if exposed to measles and blood is tested & shows high level of IgM anitibodis to rubella virus but few IgG?

First, the rubeola virus causes measels. Rubella is German measels, which is a completely different virus. This confusion often arises since the measels vaccine is given as an MMR injection. MMR stands for Measels, Mumps and Rubella, and this lets you be protected from all three with a single shot.\n\nHigh levels of IgM antibodies are a sign of recent or current infection. If a person tests strongly positive for anti-rubella IgM then yes, they have the disease (or at least have had it within the last several weeks). Over time the level of IgM will drop and the level of IgG will rise. In the case of rubella, it takes about 6 weeks for the IgM to disappear.\n\nOn the other hand, if someone has only IgG antibodies they either had a previous infection or have received vaccine for that virus.\n\nA great reference for medical tests is:\n\nMosby's Manual of Diagnostic and Laboratory Tests by Kathleen and Timothy Pagana.

If you Are ONLY HBsAb+, then Immune and No Chronic Infection.  But you Said HBsAg+, Possibly Primary or Chronic Infection, Inquire of your Dr. About Meds. for this.

I think you mean 'isotype.'\n\nDuring a primary infection, IgM appears after about 7 days, peaks around 10 days, and disappears around 15 days.  IgG appears around 10 days, peaks around 21 days, and disappears around 35 days.\n\nDuring a secondary infection (something the person has already been exposed to), IgM and IgG both appear within about 3 days. IgM peaks around 8 days and disappears after about 15 days.  IgG peaks around 21 days and will tend to stick around for a very long time.\n\nThese numbers are rough ideas, but the time courses will vary with different antigens, the amount of antigen, and the route of exposure.

You could also be anemic.  Have a blood test done and check that out.

compared to other immunoglobulins IgG is small enough to move across the tranplacental barrier.  The major antibody for antitoxins, viruses and bacteria it can provide the baby passive immunity.

well that could mean that the ebv virus is dormant in your system,meaning you already had it. The mono count will always be high. As far as the antibodies more tests can be done to determine if there is a problemwith the antibodies.

The IgG test is looking for antibodies in the blood to HSV-2.  It does take time for the antibodies to develop following the first infection with the virus. I do not know if it 6-8wks, I am assuming that this is what the doctor told her.  It is possible that she was negative previously.  Example: a woman presents with her first outbreak of genital herpes.  culture of the genital blisters confirms the presence of herpes, but her blood test does not show any IgG antibodies yet, but will in the future.  So, if your friend was known to be negative HSV-2 IgG around 6-8 wks ago and now is positive it is a recent infection. I would be wary of using her services.  most herpes infections are transmitted when no lesions are present and condoms do not protect from herpes.

The most reliable lab test for HFMD is cell culture which can take 1-2 months (HFMD usually does not even last 2 months).   A rapid test would be beneficial, especially in areas experiencing epidemic outbreaks, that don't have sufficient numbers of physicians to see all the cases quickly.  This is the reason there is research into using the faster microneutralization test to diagnose HFMD, but right now it is not acurate enough.  \n\nTo read about microneutralization in detecting HFMD\nSee:\nhttp://www.pubmedcentral.gov/articlerender.fcgi?artid=120643\n(see materials & methods section)\nhttp://www.ijppediatricsindia.org/article.asp?issn=0019-5456;year=2005;volume=72;issue=1;spage=17;epage=21;aulast=Sasidharan\n\n\nYou should not give children with a fever aspirin, because it can cause a rare but fatal liver dysfunction caled Reye Syndrome\n\n\nTo read more about Reye's Syndrome\nSee:\nhttp://www.patient.co.uk/showdoc/40001425/\nhttp://www.healthy.net/scr/HealthHint.asp?Id=73\n\n\nTo read more about treating fevers in kids\nSee:\nhttp://www.ds-health.com/fever.htm\n\nHand Foot & Mouth disease affects mainly children under 10, because they are least immune to it and most exposed.  HFMD is spread by infected nose & throat discharges & feces. (these stay infectious for weeks,  even ater the patient that produced them has recovered)   Kids may not wash their hands much and often touch filthy things, including their own spit & mud.  Once someone recovers from HFMD they are usually immune, for several decades.  \n\nTo read more about Hand Foot & Mouth Disease\nSee:\nhttp://www.ibufamily.org/coxsacki.html\nhttp://www.ezyhealth.com/ezyhealth/medreslib/medconds/MedCondsDetail.cfm?islogin=false&ObjID=8B1212B4-674E-11D4-8DE900508B69ABDA\nhttp://www.webmd.com/hw/parenting_news/ty6231.asp?printing=true\nhttp://www.cdc.gov/ncidod/dvrd/revb/enterovirus/hfhf.htm\nhttp://www.healthtouch.com/bin/EContent_HT/cnoteShowLfts.asp?fname=07070&title=HAND%2C+FOOT%2C+AND+MOUTH+DISEASE+IN+CHILDREN+&cid=HTHLTH\nhttp://www.babycenter.com/refcap/toddler/toddlerills/todrash/11433.html

