In a stress leukogram, what is typically seen in regards to lymphocytes?

In a stress leukogram, there is typically a decrease in the number of lymphocytes. This pattern occurs due to stress-induced release of cortisol from the adrenal glands, which affects the distribution and proliferation of leukocytes. Cortisol leads to lymphocyte apoptosis (programmed cell death) and causes lymphocytes to redistribute from the circulation to the lymphoid tissues, resulting in a reduced number of circulating lymphocytes. This is a common physiological response observed in situations involving stress, trauma, or illness, highlighting the body's adaptive mechanisms to manage stress. In contrast, other white blood cell types, particularly neutrophils, may increase in number during a stress response, further distinguishing the changes seen in lymphocyte populations.
