🧪 What is the Mycoplasma pneumoniae IgM Test?
The Mycoplasma pneumoniae IgM test detects IgM antibodies specific to Mycoplasma pneumoniae, a bacterium that causes atypical pneumonia, especially in children and young adults.
- IgM antibodies typically appear within 7–10 days of infection.
- Used for early diagnosis of recent or active Mycoplasma infection.
❓ Why is the Test Done?
To:
- Diagnose acute respiratory infection caused by Mycoplasma pneumoniae
- Investigate persistent dry cough, low-grade fever, fatigue
- Evaluate community outbreaks of atypical pneumonia
- Differentiate Mycoplasma from other causes of pneumonia
📊 Normal Range & Interpretation
Result | Interpretation |
|---|---|
Negative | No IgM detected – unlikely active infection |
Positive | Suggests recent or active Mycoplasma infection |
Equivocal | Borderline – repeat testing recommended |
IgM levels may persist for weeks or months post-infection.
📈 Interpretation of Results
IgM Result | Possible Meaning |
|---|---|
Positive IgM | Recent Mycoplasma pneumoniae infection |
Negative IgM | No current/recent infection OR too early to detect antibodies |
Paired IgG Rise | Rising IgG titer supports diagnosis if IgM is negative |
🧠 Associated Organs & Conditions
Organ/System | Associated Conditions |
|---|---|
Respiratory Tract | Atypical pneumonia, tracheobronchitis, chronic cough |
Nervous System | Encephalitis, transverse myelitis, Guillain-Barré syndrome |
Hematologic | Hemolytic anemia (due to cold agglutinins) |
Skin | Stevens-Johnson syndrome, rash |
Others | Otitis media, myocarditis |
🔄 Related / Follow-Up Tests
- Mycoplasma IgG – to assess past exposure or paired testing
- PCR for Mycoplasma DNA – highly specific, especially in early phase
- Chest X-ray – for pneumonia evaluation
- Cold agglutinin test – may be elevated in Mycoplasma infection
- CBC – may show leukocytosis or mild anemia
