Adenovirus, IgG OR IgM Antibody Sample Type: Serum

Adenovirus IgG/IgM Antibody Test
Sample Type: Serum

Purpose:
This test detects IgG and/or IgM antibodies against adenovirus, which causes a range of infections including respiratory illness, conjunctivitis, gastroenteritis, and more.

Clinical Use:

IgM antibodies indicate a recent or current infection

IgG antibodies suggest past exposure or immunity

Helps diagnose adenovirus in patients with flu-like symptoms, especially when other viral causes are ruled out

Interpretation:

IgM positive / IgG negative: Recent or acute infection

IgM positive / IgG positive: Ongoing or recent infection with immune response

IgM negative / IgG positive: Past infection or immunity

IgM negative / IgG negative: No prior exposure

Limitations:

IgM may be absent in early infection or immunocompromised patients

Cross-reactivity may occur with other viruses, so results should be interpreted with clinical findings
