• diagnosis
  • Because of its simplicity and safety to the laboratory worker, it has been recommended as a useful test for the serologic diagnosis of toxoplasmosis. (ajtmh.org)
  • Hemagglutination phenomenon is almost commonly used for diagnosis of infection produced by Orthomyxoviruses, paramyxoviruses, and the abroviruses-togaviruses (including rubella), flaviviruses, and bunyaviruses. (microbeonline.com)
  • A modified counterimmunoelectrophoresis and a conventional indirect hemagglutination test were compared for routine diagnosis of human hydatid disease in an endemic area in the Middle East. (ajtmh.org)
  • In particular, diagnosis of eperythrozoonosis is complicated by lack of readily identifiable parasitemia in latent and chronic infections, rapid loss of parasitemia at the time of onset of clinical signs in acutely ill pigs and the lack of sensitive and specific laboratory tests for the organism.

  • A puppy with minimal symptoms can recover in 2 or 3 days if the IV fluids are begun as soon as symptoms are noticed and the CPV test confirms the diagnosis. (wikipedia.org)
  • serum
  • The highest dilution of serum (Ab) that prevents hemagglutination is called the HAI titer of the serum. (microbeonline.com)
  • Prepare two-fold dilutions of patient/test serum to be tested e.g. from 1:4 to 1:1024. (microbeonline.com)
  • Reproducibility both between tests on a serum and between similar sera was significantly improved over typical results using antigens from whole parasite extracts. (ajtmh.org)
  • This means that the patient's serum gives a positive indirect Coombs test at any dilution down to 1/16 (1 part serum to 15 parts diluent). (wikipedia.org)
  • If a few weeks later the same patient had an indirect Coombs titer of 32 (1/32 dilution which is 1 part serum to 31 parts diluent), this would mean that she was making more anti-Rh antibody, since it took a greater dilution to abolish the positive test. (wikipedia.org)
  • diagnostic
  • Serologic tests have received a great deal of emphasis as diagnostic aids in suspected infections with Toxoplasma , the methylene-blue dye test being the most widely used. (ajtmh.org)
  • sera
  • These figures were confirmed by randomised FTA-ABS tests on 504 sera with repeat AMHA-TP tests. (bmj.com)
  • The test was performed with unconcentrated human sera and the lines stained in an aqueous solution of Ponceau red. (ajtmh.org)
  • Cross-reactivity with sera of patients with other parasitic infections was noted with indirect hemagglutination but not with counterimmunoelectrophoresis. (ajtmh.org)
  • There was no cross-reactivity with sera of patients with autoimmune disorders by either test. (ajtmh.org)
  • occur
  • These investigations showed that (1) non-specific positive gonococcal antibody test results occur rarely, (2) at least half the people who have had gonorrhoea remain seropositive (with titres of 1/40 to 1/160), and (3) a positive test result is more significant the younger the patient and the higher the titre. (bmj.com)
  • After the transfusion of incompatible blood, hemagglutination may occur in the bloodstream and cause severe (sometimes fatal) complications. (thefreedictionary.com)
  • infections
  • To evaluate the usefulness of the test result the following population groups were studied: 1376 patients undergoing medical examination for gonorrhoea (386 had gonorrhoea), 1384 healthy people aged 15-65, 54 patients with meningococcal disease, 30 children with respiratory tract infection, and 254 patients with evidence of various diseases other than neisserial infections that might be associated with symptoms of arthritis. (bmj.com)
  • disease
  • A CPV test should be given as early as possible if CPV is suspected in order to begin early treatment and increase survival rate if the disease is found. (wikipedia.org)
  • General biosecurity protocols including adequate quarantine, testing, and disinfection can help prevent the entry or spread of the disease into a herd. (wikipedia.org)
  • results
  • When isolated reactivity or non-reactivity in the AMHA-TP test was investigated an estimated margin of error of 0.7% probably wrongly non-reactive and 0.008% presumably false non-reactive results were found. (bmj.com)
  • However, the test is relatively cumbersome and time intensive (few days) relative to EIA kits that give quick results (usually several minutes to a few hours). (wikipedia.org)
