No HIV antibodies and no HIV means same in HIV screening immunology test?

No, your body takes a certain amount of time to produce antibodies to counter act a pathogen. Therefore you can have HIV but not have antibodies. This difference in time is called the 'Window Period' which averages 28 days, but can be as long as 3 months.

What are monospecific Polyclonal Antibodies?
Monospecific Polyclonal antibodies are produced by not just a common germ cell like monoclonal antibodies, but from other products. Monospecific antibodies have affinity for the same antigen.
Are antibodies and immunoglobulins the same thing?
yes they are interchangeable
What is the advantage of using monoclonal antibodies?
A single clone, ie a bunch of identical antibodies. As opposed to polyclonal antibodies, which are different clones even though they bind the same antigen.
Is screening effect the same as shielding effect?
YES
Why the A antibody of the AB recipient does not atack the donor A antigen on blood?
Having AB blood means you already have both A and B antigens in your organisms, so you DON'T have the antibodies, the A antigen doesn't affect the AB recipient 'cause it doesn't consider it as foreign (it's the same for the B antigen)
Serological testing is based on the fact that antibodies react specifically with an anigen all bacteria have the same antigens or the human body makes antibodies against bacteria?
AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
Can antibodies be used up?
Antibodies are continuous being produced by activated B cells in your body as a response to your constant exposure to invaders. Antibodies are proteins and synthesized like proteins. Therefore, antibodies will be produced until you die. However, antibodies against a certain type of invaders may disappear when the invaders are eliminated. The ability of the body to respond to the same invaders when they come again lies in the preservation of the B cells that produced these antibodies, not the actual antibodies themselves.
Can you have the same virus more than once?
No. Your body will build antibodies everytime you get a disease. Once your antibodies are built, they will destroy the virus before you can get sick. The reason you stay sick for a little bit is because the antibodies are being created.+
What is immunology in animal practice?
Immunology is the study of the immune system and applies to animals the same way as it does to humans. Animals can have allergies, autoimmune disorders (arthritis, depressed immune systems, etc.) that need to be treated so that the animal can live a more normal life.
What is the role of antibodies in the body response to infection?
Antibodies are basically all the same except for a tip that recognizes the corresponding antigen. When the antibody finds this antigen it locks on and targets the virus.
Is antibodies the same as white blood cells?
No, not even close. White blood cells are cells that circulate in your blood and lymph. B-cells are a type of white blood cell that start producing antibodies when they are shown what the antibody is needed for. For example, if your body has a bacterial infection, other cells 'pick up' debris from these bacterial cells, and 'show' these debris pieces to the B-cells. These B-cells then transform into 'plasma cells', which start producing antibodies specific for that particular bacteria. Antibodies basically 'stick' to any of that same bacteria that they find around your body, acting as a flag, so that your other immune cells can find it and attack it.
What is active vs passive immunity?
Active immunity occurs when an individual is exposed to the disease causing organism, and the immune system produces antibodies to counteract the disease. Future exposure to the same pathogens will stimulate a rapid response from the immune system to produce antibodies. Passive immunity occurs when an individual receives antibodies instead of inducing the immune system to produce antibodies.
