• antigens
  • The present authors' objective was to assess their diagnostic value by developing scores from a panel of specific antigens tested by two techniques (electrosyneresis and double diffusion) to discriminate active HP from other interstitial lung diseases. (ersjournals.com)
  • These limitations may be due to the use of poorly purified antigens, the lack of the specific inciting antigen in the test panel, inappropriate techniques 8 or, in epidemiological studies, the use of inappropriate control groups 5 , 9 , 10 . (ersjournals.com)
  • Subjects were tested by two serological techniques (electrosyneresis and double diffusion) for a panel of seven antigens. (ersjournals.com)
  • Aspergillus
  • Chest X-rays and CT scans, raised blood levels of IgE and eosinophils, immunological tests for Aspergillus together with sputum staining and sputum cultures can be useful. (wikipedia.org)
  • Symptoms lasting more than 3 months, usually including weight loss, fatigue, cough, coughing blood (haemoptysis) and breathlessness A blood test or tissue fluid test positive for Aspergillus species Aspergilloma An aspergilloma is a fungal mass caused by a fungal infection with Aspergillus species that grows in either scarred lungs or in a pre-existing lung cavity, which may have been caused by a previous infection.

  • sera
  • w^ The following general remarks on the precipitin sera are quoted from the annual report of the Imperial Serologist for 1937-38 : "(i) Some antisera produced against known sera are sometimes found unsuitable for the test. (archive.org)
  • His experiments with the sera consisted in the precipitin tests. (ajtmh.org)
  • Nineteen strains of VEE virus, identical by neutralization (N) tests, were shown by hemagglutination-inhibition tests with anti-E 2 glycoprotein sera to represent a new subtype VI of the VEE complex. (ajtmh.org)
  • indicates
  • tjie pecipitin test indicates the presence of the blood protein of an aSmi ^ a known species its utility has been extended to protein materials other than blood stains The origin of skin, flesh, bone or even secretions such as saliva, milk and semen, is established by this test. (archive.org)
  • The presence of precipitin lines indicates that the strain produced toxin that reacted with the antitoxin. (wikipedia.org)
  • known
  • Strains to be tested, known positive and negative toxigenic strains are streaked on the agar's surface in a line across the plate, and at a right angle to the antitoxin paper strip. (wikipedia.org)
  • The antigen is quantitated by measuring the diameter of the precipitin circle and comparing it with the diameters of precipitin circles formed by known quantities or concentrations of the antigen. (wikipedia.org)
  • method
  • Therefore, a graph that compares the quantities or concentrations of antigen in the original samples with the areas or the squares of the diameters of the precipitin circles on linear scales will usually be a straight line when all circles have reached their end points (equivalence method). (wikipedia.org)
  • lines
  • After 24 hours of incubation at 37 degrees Celsius, plates are examined with transmitted light for the presence of fine precipitin lines at a 45-degree angle to the streaks. (wikipedia.org)
  • negative
  • The test, as expected, is frequently negative in acute amebic dysentery and, desirably, it is often negative in the asymptomatic carrier state, permitting an exclusion of up to 50 per cent of individuals who harbor this parasite without symptoms. (ajtmh.org)
  • determine
  • citation needed] Methods from around the world involved saliva and examination of the mouth and tongue to determine innocence or guilt, as a precursor to the Polygraph test. (wikipedia.org)
  • further
  • The results so obtained is confirmed by testing further dilutions of the extract. (archive.org)
  • The test was further refined for forensic use by the Swiss chemist Maurice Müller in the 1960s. (wikipedia.org)
