    Efficiency in the alarm signs of immature cells reported from the automated hematology analyzer of the “Beckman Coulter 600“ equipment with the revision of the peripheral plate in adult patients, Hospital Nacional Hipólito Unanue, El Agustino Peru, December 2019 - February 2020

    The objective was to determine the efficiency of immature cell alarms reported by the automated hematological analyzer in the "Beckman Coulter 600" with peripheral smear review in adult patients at the National Hipólito Unanue Hospital from December 2019 to February 2020. A total of 489 reports of immature leukocytes were evaluated. The efficiency, sensitivity, specificity, positive and negative predictive values, as well as the Kappa concordance index, were calculated. An efficiency of 95.3%, sensitivity of 70.0%, specificity of 95.8%, positive predictive value of 25.9%, and negative predictive value of 99.4% were found. The Kappa concordance index was 0.36. The efficiency level of the immature cell alarms in the central laboratory, reported by the Beckman Coulter equipment at the National Hipólito Unanue Hospital, was 95.3%. The sensitivity and specificity of the alarms of the Beckman Coulter automated equipment were 70.0% and 95.8%, respectively. The positive and negative predictive values of the alarms were 25.9% and 99.4%. The degree of concordance between the immature cell alarms of the automated hematological analyzer and the peripheral smear was 0.36, classified as mild.
