Adenovirus IgA At
The adenovirus IgA At test is crucial for diagnosing and monitoring adenovirus infections, and it is available at IntroLab in Belgrade.
What is adenovirus IgA At?
Adenovirus IgA At are specific proteins produced by the immune system in response to an adenovirus infection. These antibodies are created by B lymphocytes, which transform into plasma cells that produce antibodies. These cells are mainly located in lymph nodes, the spleen, tonsils, and other lymphatic system parts, but can also be found in other body areas where immune responses occur. Notably, IgA antibodies are found on mucous membranes and in body fluids like saliva, tears, and secretions from the respiratory and digestive systems, acting as the first line of defense against infections.
Adenoviruses form a large group of viruses that can lead to various illnesses, including:
- Colds
- Pharyngitis
- Bronchitis
- Pneumonia
- Diarrhea
- Conjunctivitis
- High fever
- Bladder inflammation
- Neurological diseases
When the body encounters an adenovirus, it produces specific IgA antibodies to neutralize the virus and aid in eliminating the infection.
Why is this test important?
Measuring adenovirus IgA antibodies is crucial for confirming or ruling out an adenovirus infection. Elevated levels typically indicate an active or recent infection, while low or absent levels usually suggest the absence of infection or a successful recovery.
When is the adenovirus IgA At test performed?
This test is recommended if a person shows symptoms that may indicate an adenovirus infection, such as:
- Fever
- Sore throat
- Muscle pain or swollen eyelids
It is particularly useful for monitoring the effectiveness of treatment in individuals who have had an adenovirus infection.
How is the test conducted?
The test is performed using a blood sample. Blood is drawn from a vein in the arm through a straightforward and quick procedure.
Test specifics
This test is highly specific and sensitive, providing accurate detection of antibodies. However, levels may be elevated in individuals with certain chronic conditions, such as HIV, or those who have recently received an adenovirus vaccine.
Subtypes of the test
The Adenovirus IgA At test is a key method for studying the immune response to adenovirus. For a more detailed and comprehensive understanding, other subtypes should also be considered.
- Adenovirus IgG At: This class of antibodies appears after IgA antibodies peak and begin to decline. The presence of IgG antibodies may indicate prior exposure to adenovirus and potential immunity.
- Adenovirus IgM At: This subtype of antibodies is typically produced first at the onset of infection. The presence of these antibodies generally indicates a new or active adenovirus infection.
Measuring Adenovirus IgA At, along with these other antibody subtypes, allows experts to gain a complete understanding of the immune response to adenovirus infection.

Frequently asked questions
What is adenovirus and when is the Adenovirus IgA test done?
Adenovirus is a large group of viruses that can cause colds, pharyngitis, bronchitis, pneumonia, diarrhea, conjunctivitis and bladder inflammation. The Adenovirus IgA At test measures IgA antibodies, which the body produces in response to infection and which are found on mucous membranes. Elevated levels usually point to a current or recently resolved infection. At IntroLab laboratory the test costs 1,900 RSD, is done from venous blood, and results are ready in up to 4 days.
Which adenovirus symptoms in adults are a reason to get tested?
Adenovirus infection may be suggested by fever, sore throat, and pain in the muscles or eyelids, and, depending on where the infection develops, also by cough, red eyes or diarrhea. When such symptoms are present, a doctor may order the Adenovirus IgA At test, which at IntroLab laboratory helps confirm or rule out an adenovirus infection. The test can also be useful for following the course after an infection. The result is always interpreted by a doctor, together with an examination.
What is the difference between adenovirus IgA, IgM and IgG antibodies?
Adenovirus IgM antibodies are usually produced first and point to a new or active infection. IgA antibodies act on mucous membranes and are elevated in a current or recent infection. IgG antibodies appear later and may indicate earlier exposure to adenovirus and acquired immunity. That is why at IntroLab laboratory Adenovirus IgA At is often interpreted together with IgM and IgG results, and with unclear IgG results a doctor may also order Adenovirus IgG Avidity (3,100 RSD).
