Reference Interval:
 
Test Number Components Reference Interval
0051189Chlamydia pneumoniae Antibody, IgG by ELISA 0.99 IV or less: Negative - No significant level of C. pneumoniae IgG antibody detected.
1.00-1.10 IV: Equivocal - Questionable presence of C. pneumoniae IgG antibody detected.  Repeat testing is suggested after 2-4 weeks.
1.11 IV or greater: Positive - IgG antibodies of C. pneumoniae detected, which may suggest current or past infection.
0051190Chlamydia pneumoniae Antibody, IgM by ELISA 1.39 IV or less: Negative - No significant level of C. pneumoniae IgM antibody detected.
1.40-1.50 IV: Equivocal - Questionable presence of C. pneumoniae IgM antibody detected.  Repeat testing is suggested after 2-4 weeks.
1.51 IV or greater: Positive - IgM antibodies to C. pneumoniae detected, which may suggest current or recent infection.

Interpretive Data:
Extensive cross-reactivity exists between Chlamydia species.  Therefore, if the clinical diagnosis is unclear, IFA testing for all three species is recommended.

Please refer to Statement A in the Compliance Statements section in the front of the Laboratory Test Directory.
