Types Of Antigen Antibody Reaction
It depends: Generally IgM is the first seen in the blood stream. ...Read more
What makes immune cells only attack one type of antigen, as opposed to multiple different antigens?
It's complicated: When immune cells come into contact with a foreign substance (called an antigen), they engulf that substance and either start making antibodies to it or activate other immune cells to come into the area to fight off the foreign invader. Antigens are fairly specific so antibodies that form are also fairly specific. Sometimes mistakes occur however. Here's a link to more: http://bit.ly/1uy9lyG ...Read more
Does a monoclonal antibody reactive with the o139 antigen of e.Coli would cross react with v.Cholera o139?
Apparently not.: This does not seem likely because first that the v cholera is usually found in india and bangladesh while ecoli is usually in the U.S., mexico, and south america. Second, the mechanisms are different because the genes for toxicity on the e coli strains are not present in the v cholera. Third, there seems to be no information on any cross reaction of these two o 139 strains. ...Read moreSee 1 more doctor answer
Yes, but complicated: Trying to tell whether a person has HIV-1, HIV-2, or both, can get complicated. If a person has high risk exposures or has symptoms, he can see an HIV Infectious Disease doctor and trust the advice, but follow-up as instructed. There are many different tests (usually by various manufacturers) in different parts of the world, which happen to have different prevalences for various HIV strains. ...Read moreSee 1 more doctor answer
Hiv 1/2 blood analysis:
-antibodies and p24 antigen (chemiluminescence): reactive-2, 741
- IgG antibodies (enzyme immunoassay):nonreactive
in this case, is HIV infection accurate?
ABO blood groups: Not sure i understand your question. Abo antigens are glycoproteins (sugar-like molecules) found on the surface of red cells. There are 4 common types: groups a, b, ab, and o. People with type a blood have antibodies against b. Those with type b have antibodies against a. Those with type ab don't have any antibodies at all, while those with type o have antibodies against both a and b. ...Read more
Usually IgM: Normally occuring antibodies to ABO antigens are of the IgM type. Igg antibodies can form on stimulation. ...Read more
Hi Doctor, I did blood testing of Liver. the result are Anitibody anti HBe or Aniticorp anti HBe : Reaction Positive & Antigene HBe Reaction Negative.
Hepatitis B tests: An antibody means that your body reacted to something and tried to fight it off. That's your immune system doing what it's supposed to. An antigen is something like a piece of virus that shouldn't be there. Your test report shows you were exposed to Hepatitis B but luckily your body fought it off. This HepBe test helps prove if you developed immunity from natural infection or from the vaccine. ...Read more
Cells vs, animals: A monoclonal antibody is produced by in-vitro manipulation by expoanding a single cell making a desired antibody. Polyclonal antibodies are usually derived from immunizing an animal and colletcting its blood/serum containing the antibody. Polyclonal antibodies are a mixture of a large number of different cells. ...Read more
On the cell surface.: Ige mediated allergic reactions involve 2 ige antibodies directed against the same allergens in close proximetry on the surface of mast cells or basophils. The antibody then fits in between the 2 ige antibodies. That activates the cell to release mediators (chemicals) that directly or indirectly by activating other cells resulting in allergy symptoms. The ige antibodies themselves do'nt cross link. ...Read more
HIV screening: An ELISA is often done as an initial HIV screening test. It is designed to have high sensitivity for most types of HIV in the gene real population, but does have some false positives. That being said, there are some types of HIV, e.g. type O, that are unusual outside of Cameroon or West Africa, but are not recognized by usual antibody tests. Check with an I.D. specialist for your area and test. ...Read more
hepatitis b surface antigen reactive and hepatitis b surface antibody nonreactive and core antibody total reactive and HBV DNA detected sir plz reply?
You carry hep B: I am assuming you feel well and this was a surprise finding. There are millions of people like yourself. You will require lifelong health care for it unless / until a means of eradicating it is found. You pose no danger to a partner who is immunized. ...Read more
Immunifixation identifies m spike as IGg Kappa polyclonal gamma globulin to consist mainly of IGg Kappa n Lamda with fair amounts of Iga means what?
?? Chronic Infection: M spike of polyclonal IgG (kappa & lambda) globulin mostly suggest chronic infectious or inflammatory process & rarely hematologic malignancies. You need a complete work up for ch. liver disease, hepatitis B/C, ch.bacterial, viral & fungal infection, HIV, autoimmune diseases & if negative then evaluate for hematological disorder. CHECK FOR Ch. INFECTION & HEPATITIS. Update me with your result. ...Read more
Infection is active: If you are surface antigen postive = protein on the surface of the virus is in its active form which is still floating in your blood and indicates active/on going infectious state. This protein triggers body to produce antibody which can help rid off the infection or preventing it as in case of hepb vaccines. In your case, no antibody or not enough to rid of the antigen. Consult doc. Good luck. ...Read more
Hepatitis AG & AB: The most common forms are hepa, hepb, and hepc. When testing for these forms you will do a blood test that will show antigens (ag) and/or antibodies (ab) for hepatitis. Hepa and hepc only have one ag which will result in one ab to fight if off. Hepb has both a surface ag (hbsag) and e ag (hbeag) resulting in hbsab, hbeab and hbcab (with results from infection of hepb). ...Read moreSee 1 more doctor answer
