🔬 What is the Test?
The Absolute Lymphocyte Count (ALC) Test measures the total number of lymphocytes, a type of white blood cell (WBC) that plays a key role in immune function. Lymphocytes help the body fight infections and maintain immune system balance.
📊 Normal Ranges:
Adults & Children: 1,000 - 4,800 cells/µL
Low ALC (Lymphocytopenia): < 1,000 cells/µL (May indicate immune suppression or infections)
High ALC (Lymphocytosis): > 4,800 cells/µL (May indicate viral infections or leukemia)
🩺 Purpose of the Test:
✅ Assess immune system health
✅ Diagnose infections (viral, bacterial, or chronic diseases)
✅ Monitor cancer patients (lymphoma, leukemia)
✅ Evaluate autoimmune disorders (HIV, lupus, rheumatoid arthritis)
✅ Check recovery from chemotherapy, radiation, or organ transplant
🧪 When is it Recommended?
🔹 Frequent infections or unexplained fevers
🔹 Swollen lymph nodes or persistent fatigue
🔹 Monitoring immune disorders (HIV, AIDS, leukemia, lymphoma)
🔹 Before or during chemotherapy, radiation, or immunosuppressive treatments
📝 How is the Test Done?
1️⃣ A blood sample is drawn from a vein.
2️⃣ The lab calculates ALC from total WBC & lymphocyte percentage.
3️⃣ Results help assess immune response and disease progression.
⚠️ What Do Abnormal Results Mean?
📈 High ALC (Lymphocytosis):
Viral infections (mononucleosis, hepatitis, HIV)
Chronic bacterial infections (tuberculosis, syphilis)
Leukemia, lymphoma, or other blood cancers
📉 Low ALC (Lymphocytopenia):
HIV/AIDS or other immune-suppressing conditions
Autoimmune diseases (lupus, rheumatoid arthritis)
Chemotherapy, radiation therapy, or bone marrow disorders
Severe infections like sepsis
