📌 What is the Amoebic Serology Test?
A blood test used to detect antibodies against Entamoeba histolytica, the parasite responsible for amoebic liver abscess and amoebiasis.
📊 Normal Range
✔ Negative – No detectable antibodies (indicates no current or past infection)
🚨 Positive Result May Indicate:
🔺 Amoebic liver abscess
🔺 Intestinal amoebiasis
🔺 Past infection with E. histolytica
🎯 Purpose of the Test
✅ Helps diagnose amoebic liver abscess and systemic amoebiasis
✅ Differentiates amoebic vs. pyogenic liver abscess
✅ Supports diagnosis in patients with fever, right upper abdominal pain, and liver swelling
✅ Used alongside imaging tests (ultrasound/CT scan) for confirmation
💡 Key Facts
🔹 Antibodies appear within 7-10 days after infection and can persist for months
🔹 Serology may remain positive even after treatment, so clinical correlation is needed
🔹 Stool tests and imaging are often used to confirm diagnosis
