Agreement in the Count and Morphological Identification of Platelets in Blood Smears Between Medical Technologists from Hospitals and Specialized Institutes in Metropolitan Lima and Callao, October 2017 – March 2018
(Universidad Privada Norbert Wiener, 2018-05-31) Conde Sanabria, Ricardo; Rodríguez Ruiz, Lucía Raquel; Alegre Torres, Justo Tobías
The objective is to find the degree of concordance in platelet count and morphological identification on blood smears between Medical Technologists. The study is descriptive, prospective, and cross-sectional. During the sampling period, 106 Medical Technologists working in the Hematology area participated. A 14-question questionnaire, 3 stained blood smears, and 4 platelet morphology images were validated by 3 expert judges. To measure the degree of concordance, Cohen's Kappa coefficient was used. A Kappa coefficient of 0.309, indicating weak agreement for platelet counting on blood smears, and a Kappa of 0.429, indicating moderate agreement for platelet morphological identification, were obtained. To ensure the reliability of the blood smear study, proper sample collection, smear specifications as per CLSI, optimal staining, good review technique, experienced analysts, and quality control programs should be considered. Promoting consensus on hematological cytomorphology is essential to standardize the diverse criteria used today.

Evaluation of 3 indirect methods for estimated platelet count in peripheral blood slim Lima ‐ Perú, 2022
(Universidad Privada Norbert Wiener, 2023-05-21) Conde Sanabria, Ricardo; Huamán Cárdenas, Victor Raul
The inaccuracy in platelet counts using automated equipment in cases of thrombocytopenia or certain types of thrombocytosis may cause alterations in platelet variability due to the limitations of the methodology. When "Flags" or alerts appear in hematology analyzers, their verification is still carried out using a peripheral blood smear, where qualitative and quantitative alterations in the three blood cell lines can be observed. In Metropolitan Lima and Callao, Clinical Laboratory Technologists who estimate platelet counts in blood smears after detecting platelet alerts in their equipment use various indirect methods based on field parameters or erythrocytic indices, such as the 20,000 factor method, Fonio method, Dameshek method, and others that are less common. Objective: To evaluate the difference between three indirect methods for estimating platelet counts compared to the gold standard in peripheral blood smears. Materials and Methods: The research method is hypothetical-deductive, applied, quantitative, and experimental with a diagnostic study design.
