What's this test for?

This test is ideal if you've been experiencing persistent cough, chest congestion, or breathing difficulties that won't go away. It helps identify whether you have a current or past Mycoplasma pneumoniae infection, a common cause of walking pneumonia that can linger for weeks. Many people use this test when they've had respiratory symptoms that don't respond to typical treatments or when trying to understand recurring lung infections.

How should I prepare for this test?

No special preparation is required for this antibody test. You don't need to fast, and you can take your regular medications. The test measures antibodies in your blood, which aren't affected by food, drink, or time of day. Simply schedule your blood draw at your convenience.

What's included in this test?

This test measures two types of antibodies your immune system produces in response to Mycoplasma pneumoniae bacteria. IgM antibodies appear first during an active or recent infection, while IgG antibodies indicate past exposure or recovery. Together, these measurements help determine whether you have a current infection that needs treatment, are recovering from a recent infection, or had exposure in the past.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your antibody levels mean for your respiratory health and whether you have a current or past infection. These notes include personalized recommendations about treatment options, whether antibiotics might help, and when to follow up with a pulmonologist or primary care doctor. You'll also get the standard lab report and can track your antibody levels over time using our trends feature to monitor your immune response or reinfection risk.
When will I get my results?
Results are typically available within 3-5 business days after your blood sample reaches the laboratory. You'll receive an email notification when your results are ready to view in your secure online account. If the lab encounters any technical issues or needs to rerun the test, it may take slightly longer.
Who should consider getting this test?
This test is valuable for anyone with prolonged respiratory symptoms like a persistent dry cough, chest discomfort, or mild fever that lasts several weeks. It's especially useful if you've been diagnosed with pneumonia or bronchitis, if your symptoms aren't improving with standard antibiotics, or if you've been exposed to someone with a confirmed Mycoplasma infection. Healthcare workers, students in dormitories, and people in close-contact settings may also benefit from testing.
What symptoms indicate I may need this test?
Common symptoms include a persistent dry cough that gradually worsens, chest discomfort or tightness, mild fever, fatigue, and headaches. Unlike typical pneumonia, you might feel well enough to continue daily activities, which is why it's called walking pneumonia. You may also experience a sore throat, ear pain, or wheezing that develops slowly over days to weeks.
How can I naturally support my respiratory health during recovery?
Stay well-hydrated with water, warm teas, and broths to help thin mucus and soothe your airways. Get plenty of rest to allow your immune system to fight the infection effectively. Use a humidifier to keep airways moist, which can ease coughing and breathing. Avoid smoking and secondhand smoke, and consider immune-supporting nutrients like vitamin C, zinc, and vitamin D through diet or supplements.
What is Mycoplasma pneumoniae and why does it matter?
Mycoplasma pneumoniae is a type of bacteria that causes respiratory infections, most commonly walking pneumonia. Unlike other bacteria, it lacks a cell wall, which makes it resistant to common antibiotics like penicillin. It spreads through respiratory droplets and can cause prolonged symptoms that last weeks to months if untreated, making proper diagnosis and targeted antibiotic treatment important.
What does a positive IgM result mean?
A positive IgM result indicates you have a current or very recent Mycoplasma pneumoniae infection, as IgM antibodies are the first type your immune system produces when fighting an active infection. This typically appears within the first week of symptoms and suggests you may benefit from antibiotic treatment. Your doctor may prescribe macrolide antibiotics like azithromycin or tetracyclines like doxycycline, which are effective against Mycoplasma.
