What's this test for?

This test is ideal if you're experiencing extreme fatigue, sore throat, swollen glands, or fever that won't go away. These are classic signs of infectious mononucleosis, often called "mono" or the "kissing disease," which is caused by the Epstein-Barr virus. It helps confirm whether these symptoms are due to mono so you know how to move forward.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a positive or negative heterophile antibody result means. If positive, the report will outline simple next steps like resting, staying hydrated, and avoiding contact sports until you recover, since an enlarged spleen can be a risk. You can download the standard lab report anytime from your account, and if you get tested again later, you can track your results over time using the trends feature.

Who should consider this test?

Anyone with ongoing fatigue, sore throat, swollen lymph nodes, or low fever lasting more than a week should consider this test, especially teens and young adults who are most commonly affected by mono. It's also useful if you've been in close contact with someone diagnosed with mono. Getting tested early helps rule out other illnesses with similar symptoms, like strep throat or the flu.

What symptoms indicate I may need this test?
Common symptoms include extreme tiredness that doesn't improve with rest, a sore throat that doesn't respond to typical remedies, swollen glands in the neck, fever, headache, and body aches. Some people also notice a swollen spleen or mild rash. If these symptoms last longer than a week or two, it may be time to check for mono.
When will I get my results?
Results are typically ready within about 7 days after your sample is collected at the lab. You'll get a notification as soon as your results are posted to your secure online account. This gives you a clear timeline so you're not left wondering while dealing with symptoms.
How can I naturally support recovery from mono?
Rest is the most important thing you can do, since your body needs energy to fight off the virus. Drink plenty of fluids, eat nutrient-rich foods, and avoid strenuous activity or contact sports for several weeks to protect your spleen. Over-the-counter pain relievers can help with sore throat and body aches, but check with a pharmacist before combining medications.
What does a positive result mean?
A positive heterophile antibody result means your immune system has produced antibodies commonly seen with mono, suggesting an active or recent Epstein-Barr virus infection. This typically means you should rest and limit physical activity, especially contact sports, for several weeks to avoid complications like a ruptured spleen. Most people recover fully within two to four weeks with rest and self-care.
What does a negative result mean?
A negative result means heterophile antibodies weren't detected, which could mean you don't have mono, or it could be too early in the illness for antibodies to show up since they may not appear until the fourth day of symptoms. If your symptoms continue, retesting after a few more days may give a more accurate result. Your symptoms could also be from another virus or infection that needs a different kind of test.
How often should I retest?
If you test negative but still have symptoms, retesting about a week later is a reasonable next step since antibodies take time to develop. Most people don't need repeat testing once they've had a confirmed positive result and have recovered. If symptoms return or worsen, that's a sign to check in again.
What should I do if my results are abnormal?
If your result is positive, focus on rest, hydration, and avoiding activities that could strain your spleen, like contact sports or heavy lifting, for at least a few weeks. Watch for warning signs like severe abdominal pain, difficulty breathing, or a high fever that doesn't improve, and seek medical care right away if these occur. Otherwise, most cases of mono resolve on their own with time and rest.

What this means

A negative result means heterophile antibodies weren't detected in your blood sample. This usually suggests you don't currently have infectious mononucleosis, though it's possible to test negative early in the illness before antibodies develop.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
