In 1973 William C Mentzer described a facile way to differentiate between mild microcytic anemia due to beta-thalassemia carrier state and microcytic anemia due to iron deficiency starting from commonly used blood laboratory tests by dividing the mean corpuscular volume MCV to the red blood cell RBC count.
The Mentzer index at a higher cut-off of 14 may be suitable for Indians. MDCalc loves calculator creators researchers who through intelligent and often complex methods discover tools that describe scientific facts that can then be applied in practice. These are real.
The index is calculated from the results of a complete blood count. According to our data the Mentzer index had the highest Youdens index for correctly distinguishing β -TT and IDA at 81. This index utilized red cell volume and count.
The corrected Mentzer index calculations showed a prevalence of 59 and 32 among IDA and thalassemia infants respectively. The only 2 input parameters include Mean corpuscular volume MCV and Red Blood cell. Background and aims Iron deficiency anaemia IDA and thalassemia are the most common microcytic anaemia in children.
Mentzer index calculator can give a fair idea of diagnosis on the basis of a simple complete blood count report. The Absolute Reticulocyte Count Reticulocyte Index Assesses appropriate response to anemia frequently in Sickle Cell Disease patients. Sometimes expensive or invasive investigations are necessary for their distinction.
If the quotient of the mean corpuscular volume MCV in fL divided by the red blood cell count RBC. 33rd European Pediatrics Conference. The aim of our study was to evaluate the reliability of Mentzer index in the differentiation of iron deficiency anemia and Thalassemia trait.
If the quotient of the mean corpuscular volume MCV in fL divided by the red blood cell count RBC in Millions per microLiter is less than 13 thalassemia is said to be more likely. Mentzer is said to be helpful in differentiating iron deficiency anemia from beta thalassemia. The England and Fraser and the Shine and Lal indices had the lowest Youdens index values of 514 and 102 respectively.
Mentzer Index For Thalassemia Medical Calculator thalassemia syndromes are a group of hereditary disorders characterized by a genetic deficiency in the synthesis of beta-globin chains. In practice most paediatricians use Mentzer index maybe out of. Only those patients who have been found to be having iron.
5th International Conference on Advances in Neonatal and Pediatric Nutrition. The index higher than 13 indicates an iron deficiency while thalassemia causes this index to be lower than 13. In the homozygous state beta thalassemia ie thalassemia major causes severe transfusion-dependent anemia.
Mentzer index could be used to predict the diagnosis of beta-thalassemia carrier. Calculation of the Mentzer index mean corpuscular volume per red cell count may be helpful. Mentzer index OR value was 24 05 - 115 CI95.
If the result is greater than 14 then iron-deficiency anemia is more likely. Mentzer Index diagnostic value thalassemia. The index is calculated from the results of a complete blood count.
A Mentzer index of less than 13 suggests that the patient has the thalassemia trait and an index of. Mentzer index OR value was 24 05 - 115 CI95. Equation for calculate mentzer index is Mentzer index MCV RBC.
211 had mild anemia 76 had moderate anemia while 02 had severe anemia. This calculator calculates the mentzer index using mcv mean corpuscular volume red blood cell values. To calculate Mentzer index divide MCV by RBC.
When the Mentzer index was calculated 91 of children with microcytic anemia were correctly diagnosed. If the result is greater than 13 then iron-deficiency anemia is said to be more likely. For children the Mentzer index MCVred blood cell count can help distinguish between iron deficiency and thalassemia.
The original study observed a sensitivity of 8974 and a specificity of 8696 with a cut-off of. Index MCV RBC where MCV is the mean corpuscular volume given in femtoliters and RBC is the red blood cell count in a million per mm³. A number of haematological indices are useful but some of them assume difficult calculation.
