Predicting academic success is one of the fundamental tasks of learning analytics. Generally accepted predictive criteria include academic performance. However, there is limited information about the influence of morphofunctional factors indicating the state of health in students on their academic performance. Therefore, the purpose of this study was to investigate potential predictors of learning success based on blood cell data. Materials and methods. The experiment involved 79 apparently healthy second-year students of Kursk State Medical University (mean age 18.97 ± 0.14 years), 67 % female and 33 % male. An anonymous survey was conducted using Google Forms. The following information was obtained: rating points for the first semester of studying the discipline “Histology, Embryology, Cytology”, time spent preparing for classes, and some complete blood count data (concentrations of red blood cells, white blood cells, platelets and haemoglobin; haematocrit; neutrophil and lymphocyte fractions). Depending on the points scored, the students were divided into three groups: satisfactory performance (64–79 points, n = 25), good performance (80–90 points, n = 41) and excellent performance (91– 100 points, n = 13). Results. A significant positive correlation between platelet count and rating points scored was found (r = 0.411, p = 0.00017). At the same time, platelet concentration differed significantly between the three groups of students (p = 0.002) and was higher in the group with excellent performance compared to students who demonstrated good (p = 0.007) or satisfactory (p = 0.00045) performance. One of the reasons behind the increase in platelet concentration in students with currently high academic performance may be the neuropsychic stress they experience due to a longer and more thorough preparation for classes. Thus, platelet count can be used as a predictor of students’ academic success.