Yes you can take blood tests. You may have to get a referal from your regular doctor, but you should see a allergist. They take little samples of lots of foods and other things and prick it into your arms (both arms) and which evers gets swollen and itchy after 10-15 minutes, you are allergic to. It is very cool, i have gotten it down twice.

The IgM will persist until the antigen is removed. The presence of IgM is usually taken to mean that the infection is still active. IgM usually appear 1-2 weeks after initial exposure, while IgG appear 3-4 weeks after initial exposure.\n\nThe exact numbers may vary a little, but this is what I remember.

Several possibilities include hepatitis B and C.  You'd probably know if you had these.  Another possibility is cytomegalovirus (CMV) -- it is a virus that is present in a large portion of the population.  It is dormant and has no effect until the immune system goes down.  Sometimes the plasma is given to people with poor immunity and thus needs to be CMV negative.  The people who rejected your plasma should tell you why.  Good luck!

My son had Fifths disease before.  Its also known as parvovirus B19 and "slapped cheek" disease.  Its actually not a disease at all --its a virus-- and once the child has the rash, it is no longer contagious.  They're most contagious right before the rash appears and the rash can last about 1 to 2 weeks.  Other than the rash there are usually no other symptoms at all although its possible to have fever, aches and itching.  My son didn't have any of that. Its not really treatable so you just wait it out until the rash goes away.  The child can go to school with the rash without passing it on to anyone else.

most doctors can tell just by looking at the type of rash you have.  But, if they cant they will probably take a blood sample

I think that there was a common vaccine given to kids at their school for mumps,rubeola and chicken pox.After that time the powers that be decided it was basically eraticated at large and they changed it to be done elsewhere to the parents choosing. So, if you are going to be exposed now-you must show your own proof that you had your shots.

Hello,\n\nAn inconclusive test doesn't mean that your brother is hiv+. I work with an abundance of doctors and immunologsts and this is what they keep on telling me...\n\nIt could be a cold, cold is a virus which your body can produce anti-bodies \n\nanother auto-immune disease like hepatitis, which could lead to an inconclusive test.\n\nHe could be anemic ..or something of that sort....\n\nthe test could have been mixed up or broken or damamged something could have happened that your brother isn't aware of...\n\ni know this, that some people that test inconclusive test negative....\n\ni am being hnest it doesn't mean he is positive...another thing if he only had an antibody test wow that is a long wait....some people opt for the p24 which detectts antigens b4 appearance of antibodies or pcr which tests for the actual dna of the virus...\n\nThis all depends on what test he had done, for the so-called professional to tell your brother he was inconclusive

If I remember clearly, selective immunoglobulin M deficiency (SIgMD) is a rare form of dysgammaglobulinemia characterized by an isolated low level of serum immunoglobulin M (IgM). For clinical diagnosis of this condition, IgM concentrations are usually found to vary from 40 mg/dL to undetectably low levels, where the (normal) reference range 45-150 mg/dL. \n\nSo your IgM will basically have to fall anywhere below 40mg/dL.
