Reactivated EBV 9 months after first infection. Could i be immunodeficient? Antibody count: 65 ab VCA igm; 53 ea ab igg; 431 ab VCA igg; 289 ebna igg.

Reactivated EBV 9 months after first infection. Could i be immunodeficient? Antibody count: 65 ab VCA igm; 53 ea ab igg; 431 ab VCA igg; 289 ebna igg.

No: Unfortunately ebv stays alive forever in one's lymphocytes and can get activated easily in susceptible people without known immunodeficiency. However you may call that an immunodeficiency given that all people have been infected with it yet only few would have recurrent ebv problem. ...Read more

EBV early antigen Ab, IgG <9; EBV Eb, VcA, IgG >600; EBV nuclear antigen Ab IgG 108. Diagnossed with CAEBV infection. Does this sound right to you?

Maybe.: The profile is of a past infection. I am not sure if it can be diagnosed just by symptoms and evidence of past infection. I think you would need the second criteria of diagnosis which is DNA of EBV in peripheral tissue or blood detectable through PCR test with a low anti-EA. Have other diagnoses like Lyme's been tested for? ID specialist. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3245398/ ...Read more

Ebv panel. Ebv nuc antigen igg=157, early ag igg=12.7, EBV VCA igg=112, EBV VCA igm=10.6. Please explain. Concerned about spleen. Symp=fatigue/fog?

Ebv panel. Ebv nuc antigen  igg=157, early ag igg=12.7, EBV VCA igg=112, EBV VCA igm=10.6.  Please explain.  Concerned about spleen. Symp=fatigue/fog?

? Active infection: It's impossible for me to answer with certainty since i don't know the normal ranges your lab uses. If early ag & vca igm are elevated above normal this indicates active ebv infection.I don't know if it is acute or chronic without knowing your history. If chronic i see that as a sign of poor immune function.Immune-boosting herbs/supplements & IV vit c drips may help, but find why immunity is poor. ...Read more

Elevated EBV ab VCA IgG <8 and EBV nucleaer antigen ab IgG test 4.2. & anti-dna(ss)igg ab qn ( 119)& c react protien(5.6) what are implications?

Elevated EBV ab VCA IgG <8 and EBV nucleaer antigen  ab IgG test 4.2. & anti-dna(ss)igg ab qn ( 119)& c react protien(5.6)  what are implications?

Nothing.: Ebv antibodies indicate you had a previous infection, but not active. The c-reactive protein needs a units indicator - that is either normal or somewhat elevated. The anti ss dna is extremely nonspecific and very rarely indicated; I have no idea why that was ordered, discuss with your doctor. ...Read more

Hiv ab,1/2, eia with relx result repeatedly reactive. HIV 1/2ab differentiation w/refl hiv1 antibody negative hiv2 antibody negative. pos or neg hiv?

It depends: In a situation like this you have one positive test and one negative test. The lab should run a tie-breaker test (HIV RNA) to give you a real answer. Also, the first test may be an older test 2nd or 3rd generation) instead of the latest 4th generation) test. It also depends on if you have flu-Like symptoms. Seek help from a specialist in HIV who can help you understand. ...Read more

What happens if "h. pylori IgG antibodies serum by ELISA positive"?

What happens if "h. pylori IgG antibodies serum by ELISA positive"?

H. pylori infection: .. which causes gastritis with symptoms of early satiety, abdominal pain, heartburn. If you are symptomatic, then you will need the treatment. If you are not symptomatic or have responded to treatment already, then your test result indicates ongoing antibody production (normal immune response to previous infection) and no treatment is required. Good luck! ...Read more

Had EBV test came back EBV nuc IgG ser qi eia positive and EBV vac IgG eia postive. Ebv capsid IgM eia negative. I'm so tired what do this mean?

Had EBV test came back EBV nuc IgG ser qi eia positive and EBV vac IgG eia postive. Ebv capsid IgM eia negative. I'm so tired what do this mean?

Makes perfect sense: Igm antibodies rise only during the actual, acute infection. They then fade away and are replaced by the various igg antibodies, which are the ones that provide lifetime protection against the same strain of the virus. So your numbers are consistent with the fact you had mono years ago. There is no igm, and positive igg levels. So you are immune and do not currently have mono. ...Read more

What causes high IgG antibodies but negative igm?

What causes high IgG antibodies but negative igm?

Immunity: Igm is the first line of defense and reacts first, then long term immunity is provided by igg. So a positive igg and negative igm to something means an old exposure. ...Read more

What would cause a high positive ANA (1:640) speckled, nucleolar with a low positive smooth muscle antibody (1:40) but negative SS-A, SS-B, anti-Smith, RNP, SCL-70, Anti Jo antibodies? Liver disease?

What would cause a high positive ANA (1:640) speckled, nucleolar with a low positive smooth muscle antibody (1:40) but negative SS-A, SS-B, anti-Smith, RNP, SCL-70, Anti Jo antibodies? Liver disease?

Probably normal: Many people have a positive ANA without being sick. If you also have elevated liver enzymes, a workup for autoimmune hepatitis may be continued, but if there's nothing to suggest a liver problem biochemically, I'd not be in a hurry to diagnose despite anti-smooth-muscle. ANA means nothing apart from the clinical picture. Best wishes. ...Read more

Ebvab VCA IgM <36 (range 0-35.9), ebvearly antigenab IgG 37 (0-8.9), ebvab VCA IgG >600 (0-17.9), EBV nuclearantigenab IgG 409 (0-17.9) mono? No mono?

Ebvab VCA IgM <36 (range 0-35.9), ebvearly antigenab IgG 37 (0-8.9), ebvab VCA IgG >600 (0-17.9), EBV nuclearantigenab IgG 409 (0-17.9) mono? No mono?

You had mono...: Your mono-like symptoms likely prompted the testing- i hope you are starting to feel a little better. Testing for different antibodies (igm and igg) against ebv, requires careful interpretation. In early phases of infection, the igm level peaks first followed by a decline; levels of igg peak afterwards, and may remain elevated for quite a while. ...Read more

Positif ANA IF, Anti-B2 glicoprotein igM, anti-CMV igG, Lupus Anticoagulants, history of DVT. Dr suspect Antiphospholipid Syndrome (APS). Possible?

POSSIBLE: Your lab outcomes plus the prior DVT, seem consistent, but other labs may further assist such as changes in PTT. Might get additional opinion to confirm your diagnosis, and exclude other problems, but certainly antiphospholipid antibody syndrome seems high on list. ...Read more

I've been sick for about 3 weeks, mostly fatigue. My EBV levels are VCA IgG 153, VCA IgM <10, early AG IgG 25.7, nuclear antigen IgG 158. Any ideas?

I've been sick for about 3 weeks, mostly fatigue. My EBV levels are VCA IgG 153, VCA IgM <10, early AG IgG 25.7, nuclear antigen IgG 158. Any ideas?

No idea: First you would need to give us more details on the sickness other than just fatigue. The tests you have had are not helpful in making a diagnosis. I would recommend that you consult an internist to get a thorough workup since there are many causes for fatigue= both physiologic and psychologic. ...Read more

Where are antibodies produced in the body?

From immune B cells: Antibodies, also called immunoglobulins or gamma-globulins, are made in a type of white blood cell called B-cells. They are in the blood stream, lymph nodes and in the bone marrow. We have 5 different types of antibodies: IgM (first responder), IgG (good long term immunity), IgA (in the mucous lining-tears, saliva, respiratory tract and intestinal tract), IgE (allergic antibody) and IgD (unknown) ...Read more
