Under what conditions might a person with Rh-blood develop Rh antibodies?
If they are transfused with Rh+ Blood which doesn't cause huge issues the first time, they will develop Rh antibodies. Also, if an Rh- woman is having an Rh+ child, during gestation and birth the blood can 'mix' and antibodies can form.
Active. Foreign microbes, or parts of microbes, are introduced to the body and the immune system reacts and produces antibodies. The antibodies were made in reaction to a foreign body introduced into the body, so it's active. Passive is when the antibodies are given directly to the person, such as from mother to child in pregnancy.
Yes the test is reliable but, most HIV tests are antibody tests that measure the antibodies your body makes against HIV. It can take some time for the immune system to produce enough antibodies for the antibody test to detect, and this time period can vary from person to person. This time period is commonly referred to as the "window period." Most people will develop detectable antibodies within 2 to 8 weeks (the average is…
It is known that if a person develops cow pox and recovers and then is exposed to smallpox and he or she is less likely to develop smallpox why?
This is because the two types of pox are related. Someone exposed to cowpox will develop antibodies to the cowpox. These antibodies will help fight against small pox. This phenomenon was observed by Edward Jenner, who used it to create a smallpox vaccine. (The word "vaccine" is related to the Latin word for "cow".)
When a person contracts HIV, their body releases certain antibodies to fight that infection. As such, if those antibodies are found in a person, then that individual has HIV. These antibodies can be detected through a simple examination of oral fluids or a blood sample. If you are found to have these antibodies, then you are seropositive.
The major concern with HIV testing that is inaccurate is when people test too early. In order for an HIV test to be accurate, there have to be enough antibodies present for the test to pick up. If a person tests too soon after infection, the body may not have had time to develop antibodies which can be measured. In these cases, a test will return a negative result, when in fact the person is…
After being exposed to HIV how long may it take for HIV antibodies to be found in your blood if you are infected?
If a person is blood type A then they will have red blood cell antigens of A and plasma antibodies (agglutinins) called Anti-B. If a person is Type B then they will have B antigens and Anti-A antibodies. If a person is Type AB they will have both A and B antigens, but no plasma antibodies. If a person is type O then they will have no red blood cell antigens but they will have…
Immunisation is the process of inoculating a person with a weak form of an infection. Their body then prepares antibodies and heals itself; those antibodies remain so if the disease strikes again it is ready to defend itself. Diabetes etc. cannot be caught like a cold as they are developed conditions that occur from changes to a person's organs' operation.
No,the person who has once caught measles has the antibodies against measles viruses. When a person has caught measles th T type lymphocytes detect the type of virus and then the B type lymphocytes produce antibodies for the viruses of maesles.Antibodies stick with these viruses and destroy them. This person can not get measles again in life because the antibodies against measeles are already produced for prevntion by catching measles once. These antibodies are memory…
No specific disease results from lack of physical activities. But diseases are different from conditions. Many conditions can result from lack of physical activities. Some conditions include: general deconditioning obesity loss of muscle mass contractures foot drop From some conditions a person can develop diseases, such as obesity contributing to heart disease.
Acquired immunity can be gained by the use of vaccinations either from your primary care giver or your local health department. Passive immunity can be acquired from exposure to someone who has the disease, in which case the person can often develop a light case of the disease, which would cause one's body to develop antibodies against the disease, thus achieving the same effects as the vaccination.
Yes. If you transfuse type B blood into a type A person there will be agglutination because the type A person naturally makes anti-B antibodies. The converse is also true. If you transfuse type A blood into a type B person there will be agglutination because the type B person naturally makes anti-A antibodies.
