What Is A Mycoplasma IgG/IgM Qualitative Test?
Mycoplasma IgG/IgM qualitative test is serological test that detects the presence of IgG and IgM antibodies against the mycoplasma pneumoniae, a bacteria that causes respiratory infections such as pneumonia, bronchitis and tracheobronchitis. The test helps in the diagnosis of acute or recent infections by identifying the response of immune system to pathogens. The test identifies IgM antibodies that indicates active infection and IgG antibodies that suggest a past exposure or a resolving infection.
Mycoplasma Pneumoniae infections are often referred to as “walking pneumonia” are common in children and adults, especially in crowded environments like schools or workplaces. Symptoms can range from mild respiratory issues to severe pneumonia. Early diagnosis is crucial for appropriate treatment, which typically involves antibiotics like macrolides or tetracyclines.
How is the Test Performed?
This test requires a blood sample.
Sample Collection
A healthcare professional draws a blood sample which is sent to a laboratory.
Lab Analysis
The blood sample is tested using enzyme-linked immunosorbent assay (ELISA) or immunofluorescence techniques to detect the presence of IgG and IgM antibodies. The test is qualitative meaning it provides a positive or negative result rather than a numerical value.
Result
Results are usually available within 24 to 48 hours.
What are the symptoms that prompt this test?
The Mycoplasma IgG/IgM qualitative test is often ordered when a patient exhibits symptoms of a respiratory infection or has been exposed to someone with a confirmed Mycoplasma pneumoniae infection. These symptoms may include:
Adults
- Persistent dry cough
- Sore throat
- Fatigue and weakness
- Fever and chills
- Shortness of breath
- Chest pain
Children
- Wheezing
- Ear pain or ear infection
- Fever and irritability
- Loss of appetite
- Runny nose
What are Normal Ranges for This Test?
The Mycoplasma IgG/IgM qualitative test is a qualitative test. It detects the presence or absence of antibodies. There are no specific normal ranges for this test.
- Negative Result –No IgG or IgM antibodies detected.
- Positive Result –IgG or IgM antibodies detected, indicating an active or past infection.
**The above mentioned range is for information purpose only. Normal levels are dependent on a number of factors including age, gender, testing method and health condition of patient etc. Result interpretation should be done by a qualified doctor or healthcare professional.**
What Happens if Test Results Show Abnormal Levels?
If the test results show positive IgM, it indicates an active infection for which your doctor will prescribe antibiotics depending on the severity of infection. If IgG is positive but IgM is negative, it shows past exposure or a resolving infection for which no immediate treatment is necessary unless the symptoms persist.
Your doctor may also order further tests such as PCR tests or a chest X-ray to check the severity of the infection. Lung function tests may also be ordered for individuals with chronic respiratory symptoms. Supportive care or hospitalization may also be required for patients with severe infections.
