[Seasonal variations in hematocrit in Kinshasa, Democratic Republic of Congo]
The aim of the present study was to determine whether the concentration of blood cells in plasma varies seasonally in Kinshasa, DR Congo. Changes in hematocrit of 104 volunteer blood donors in good health were followed during the two seasons of the year - rainy and dry. Hematocrit was higher during the rainy season than during the dry season.
