what the risks are blood test, brucella serology, brucella antibody test, titer, an analysis of blood to detect, antibodies against brucella, bacteria that causes, disease brucellosis, blood is drawn, a vein on the inside, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to apply pressure, restrict blood flow, the vein, veins below the band to fill, blood, a needle is inserted, vein, blood is collected in an air-tight vial, a syringe, band is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, an infant, young child, area is cleansed, antiseptic, punctured, a sharp needle, a lancet, blood collected, pipette, small glass tube, on a slide, onto a test strip, into a small container, cotton, a bandage applied, puncture site, any continued bleeding, blood is then analyzed, serology refers, study of serum, its antibody content, certain microorganisms stimulate the body to produce these antibodies, an active infection, antibodies react, antigens in specific ways, confirm the identity, the specific microorganism, several serology techniques, used depending on the suspected antibodies, serology techniques include agglutination, precipitation, complement-fixation, fluorescent antibodies, brucella, serum agglutination test, sat, the simplest, most widely used, , no special preparation, infants, children, test depends on child's age, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, the needle is inserted to draw blood, feel moderate pain, others feel only a prick, stinging sensation, some throbbing, this test performed, brucellosis is suspected, a normal results shows no antibodies to brucella, first few days to weeks of exposure to an antigen, slight antibody production, the disease progresses, antibodies, a disease is suspected, repeated 10 days to 2 weeks, first test, a rise in titer, antibody count, expected, titers of greater than 1, 80 suggest past infection, titers of 1, 160, higher, suggestive of current infection, cross-reaction to bacteria yersinia, francisella, vibrio, immunizations, make the test falsely positive, antibodies, detected, has likely been exposure, brucella bacteria, brucellosis, risks associated, having blood drawn, excessive bleeding, fainting, feeling light-headed, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, a serology test, a patient has ever been exposed to a particular antigen, does not necessarily indicate a current infection, increasing antibody levels, more likely to indicate a current infection, veins, arteries vary in size, obtaining a blood sample.
