Overview of the Atypical Pneumonia Screen
The Atypical Pneumonia Screen is a specialist blood test that measures antibodies associated with three recognised causes of atypical respiratory infection: Chlamydia pneumoniae, Mycoplasma pneumoniae and Legionella.
The profile contains 5 antibody markers, including IgG and IgM measurements for Chlamydia pneumoniae and Mycoplasma pneumoniae together with Legionella antibody screening. Looking at these markers can provide additional laboratory information where an atypical respiratory infection is being considered.
Atypical pneumonia can sometimes present differently from more typical bacterial pneumonia. Symptoms may develop gradually and can include persistent cough, fever, headache, fatigue, muscle aches and general respiratory discomfort. However, these symptoms overlap considerably with viral infections and other respiratory conditions.
This test measures the immune response to these organisms rather than directly detecting the bacteria themselves. For that reason, antibody results need careful interpretation according to the timing of symptoms, previous exposure and any other investigations that have already been performed.
The Atypical Pneumonia Screen does not replace clinical examination, chest imaging, PCR, antigen testing or other microbiological investigations where these are medically indicated.
What Does the Atypical Pneumonia Screen Check ?
This test measures 5 antibody markers associated with Chlamydia pneumoniae, Mycoplasma pneumoniae and Legionella.
Chlamydia Pneumoniae IgG
Measures IgG antibodies to Chlamydia pneumoniae. IgG antibodies can indicate previous exposure or a developing immune response and may remain detectable after an infection has resolved.
Chlamydia Pneumoniae IgM
Measures IgM antibodies to Chlamydia pneumoniae. IgM may be associated with a more recent immune response, although interpretation depends heavily on when the sample is collected in relation to symptoms.
Legionella Ab Screening
Screens for antibodies associated with Legionella infection. A positive antibody result may provide evidence of exposure but does not by itself confirm active Legionnaires' disease.
Mycoplasma pnemoniae IgM
Measures IgM antibodies associated with Mycoplasma pneumoniae. IgM may support evidence of a more recent immune response when interpreted alongside symptoms, timing and other investigations.
Mycoplasma pneumoniae IgG
Measures IgG antibodies to Mycoplasma pneumoniae. IgG may reflect previous exposure and should not automatically be interpreted as evidence of a current active infection.
Who May Benefit From the Atypical Pneumonia Screen?
This test may be suitable for people whose clinician is investigating persistent or unusual respiratory symptoms and wants additional information about possible atypical bacterial causes.
Persistent respiratory symptoms - May provide additional laboratory information where coughing, fever or respiratory symptoms have continued longer than expected.
Possible atypical pneumonia - Assesses antibody responses associated with three organisms recognised as causes of atypical respiratory infection.
Prolonged cough - Mycoplasma pneumoniae and Chlamydia pneumoniae can be considered among several possible causes of a persistent cough.
Unexplained fever with respiratory symptoms - Serology may provide supporting information when considered alongside clinical assessment and other investigations.
Possible Mycoplasma pneumoniae exposure - Measures both IgM and IgG antibodies associated with Mycoplasma pneumoniae.
Possible Chlamydia pneumoniae exposure - Measures both IgM and IgG antibodies associated with Chlamydia pneumoniae.
Possible Legionella exposure - Includes Legionella antibody screening within the wider atypical pneumonia assessment.
Respiratory illness that has not followed the expected course - Additional testing may sometimes be considered when symptoms persist despite initial management.
Private specialist respiratory testing - Access the screen through London Blood Tests with clinic and home or hotel phlebotomy options.
How to Prepare
Symptoms and Reasons to Consider the Atypical Pneumonia Screen
You may wish to consider the Atypical Pneumonia Screen where persistent respiratory symptoms are being investigated and atypical bacterial infection forms part of the clinical differential diagnosis.
Persistent cough - A prolonged dry or productive cough can occur with Mycoplasma pneumoniae, Chlamydia pneumoniae and many other respiratory infections.
Fever - Fever can accompany pneumonia and other infections but cannot identify the responsible organism by itself.
Persistent fatigue - Significant tiredness can occur during and after respiratory infections and may warrant further assessment when prolonged.
Headache associated with respiratory illness - Headache can occur alongside systemic symptoms in some atypical respiratory infections.
Muscle aches - Myalgia can accompany infectious illnesses and may occur alongside cough, fever or fatigue.
Shortness of breath - Breathlessness may occur with pneumonia and requires appropriate clinical assessment, particularly if new, severe or worsening.
Chest discomfort - Chest pain or discomfort during a respiratory illness may require clinical examination and imaging rather than blood antibody testing alone.
Symptoms persisting despite initial treatment - Further investigation may be appropriate where a respiratory illness has not improved as expected.
Possible environmental Legionella exposure - Legionella can be associated with contaminated water systems, although the most appropriate diagnostic test depends on the timing and clinical circumstances.
A clinician has recommended atypical pneumonia serology - Antibody testing may provide additional information alongside imaging, PCR, urinary antigen testing or other microbiological investigations.
Symptoms associated with atypical pneumonia overlap considerably with influenza, COVID-19, other viral infections, conventional bacterial pneumonia and non-infectious respiratory conditions. This blood test cannot determine the cause of symptoms without appropriate clinical context.
Antibody responses also develop over time. A sample taken very early in an illness may be negative even when infection is present, while IgG antibodies can remain detectable following older exposure.
Seek urgent medical attention for significant breathing difficulty, severe chest pain, confusion, fainting, blue or grey lips or skin, rapidly worsening illness or other severe respiratory symptoms rather than waiting for routine blood test results.

When Will I Receive My Results?
The expected turnaround time for the Atypical Pneumonia Screen is approximately 7 business days.
Results are sent securely by email once specialist laboratory analysis and authorisation are complete. Turnaround generally begins when the laboratory receives your blood sample rather than necessarily from the time it is collected.
Specialist serology can occasionally require repeat analysis, confirmatory review or additional laboratory processing, which may extend the expected turnaround.
Understanding Your Results
The Atypical Pneumonia Screen measures antibody responses rather than directly detecting Chlamydia pneumoniae, Mycoplasma pneumoniae or Legionella bacteria. This is important when interpreting positive and negative results.
An IgM-positive result may be compatible with a relatively recent immune response, but it does not automatically prove current active infection. IgM antibodies may take time to appear, can persist for a period after infection and can occasionally produce non-specific results.
An IgG-positive result may indicate previous exposure and can remain detectable long after an infection has resolved. In some clinical circumstances, comparison between samples taken at different times can be more informative than one isolated IgG result.
A negative antibody result does not completely exclude infection, particularly if testing was performed early in the illness before a measurable antibody response developed.
Legionella serology also requires careful clinical interpretation. When acute Legionnaires' disease is strongly suspected, urinary antigen testing, respiratory PCR or culture may sometimes be preferred depending on the clinical circumstances.
Results should be considered alongside symptoms, examination findings, duration of illness, chest imaging and any other microbiological tests. A positive result does not automatically establish the cause of pneumonia, while a negative result does not rule out every atypical respiratory infection.
