Infection (Definition)

Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more

Have IgG and IgM for CMV but PCR not detected. Pos rmsf IgM neg igg. Bands in CSF mri/white matter foci. Many symptoms possible ms.. No real answers?

Uncertainty: I am unclear as to what is really going on. Appears that you have immune activity in the central nervous system. You have some cross-reactivity in the serum for CMV and rickettsial infection. Don't think that need to add another disease to the picture. Best to discuss with your doctor or get a second opinion from another specialist. ...Read more

EBV Capsid IGG and EBNA IGG was positive, but IGM index negative. Doc said I had a past recent EBV infection. Is this true? Retest? Still feel sick

EBV Capsid IGG and EBNA IGG was positive, but  IGM index  negative. Doc said I had a past recent EBV infection. Is this true? Retest? Still feel sick

EBV INFECTION: The lab results are indicative of past exposure. A recent exposure would have + IGM. if you recheck also have MONOSPOT and CMV TITERS checked to be complete. Both CMV and EBV cause Mononucleosis. ...Read more

I had CMV antibody IgG blood test, is there a seperate test for igm?

I had CMV antibody IgG blood test, is there a seperate test for igm?

CMV: You can order separate IgG and IgM for CMV. I have to wonder if the lab you use does the IgG first and if negative runs the IgM as a positive IgG would usually mean past exposure. However, I would call the ordering physicians/CNMs office and confirm if they ordered both IgG and IgM. ...Read more

Does a negative hep b surface antibody test mean I have no current infection?

Does a negative hep b surface antibody test mean I have no current infection?

No: There is a lag time between when a person becomes infected with a virus (or other invader) and when antibodies begin to appear in the blood. So you can be ifected without any antibody evidence of infection early in any disease. ...Read more

Igg of 156 for toxoplasmosis, IgM was negative. Active or distant infection? Since IgG is so high, could the IgM just not be + yet? 11 weeks preg.

Distant: With a high igg and a negative igm this is supportive of exposure in the remote past. Igm would not turn positive after igg is already elevated. That said, it's not clear from your question why your toxo titers were tested in the first place, and i suggest you discuss the results with the provider who ordered them to be clear. ...Read more

Only indicates you..: Indicates you've had mono. The mono virus is permanently inserted into your b-lymphocytes and hepatocytes (liver tissue) forever! legacy of the "kissing disease! however, you did not specify your titer of "early antigen, " which can indicate chronic mono. See if this test was done! but form the data you present, nothing is abnormal and indicates you have had mono in the past! ...Read more

My 3yrs baby dengu NS1or IGg negative but IGm show wekly positive and plates 169000 what mean this reports?

My  3yrs baby dengu NS1or IGg negative but IGm show wekly positive and plates 169000 what mean this reports?

Platelet count is: normal. This is a good sign. Negative NS1 usually means that whatever your baby's illness is, Dengue is not likely. Negative IgG means your baby hasn't had Dengue before. A weakly (+) IgM could be early Dengue, but it could be something else. The most important thing is that your baby gets proper supportive care. Example: if he's not drinking, he may need replacement fluids. Namaste. ...Read more

Recheck: With viral infections platelets can drop down, its usually reversible and once your body fights back the infection they go back to normal, i advise you to recheck them again in a week just to make sure they are going back to normal. ...Read more

ABO Type&Screen, does "negative" antibodies mean NO antibodies at all or no UNexpected antibodies for the reported blood type?

ABO Type&Screen, does "negative" antibodies mean NO antibodies at all or no UNexpected antibodies for the reported blood type?

No unexpected ones: It means no antibodies against the red cells of the cross match. E.g., if you have type A blood, you would have anti-B antibodies as a matter of course. The potential donor blood is type A, but you also have no antibodies against any of the other antigens (outside of ABO system) which mY be found on red blood cells. ...Read more

Can LGV Chlamydia be detected by the Quest lab antibody test that checks for L2 igM igA igG for C. Trachamatis. Is this accur. For LGV at 5 months. ?

Can LGV Chlamydia  be detected by the Quest lab antibody  test that checks for L2 igM igA igG for C. Trachamatis. Is this accur. For LGV at 5 months. ?

Accurate, but why?: Lymphogranuloma venereum (LGV) is caused primarily by a particular type of chlamydia, called L2. The Quest test is very accurate; a negative result 5 months after exposure or possible symptoms is strong evidence against LGV. But why be tested? Symptoms? Partner w/ possible LGV? In the US, LGV occurs almost entirely in gay men; there have been few or no cases in women for the past half century. ...Read more

I got 3 HepB vacc. L8r a surface antigen & core antibody test both showed:non-reactive.B/C no antibodies present does this mean the vacc didn't take?

I got 3 HepB vacc. L8r a surface antigen & core antibody test both showed:non-reactive.B/C no antibodies present does this mean the vacc didn't take?

That's good: Hepatitis B surface antigen negative usually means a person is not carrying the virus. Hepatitis B core antibody negative usually means a person did not catch the virus in the past. Neither test is about the vaccine. There usually is a third test, if needed, to see if a person is immune due to taking the vaccine: Hepatitis B surface antibody. ...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
