Full Name

Anti-Aspergillus IgM Antibody Test

Sample Type

Blood (serum)

Fasting Required

❌ Not required

Method

ELISA (Enzyme-Linked Immunosorbent Assay)

Test Category

Infectious Disease – Fungal

Allergic (ABPA)

Hypersensitivity in asthmatics and cystic fibrosis patients

Chronic Pulmonary Aspergillosis

Slow-progressing lung infection in damaged lungs

Invasive Aspergillosis

Severe, fast-spreading disease in immunocompromised individuals

Respiratory (Lungs)

Primary site for colonization/infection

Immune System

IgM response indicates recent infection or immune sensitization

CNS, Sinuses

Can be affected in disseminated or severe cases

🧪 Detect early Aspergillus infection

Especially in invasive pulmonary aspergillosis (IPA)

🧫 Support diagnosis when cultures are inconclusive

Especially in immunocompromised patients

🩺 Assess patients with acute respiratory symptoms

When imaging shows nodules or infiltrates

Positive

Recent exposure or infection with Aspergillus; supports active disease

Negative

Less likely to be acute Aspergillus infection, though not conclusive

Invasive Pulmonary Aspergillosis

Useful for early detection

Allergic Bronchopulmonary Aspergillosis (ABPA)

Sometimes shows IgM rise, more often IgE/IgG

Fungal Sinusitis

May elevate in acute cases

Aspergillus IgG

Detects chronic or prior exposure

Aspergillus IgE

For ABPA (allergic form)

Galactomannan Antigen

Detects active fungal components, useful in invasive disease

Chest HRCT

To look for cavitary lesions or fungal balls

Bronchoalveolar Lavage (BAL) + Culture/PCR

Confirms diagnosis in suspicious cases

Sample

Blood (serum)

Fasting Required

No

Used For

Recent or acute Aspergillus infection detection

Associated Organs

Lungs, sinuses, systemic (rare)

Positive In

Acute aspergillosis, early-stage infection

Not Useful For

Chronic or past infections alone
