In torrid world countries where you cannot afford to get all the relevant investigations Mentzer indie helps a lot in deciding whether it is iron deficiency anemia (index .13) and thalassemia (index <13). index > RDWI > Srivastava index > Green and King Mentzer index..? <> The Mentzer index which is defined as mean corpuscular volume per red cell count. 2. Prof. Dr. Hj. None of these different formulations are superior to RBC value obtained from automated analyzers in adult cases with IDA and beta-TT. If the result is greater than 13, then iron-deficiency anemia is said to be more likely.[3]. These indices were applied on 47 patients with βTT and on 289 patients with IDA, as … i am beta thalassemia . FPnotebook.com is a rapid access, point-of-care medical reference for primary care and emergency clinicians.

Matemáticamente la ADE se calcula con la fórmula siguiente: High diagnostic accuracy in distinguishing Thalassemia with iron deficiency anemia was RDW index (88.14%), and followed by Mentzer index (86.85%). It is said to be helpful in differentiating iron deficiency anemia from beta thalassemia.. 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. Cuantifica la ANISOCITOSIS (coexistencia de poblaciones de Htíes de diferentes tamaños) -ADE o RDW %. Indeks RDW untuk pasien yang diduga beta thalasemia trit adalah 57% dan anemia defisiensi besi adalah 43% dari 1358 sampel. I’d make the child 13 to 17 years of age so head circumference would not be a factor, but it’s your choice. Information about the open-access article 'Early Screening of Hemoglobinopathy in Indonesia Using Erythrocyte Indices' in DOAJ. Hb electrophoresis. = -0.078; p-value = 0.631), which means that if the hba2 level value increases then the value of the Mentzer index will be reduced, and vice versa. 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%). A low Mentzer Index, calculated from CBC data [MCV/RBC < 13], may suggest this disorder but a hemoglobin electrophoresis would be diagnostic. The six discrimination indices that were examined were as follows: Mentzer Index (MI), Green & King Index (G&K), RDW Index (RDWI), England & Fraser Index (E&F), RDW, and RBC count. Cut off values.

In line with the findings of … We aimed to evaluate red blood cell count (RBC), Mentzer index, red cell distribution width (RDW), RDW index (RDWI), Shine and Lal index (S&L) and Green and King index (G&K) to screen hemoglobinopathy in Indonesia. 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. stream Indices examined were red blood cell (RBC) count, RBC distribution width (RDW), Mentzer index (MI), Shine and Lal index (S&L), England and Fraser index (E&F), Srivastava index (S), Green and King index (G&K), RDW index (RDWI), and Ricerca index (R).

Mentzer index has better sensitivity as iron deficiency anemia screening and RDW index has better sensitivity as Beta Thalassemia trit screening Keywords: Thalassemia β minor, Fe anemia, RDW Mentzer index ABSTRAK Thus the RDW is a good indicator of anisocytosis, and a good screening index especially for ID anaemia and the thalassaemia trait. … Any helpful advice on wbc/rbc/plt assignment given a CBC and no smear? The RDW in thalassemias is usually within or very close to the reference interval, reflecting the uniformity of red cell size (microcytes). Therefore, the RBC count is normal, but the MCV is low, so the index will be less than 13. So Iron Deficiency Anemia (IDA) and Thal are the two big microcytic/hypochromic options that you first learn in hematology. 16,08(1,98) vs 16,20(2,27) (p= 0,72).

I recently got CBC done and my PCV level is 34.7, MCV is 73.4, MCH is 26.22 and WBC count is 3000. Therefore, on the basis of Mentzer’ index and RDW we can diagnose β … Some practitioners use the Mentzer index (Mentzer index = MCV/red blood cell count [RCV]) to discriminate between thalassemia trait and iron deficiency. RDW-CV = (Standard deviation of MCV ÷ MCV) × 100. endobj The RDW index discriminated better than Mentzer's index, discriminant function or the Shine Lal index. 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. RDW, mean (SD) % Mentzer index, mean (SD) RDW index, mean (SD) 121.18 (17.88) 22 29 27.89 (6.11) 130.0 (8.39) 10.32 (1.22) 32.26 (5.05) 5.01 (3.80) 72.66 (2.77) 23.40 (2.59) 31.93 (3.13) 15.81 (2.11) 16.50 (3.02) 261.11 (64.06) 121.21 (15.49) 27 26 25.47 (5.49) 127.0 (8.19) 10.09 (1.42) 31.41 (5.05) 4.37 (0.7) 72.58 (4.10) 23.29 (2.50) 32.32 (3.16) 15.79 (2.12) 17.26 (4.63) Sideroblastic anemia..? Conclusion: The Mentzer index is almost equally reliable index in comparison to the newly found index- RDW. al., showed that by utilizing a complicated formula involving RDW-SD, RBC count, Retic count and Zinc Protoporphyrin levels, 90% of subjects with Iron Deficiency and Heterozygote Thalassemia can be accurately classified.

But if the result is greater than 13, then it When diagnosing a child with anemia, what do you want to consider? Several formulas, based on parameters from the CBC, may be used to calculate a thalassemic index and have been used to differentiate iron deficiency from thalassemia. Mentzer index (MI) (1973) MCV/RBC : RDWI (1987) MCV × RDW/RBC: Shine and Lal (S and L) (1977) MCV × MCV × MCH/100: Srivastava (1973) MCH/RBC: Green and King (G and K) (1989) RDW index has highest positive predictive value (90.91%), while Green value (98.87%). The population was students who were admitted to the University of Dr. Soetomo who came for complete blood count examination. There is no hematological disorder associated with low RDW level.

Indeks Mentzer untuk pasien yang diduga beta thalasemia trit adalah 5,2% dan anemia defisiensi besi adalah 94,8% dari 1358 sampel. Therefore, this formula could be used in initial discrimination of β-thal trait from iron deficiency in adult Thai subjects. An index of less than 13 suggests that the patient has the thalassemia trait, and an index of more than 13 suggests that the patient has iron deficiency. 22.

RDW index was calculated by by multiplying MCV by RDW and divided by RBC. In this study, King-Green formula was reported to have the highest sensitivity and specificity, which as a result, was the most reliable formula followed by Mentzer formula. The two most frequent types of microcytic anemia are beta thalassemia trait (β-TT) and iron deficiency anemia (IDA). Result: According to data analysis, prevalence of anemia in students was 16.9% based on Hb concentrations for diagnosis anaemia based on WHO. 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. The RDW index for patients with suspected beta-thalassemia trit was 57% and iron deficiency anemia was 43% of 1358 samples. hi, my rdw-cv is 15.6, hb 11.9, mcv 65, what do high rdw-cv and low mcv indicate? Combination of low MCV and high RDW is one of the best screening test for the Iron deficiency anemia. 2 0 obj thalassemia syndromes are a group of hereditary disorders characterized by a genetic deficiency in the synthesis of beta-globin chains.
