There are different types of blood tests, with the most essential being biochemical and hematological analysis. Our biostatistical study, conducted at the central laboratory of the Ahmed MEDEGHRI Public Hospital in Ain Temouchent, focused on the biological results of 82 patients, with the aim of analyzing certain hematological and biochemical variations according to age and gender. The demographic analysis revealed a female predominance and a strong representation of individuals over the age of 50. Biologically, several abnormalities were identified: a tendency toward anemia in women, elevated erythrocyte sedimentation rate in older subjects indicating a possible inflammatory state, as well as increased blood glucose and renal markers with age, reflecting metabolic aging. These findings need to be confirmed by studies on a larger scale. This study highlights the value of a biostatistical approach to better understand the biological profiles of a population by identifying the most frequent abnormalities. It provides a useful basis for guiding screening and prevention efforts.frBio-statistique- Bilan biochimique- Bilan hématologique- âge -sexe- Ain Témouchent.Biostatistic- Biochemical testing- Hematological testing- Age-Gender-Ain TemouchentThesis
