Chlamydia Pneumoniae IgG antibodies

Chlamydia Pneumoniae IgG antibodies – this is a blood test to determine whether a person was infected with the bacteria Chlamydia pneumoniae, which causes respiratory tract infections. This bacterium spreads through airborne droplets and infects the respiratory tract mucous membranes, potentially causing pharyngitis, laryngitis, sinusitis, or atypical pneumonia.

The infection is characterized by a dry, persistent cough that can last for a long time. Not everyone who hosts chlamydia or mycoplasma in their nasopharynx becomes ill – it depends on the immune status of the body. However, even without symptoms, it is still possible to infect others.

IgG antibodies appear in the blood 4-6 weeks after infection, thus indicating a past or chronic infection. In cases of reinfection, the IgG titer increases rapidly – within 1-2 weeks, which allows for the identification of a newly started infection, when IgM antibodies may not form.

Test principle: Chlamydia pneumoniae IgG antibodies are determined by an immunochemical method from venous blood. The results help assess immunity or the timing of infection, especially in conjunction with an IgM test.

Recommendations:

• Recommended for patients with prolonged cough or recurrent respiratory tract infections.
• Useful for assessing whether a person has previously encountered this infection.
• Performed in conjunction with an IgM test to accurately determine the stage of infection.
• Conducted in cases of bronchitis, sinusitis of unknown origin, or suspected chronic infection.
• No specific preparation is required for the test.
