Can mono still show up on a blood test if your body has fought it all off? If so how long after can it

Can mono still show up on a blood test if your body has fought it all off?  If so how long after can it

May be life long: Mono is not a specific infection and similar symptoms can occur with more than one virus. EBV is the usual cause and once a person is infected, the virus stays in the body for the rest of the life and antibodies to EBV can be detected for years after the initial infection. The so call mono-spot test may become negative in a few months after infection. ...Read more

It possible to be relapsing with mono and not show any obvious symptoms? Blood tests would be abnormal?

It possible to be relapsing with mono and not show any obvious symptoms? Blood tests would be abnormal?

Not likely relapse.: Infectious mononucleosis has 2 big causes. Cytomegalovirus (cmv), and epstein-barr virus (ebv). CMV has high fevers with chills, fatigue, and malaise. The main lab finding is peripheral lymphocytosis with over 10% atypical lymphocytes on blood smear. Ebv has pharyngitis and cervical lymphadenopathy. In both cases, infants may be asymptomatic or show mild diseaese, though CMV has side effects. ...Read more

For how long after I have mono will my blood count of monocytes be elevated?

For how long after I have mono will my blood count of monocytes be elevated?

Not important: Is your diagnosis of infectious mono correct? Because high monocytes can represent a variety of other diseases also. If you had lab proven infectious mono, the monocytes stay up for 4-8 weeks but that is not important. If you are worried re infecting others, the + igm of ebv is what determines if you can infect someone else and that may stay up up to 18 months. ...Read more

I was diagnosed with mono. Took a blood test recently and it had passed. Now I have an enlarged liver after the mono is gone, from what and how long?

I was diagnosed with mono. Took a blood test recently and it had passed. Now I have an enlarged liver after the mono is gone, from what and how long?

Can take a while: Mono is caused by 2 viruses (epstein-barr more often, cytomegalovirus-less common). Same presentation and clinical course. Usually about 2 weeks with fatigue, sore throat, swollen glands; either can cause liver inflammation (w/ or w/o enlargement), enlarged spleen. Can take up to 6 months for recovery. Follow up labs. No alcohol, eat right; no contact sports if enlarged liver/spleen, . ...Read more

February I had bloodwork tested for Mono @ hospital. Do they do full blood counts? if I had a thyroid problem would it show on that test & notify me?

Hard to say: One mono test is quite specific and doesn't look for anything else.The lab is unlikely to do any test that is not ordered, so you must ask the personnel involved to see if anything else was done. ...Read more

Would having mono 5 years ago cause a blood test to show possibility of autoimmune liver disease today?

Would having mono 5 years ago cause a blood test to show possibility of autoimmune liver disease today?

No: In fact, if you have labs suggesting autoimmune hepatitis, i would be very concerned and would be hammering away at my doctor for all the information i could get. It is possible that an old hepatitis (infectious mono, hepatitis a) may trigger autoimmune hepatitis -- the jury's out on this, but it's moot. Please comply with your diagnosis and if needed treatment, and enjoy a long healthy life. ...Read more

Sick for 2 weeks now. Throat so bad appeared to be mono (tests show it's not). Blood count normal. What's wrong?

Sick for 2 weeks now. Throat so bad appeared to be mono (tests show it's not). Blood count normal. What's wrong?

Ask your doctor: There are many causes of a sore throat. If you have been tested for mononucleosis you have seen a doctor, so go ask that doctor what he/she thinks you have. Perhaps you have sinusitis and allergies with post-nasal drip. Perhaps you have some other kind of infection. Only your doctor (or another who sees you) can figure this out. ...Read more

I've had a low grade fever for 4 weeks. Urinalysis is positive for bilirubin, protein and blood. Cbc shows mono%13. Any idea what all of that means?

I've had a low grade fever for 4 weeks. Urinalysis is positive for bilirubin, protein and blood. Cbc shows mono%13. Any idea what all of that means?

Possibly: The best thing you can do here is to see an infectious diseases expert. You have what is called fever of undetermined origin, and this needs a detailed evaluation, not more antibiotics. Blood in urine is tuberculosis or cancer until proven otherwise. Go see an id doctor now, and good luck, . ...Read more

If I have a blood test tomorrow morning and i smoked marijuana tonight would it show up? Theyre testing hemoglobin, mono, tsh, lyme, cmp, sed rate

If I have a blood test tomorrow morning and i smoked marijuana tonight would it show up? Theyre testing hemoglobin, mono, tsh, lyme, cmp, sed rate

Probably not: Most drug screening tests are urinalysis. Although blood tests can be done they are much more expensive. It sounds like your labs have been ordered to work up specific symptoms, to better help you physician make a clinical diagnosis. I am very skeptical that a thc level would be included in this type of workup. Hopefully you live in a pot legal state.....Otherwise be careful! ...Read more

Mono can present as: Mono is caused by virus's-either Ebstein Barr or Ctomegalo Virus. They both can cause sore throat, fatigue, and cough. if you are still having cough, i would suggest getting that looked at again as there may be other things. Mono can and usually does suppress your immune system which can lead to other bacteria or viruses taking opportunities to flare and cause issues. ...Read more

What is wrong with my sore throat? When can I feel better? I have a painful sore throat. It has lasted 9 days now. I went to the doctor, and she said that my blood test shows it has a lot of qualities of mono, but is not mono, and it is showing a raise

Sore : Sore throat is a fairly common symptom associated with many illnesses. Most of the time it resolves on its own without any other issues. Occasionally it can be due to something more serious that needs treatment. Without examining you myself and sending tests, i cannot tell you what you have. Reasons to seek care again are: - any fever - since it could be strep and you can't tell without an exam/testing - were you tested for strep? - if it lasts longer than 3 or 4 days - any difficulty opening your mouth - unable to swallow - severe pain - bleeding in the throat - redness or swelling on the outside of the neck - any difficulty breathing or noisy breathing 9 days is a long time to have a sore throat and sometimes as the illness goes along, clues as to what is causing your pain can become more apparent. Give your doctor another call or consider seeing an ear, nose and throat specialist. In the meantime, taking Ibuprofen or Acetaminophen for pain, drinking plenty of fluids such as hot tea/broth or cold liquids and a spoonful of honey can help. ...Read more

Infected in the past: A titer greater than 1 to 10 (1:10) usually means that you have been infected with ebv at some time.

A titer of 1:320 or greater means that you have an active ebv infection (mononucleosis). Igm is present. Igg may also be present but may mean that you have been exposed to ebv i. ...Read more

Confusing question: Mono often will have a mild hepatitis as one of it's many symptoms. However, this has nothing to do with the other causes of hepatitis (a, b, c, etc). If you feel you have been exposed to one of those illnesses or have symptoms your pcp can check it out. ...Read more
