Certain cancers: Cea (carcinoembryonic antigen) can be found at elevated levels in the blood of patients with certain cancers such as colon, lung, breast. It is useful to follow if elevated at the time of diagnosis to correlate with response (if it goes down) to treatment or with relapse (if it becomes elevated again after having gone down to normal levels previously). It may be elevated in other benign conditions. ...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?
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
Is LABCORP "Hepatitis C Virus (HCV) Antibody Verification" test used as was used riba test for ruling out/in false positive hep C HCV antibody results?
Test result was "Hepatitis Surface Antibody - Nonreactive" and "Hepatitis B Surface Antigen - Reactive", "HBS AG Confirmation - Nonconfirm".
Hi please help, hepb surface antigen positive, hep b surface antigen confirmatory negative, antibody negative and anti core negative.What does it mean?
Hepatitis B testing: You should have it rechecked. Hbsag or surface antigen tests are the same, not like in HIV which has screening and confirmatory test. Normally, in the window period after an acute infection, all test for surface antigen or its antibodies are negative except for antibody to core antigen. Hbsag or surface antigen appears right after infection or exposure and disappears in recovery. ...Read more
Antigens are...: An antigen is any substance that causes your immune system to produce antibodies against it. It may be a foreign substance from the environment such as bacteria, viruses, pollen or chemicals. An antigen may also be formed within the body, as with bacterial toxins. ...Read moreSee 1 more doctor answer

"m" antigens: The human body produces particles called antibodies, and these are called either "G" or "M" depending on whether they are in response to old infectious agents called "antigens" or new ones respectively. These antibodies are detectible in the bloodstream and protect against certain illnesses caused by antigens (bacteria, virus or fungal) . In pregnancy it is important to ensure immunity. ...Read more
Depends: This terminology is used more outside the US and means the combination vaccine against diptheria, tetanus and whooping cough (pertussis), given in a series of scheduled doses, followed by boosters.

Food antigens: Antigens are substances, typically proteins, that are recognized by the immune system as foreign to the body. Typically, protective antibodies (igg, IgM or iga) are made to foreign proteins however, some times allergic antibodies (ige) are created. Not all persons have the genetic predisposition to make ige but about 1/3rd of the population is prone to this problem. ...Read moreSee 1 more doctor answer
Super vs mere mortal: A superantigen does not require processing by a middle-man to induce an immune response. Staph enterotoxin is just one of the examples. The regular antigen requires processing and presentation to the lymphocyte in order to induce the immune response. This is just a simple answer to a complex question. ...Read more

An "ID tag": An antigen is a protein of specific shape that can serve to mark or help identify a cell / virus / protein / etc., to the immune system of the body (its white blood cells). The major ones on red blood cells or in vaccines for that matter, are very effective at triggering the body's immune system to attack the foreign object. In blood, a/b/"o" and rh-factor are the main ones + about 2 dozen lesser. ...Read more
The N.I.H. says...: Bacterial superantigens are protein toxins that bind to major histocompatibility complex class ii and t-cell receptors to stimulate large numbers of t-cells. The majority of superantigens are made by the bacteria staph aureus and strep pyogenes, and are the causative agents in toxic shock syndrome, an acute disease caused by the sudden and massive release of t-cell cytokines into the bloodstream. ...Read more

I read that you have millions of B cells. How does one B cell find the right specific antigen it fits to if there's so many of them?
Antigens get held...: Each B cell recognizes only 1 unique antigen. We need > 1 million B cells to ensure most antigens are recognized. Collectively, B cells could likely recognize any organic molecule that could exist. The process does not rely on random encounters. Specialized cells trap and hold antigens where circulating B cells get the chance to recognize them. ...Read more
