Lymphocytosis refers to a medical condition characterized by an elevated number of lymphocytes in the bloodstream. Lymphocytes are a type of white blood cell that plays a crucial role in the immune system, defending the body against infections and diseases. Lymphocytosis can be categorized into two main types: absolute lymphocytosis and relative lymphocytosis.

Absolute Lymphocytosis: This occurs when there is an actual increase in the total number of lymphocytes in the blood. It can be a result of various underlying conditions, such as viral infections (e.g., mononucleosis), bacterial infections, chronic lymphocytic leukemia (CLL), lymphoma, autoimmune disorders, and other immune system-related diseases.

Relative Lymphocytosis: In this case, the absolute number of lymphocytes may not be elevated, but the proportion of lymphocytes is higher than other types of white blood cells, like neutrophils. This can occur due to factors such as stress, corticosteroid use, and certain medications.

"Blasts/ABN lympho" typically refers to the presence of abnormal lymphocytes or lymphoblasts in the blood or bone marrow. Lymphoblasts are immature forms of lymphocytes that can be indicative of underlying conditions like acute lymphoblastic leukemia (ALL) or other forms of leukemia and lymphomas. The presence of these abnormal cells requires further investigation to determine the specific cause and appropriate treatment.

It's important to note that the interpretation of these terms should be done by a qualified healthcare professional, as they will take into account the individual's medical history, clinical symptoms, and diagnostic tests to make an accurate diagnosis and develop an appropriate treatment plan.
