Blood tests known as serologic tests scan your body for antibodies. They could entail a variety of laboratory procedures. For the diagnosis of various illness problems, various serologic test types are used. Serologic tests all share a similar trait. They are all concentrated on immune system proteins. This essential bodily function keeps you healthy by eliminating outside invaders that could harm you. Regardless of the technique the laboratory employs during serologic testing, the procedure for getting the test is the same. To comprehend serologic tests and their value, it helps to have a basic understanding of the immune system and the causes of illness.
Antigens are chemicals that cause the immune system to react. Normally, they are too small to be seen with the naked eye. They may enter the body of a person through the mouth, nasal passages, or a break in the skin. People are frequently affected by the following allergens: bacteria, fungi, viruses, parasites. Antibodies are created by the immune system to protect against antigens. These antibodies are little particles that bind to antigens and render them inactive.
The types of antibodies vary. As a result, there are numerous methods for identifying the presence of particular antibodies. These consist of: An agglutination assay determines whether antibodies will cause particle clumping when exposed to specific antigens, by checking for the presence of antibodies in bodily fluids, a precipitation test can determine whether two antigens are identical, by observing how these antibodies respond to target antigens, the Western blot test can detect the presence of antimicrobial antibodies in your blood.
The presence of antibodies in a blood sample frequently indicates that your immune system has responded to an antigen as a result of recent or previous exposure to a disease or an alien protein. By determining the presence of antibodies to common or non-foreign proteins or antigens in the blood, testing may also assist your doctor in making a diagnosis of an autoimmune condition. You may be immune to one or more antigens if specific types of antibodies are present. This implies that exposure to the antigen or antigens in the future won't cause sickness. Numerous disorders, such as brucellosis, which is caused by bacteria, amebiasis, which is caused by a parasite, measles, which is caused by a virus, rubella, which is caused by a virus, HIV, syphilis, and fungal infections can all be diagnosed using serologic testing.
After serologic testing, many types of care and therapy may be given. Often, it is based on whether antibodies were discovered. It can also depend on the type and strength of your immunological reaction. Your body may benefit from taking an antibiotic or another kind of medication to combat the infection. Your body's parasites, fungi, viruses, and bacteria will grow over time. Your immune system will create more antibodies in reaction. As the infection worsens, this makes the antibodies more visible.
