There is no hematological disorder associated with low RDW level. Conversely, in thalassemia, which is a disorder of globin synthesis, the number of RBCs produced is normal, but the cells are smaller and more fragile.

Patient groups have been evaluated according to RBC, RDW, Mentzer index, Shine and Lal index, England and Fraser index, Srivastava index, Green and King index, RDWI and Ricerca index. Elevated RDW helps provide a clue for a diagnosis of early nutritional deficiency such as iron, folate, or vitamin B12 deficiency as it becomes elevated earlier than other red blood cell parameters. So Iron Deficiency Anemia (IDA) and Thal are the two big microcytic/hypochromic options that you first learn in hematology. In Tunisia, Results: Srivastava Index, mean corpuscular hemoglobin, thalassemia and sickle cell disease represent the most red blood cell, Mentzer Index (MI) and mean corpuscular prevalent monogenic hemoglobin disorders with 2.21% hemoglobin concentration show the highest reliability in and 1.89% of carriers, respectively [1]. Pathological implications Normal RDW. RDW RDW is increased in Iron deficiency anemia. The subjects were students with MCV <80 fl, MCH <27 pq. RDW index was calculated by by multiplying MCV by RDW and divided by RBC. 2. [2], The index is calculated from the results of a complete blood count. Mentzer index; Purpose: in differentiating iron deficiency anemia from beta thalassemia: The index is calculated from the results of a complete blood count. None of these different formulations are superior to RBC value obtained from automated analyzers in adult cases with IDA and beta-TT. I’d make the child 13 to 17 years of age so head circumference would not be a factor, but it’s your choice. Background. thalassemia syndromes are a group of hereditary disorders characterized by a genetic deficiency in the synthesis of beta-globin chains. between IDA and βTT, such as Green and King Index (GKI), RDW Index (RDWI), Srivastava Index (SRI), Mentzer Index (MI), Shine and Lal Index (SLI), Ehsani Index (EI), and Sirdah Index (SI), were evaluated. The population was students who were admitted to the University of Dr. Soetomo who came for complete blood count examination. Mentzer index, England and Fraser, Shine and Lal, Srivastava and Sirdah formulae were investigated. Combination of low MCV and high RDW is one of the best screening test for the Iron deficiency anemia. It has an autosomal recessive pattern of inheritance which can result into homozygous state called beta Thalassemia Major or heterozygous state known as Beta Thalassemia trait. They have a sensitivity of 73.5% and 81.8% and specificity of 94.8% and 95.7% respectively.

The principle involved is as follows: In iron deficiency, the marrow cannot produce as many RBCs and they are small (microcytic), so the RBC count and the MCV will both be low, and as a result, the index will be greater than 13. I'd make the child 13 to 17 years of age so head circumference would not be a factor, but it's your choice. Kesimpulan. METHODS: A retrospective cross-sectional study was performed on 202 subjects.

You would rely on the patient symptoms, and history as well as other labs such as iron testing. A low Mentzer Index, calculated from CBC data [MCV/RBC < 13], may suggest this disorder but a hemoglobin electrophoresis would be diagnostic. Yes Omar. The RDW in thalassemias is usually within or very close to the reference interval, reflecting the uniformity of red cell size (microcytes). 1 0 obj Mentzer index and RDW is a test that is widely used by clinicians to differentiating early screening of Thalassemia with iron deficiency anemia. Mentzer index..? 1% and that of Green and King index was 79.31%. The mean particle size corresponds to the MCV, the distribution width to the RDW, and the average refractive index to the MCHC, as discussed in Friebel and Meinke 48. A number of hematological indices are also useful (Mentzer, … Therefore, on the basis of Mentzer’ index and RDW we can diagnose β … %PDF-1.5 The RDW will be elevated in more than 90 percent of persons with iron deficiency, ...

The RDW/RBC formula proved to be the most reliable index as they had 100.0% specificity and PPV and the highest efficiency (94.58%) and Youden's Index (91.18%), as well as high sensitivity (91.18%) and NPV (87.67%). There is no hematological disorder associated with low RDW level. Conversely, in thalassemia, which is a disorder of globin synthesis, the number of RBCs produced is normal, but the cells are smaller and more fragile.
