Increased Total Leukocyte Count (TLC) and Differential Leukocyte Count (DLC) are usually due to infection, inflammation, or stress, as your immune system is active. Take proper rest, stay hydrated, eat a balanced diet, and watch for symptoms such as fever, pain, or weakness to help determine the cause. Avoid self-medication and keep your routine simple while your body recovers. Consult a doctor with your reports to determine the exact cause and guide appropriate treatment.
