Why is there a delay between the time of infection and the first appearance of antibodies in the blood?

The human immune system is an incredibly complex and effective disease fighter/modifier. It is constantly protecting you 24/7. The reason it takes time for the system to respond to an infection is because of the way the system works. When a potentially harmful and new or sufficiently different bacteria or virus invades the body, this triggers a complex response. The short of this is that certain types of white blood cells are 'alerted' of these invaders, at which time they start a process which leads to the manufacturing of antibodies. Lymph nodes are also involved in this process. As with any 'chain of events' process, this takes time. For instance, in the common cold, antibodies are being produced usually within 24-48 hrs, but it takes several more days for the antibodies to start effectively reducing the viral infection. This is why colds last 7-10 days. One other thing about antibodies. When you receive an immunization- a flu shot or tetanus shot for instance, it generally takes about 2 weeks for your immune system to be fully effective. Of course, this can vary from person to person- some will be protected a little sooner, some a little later.

A function of the blood that involves circulating antibodies to combat infection?
One of the function of the blood is to circulate antibodies to combat infection.
You had blood test it showed you have antibodies in your blood?
blood test for antibodies ANA TEST Antibodies are often a sign of an infection best thing to do is talk to your doctor
What does it mean if you don't have antibodies in your blood?
you dont have an infection
How do you diagnosis?
Syphilis is diagnosed with a blood test, which is determined positive if the antibodies to the infection are found in the blood.
The cells capable of fighting bacterial infection in the body are?
it is white blood cells
When a person is suffering from an infection such as strep throat or chicken pox his blood usually shows a significant increase in the number of what?
Antibodies and neutrophils, a type of white blood cell.
What is the role b of the cell?
B-cells are lymphocytes that fight off extracellular infection and call other leukocytes (white blood cells; I.E. T-cells) to the site of infection. they also make antibodies.
What type of white blood cell releases antibodies?
The answer is Lymphocytes. However, they do not RELEASE antibodies. When there is an increase in lymphocytes this indicates a viral infection. Internally, this viral infection is represented as a foreign antigen that could potentially weaken the immune system. Once these foreign antigens are detected this triggers antibodies to form to eliminate the same antigens that created them (the viral infection). These antibodies are what work to fight away the viral infection to return the body to its original state.
Can you urine infection affect pregnancy test results?
An infection in the urinary tract will cause the appearance of blood in the urine sample, including red blood cells and whilte blood cells.
What makes antibodies in the body?
Yes, by certain white cells in the blood. Some of these cells produce free floating antibodies while others present their antibodies on their surface receptors. These different systems fight infection by different kinds of organisms.
What happens to antibodies numbers when fighting an infection?
They increase. A normal level is around 10 for a white blood cell count, but this can increase to hundreds in cases of severe infection.
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.
