vary from laboratory to laboratory. An adult has anemia, or is considered anemic, when their hemoglobin level falls to about 100g/L or less.
What is PCV estimation?
The packed cell volume (PCV) is the measure of the ratio of the volume occupied by the red cells to the volume of whole blood in a sample of capillary, venous, or arterial blood. The ratio is measured after appropriate centrifugation6,10 and is expressed as a decimal fraction.
What are MCV MCH 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 is PCV MCV and MCH?
Your MCH value is related to two other values, mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC). Together, MCH, MCV, and MCHC are sometimes referred to as red blood cell indices. MCV is a measurement of the average size of your red blood cells. MCH results tend to mirror MCV results.

How do you assess RBC?
The RBC count is almost always part of a complete blood count (CBC) test. The test can help diagnose different kinds of anemia (low number of RBCs) and other conditions affecting red blood cells. Other conditions that may require an RBC count are: Disease that damages kidney blood vessels (Alport syndrome)
