Comparative Analysis of Leucocyte Count (Total and Differential) in Patients with Leucocytosis using Sysmex XN550-L Series (5 Part) Automated Analyzer and Conventional Manual Technique in a Tertiary Care Hospital in Rural Haryana

Normal concentration of WBCs in blood varies between 4000 and 11,000 per microliter and are classified intotwo variants namely granulocytes and agranulocytes on the basis of presence and absence of granules.Manual methods of calculation of TLC include- Neubauer chamber and estimating WBC on leishman stainedslides whereas automated methods are based on impedance or light scattering technology. The study comparedthe efficacy of both these methods in statistical terms using Chi Square test. 100 cases of leucocytosisanalyzed over a period of 1 year at MMIMSR, Mullana, Haryana revealed leucocytosis prevalent in 4-6 decadeof life with slight male predominance. The pearson coefficient for TLC came out to be p value =0.215 (notsignificant) but for DLC, calculations revealed p values for polymorphs, lymphocytes, eosinophils andmonocytes to be significant (p value =0.000 each). To conclude, standard manual methods should be advocatedas special practice where there is definite need of morphological and quantitative evaluation of WBCs and tovalidate the automated methods by which the laboratories can optimize patient care and not as a replacement

Significance of Mentzer Index and Erythrocyte Indices to Evaluate Erythrocyte Morphology and Spectrum of Anemia in Adult Population in a Tertiary Care Hospital in Rural Haryana

Anemia, reduced red cell mass below normal range, results in reduction of oxygen carrying capacity of bloodthat results in tissue hypoxia. MCV, MCH, MCH and RDW represent a sensitive indicator to study erythrocytemorphology. Mentzer Index recommended MI<13 to be suggestive of â-TT and MI>13 for Iron deficiencyanemia. 100 cases were analyzed prospectively over a span of 1 year at MMIMSR, Mullana. The studyrevealed 34% of patients to be in age group of 21-30 years with (59%) female predominance out of whichmajority of cases were of moderate anemia (73%). Erythrocyte indices revealed pattern with majority ofsamples having MCV, MCH and MCHC to be in normal range while RDW showed increased values. Mentzerindex came out to be >14 in 96% of samples. To conclude evaluation of erythrocyte indices and Mentzerindex aids in quatitative assessment of anemia and also to distinguish between iron deficiency anemia andthalassemia trait.
