Diagnosing acute leukemia, including Acute Lymphoblastic Leukemia (ALL), typically involves a comprehensive evaluation by your physician. This process relies on a combination of medical history, physical examination, and specialized laboratory tests that analyze blood and bone marrow cells.
Medical History
Your doctor will gather detailed information about your health habits, past illnesses, and previous treatments to build a complete medical profile.
Physical Examination
A thorough physical examination will be conducted to assess your overall physical health and identify any unusual findings or symptoms. During this examination, your lymph nodes, spleen, and liver will be carefully checked for any signs of enlargement.
Complete Blood Count (CBC)
A blood sample is collected and analyzed to measure various parameters crucial for diagnosis:
* The quantities of red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
* The amount of hemoglobin bound to red blood cells.
* The percentage of the blood sample composed of red blood cells, known as hematocrit.
In patients with Acute Lymphoblastic Leukemia, CBC results typically show low levels of hemoglobin (Hgb) and platelets (Plt), while the white blood cell (WBC) count may be either low or high.
Blood and Urine Biochemistry Tests
These tests involve analyzing blood samples to measure the levels of specific substances released into the bloodstream by organs and tissues. Abnormally high or low levels of these substances can aid in diagnosis. For instance, in ALL, levels of LDH and uric acid may be elevated.
Peripheral Blood Smear
Your doctor will examine a blood sample under a microscope to identify any changes in the shape, size, or appearance of blood cells. This examination is critical for diagnosing acute leukemia. It also allows the physician to assess the quantity, types, and morphology of white blood cells and the platelet count. In ALL, "lymphoblasts," which are immature leukemia cells, may be observed. However, their absence in a peripheral blood smear does not rule out the diagnosis.
Bone Marrow Aspiration and Biopsy
This procedure involves collecting and examining bone marrow, a spongy tissue found within some large bones. It is essential for confirming the diagnosis of acute leukemia and for monitoring the disease's progression. Bone marrow aspiration (collecting liquid marrow) and biopsy (collecting a small piece of solid marrow) are usually performed simultaneously.
