🔍 What is the Leptospira IgM Antibody Test?
The Leptospira IgM Antibody Test detects IgM antibodies in the blood, produced by the immune system in response to Leptospira bacteria—the cause of leptospirosis. This bacterial infection spreads through contaminated water, soil, or animal urine, often affecting individuals exposed to floodwaters, farms, or rodents.
🎯 Purpose of the Test
Diagnose acute leptospirosis infection
Detect recent exposure to Leptospira bacteria
Differentiate leptospirosis from other febrile illnesses like dengue or malaria
📊 Normal Ranges & Result Interpretation (May vary by lab method)
✅ Negative: No IgM antibodies detected → No current infection
⚠️ Equivocal/Borderline: Retesting may be required for confirmation
🔺 Positive: IgM antibodies present → Suggests recent or active leptospirosis infection
⚠️ Conditions Associated with Positive IgM Results
Leptospirosis (Early-Stage Infection)
Recent exposure to contaminated environments
Possible cross-reactivity with other infections
📝 Additional Testing May Include:
Leptospira IgG Antibody Test (to assess past infection)
PCR Test (for direct bacterial detection in blood/urine)
Complete Blood Count (CBC) & Liver/Kidney Function Tests (to check for organ impact)
👩‍⚕️ When Should You Get Tested?
Flu-like symptoms (fever, chills, headache, muscle pain)
Jaundice, red eyes, or unexplained kidney/liver issues
Exposure to contaminated water, soil, or animals (flooding, farmwork, sewage)
Unexplained febrile illness in leptospirosis-endemic areas
