  • Hepatitis A Vir
  • Twenty-three symptomatic persons were tested by differential radioimmunoassay for immunoglobulin M (IgM) (acute-phase) hepatitis A antibody (anti-HAV) and all 23 were documented to be infected with hepatitis A virus (HAV). (mysciencework.com)
  • sensitivity
  • Performance of medical tests is often described in terms of: sensitivity: The percentage of the results that will be positive when HIV is present specificity: The percentage of the results that will be negative when HIV is not present. (wikipedia.org)
  • Tests selected to screen donor blood and tissue must provide a high degree of confidence that HIV will be detected if present (that is, a high sensitivity is required). (wikipedia.org)
  • Wassermann
  • In previous communications, 1 our efforts were directed toward a comparison of the Kolmer Wassermann test and the Kahn precipitation test against known clinical data, irrespective of treatment, and our percentage of agreements was low in comparison with that of other investigators. (jamanetwork.com)
  • Our present study is confined to a known group of syphilitic patients compared both before treatment and throughout treatment to the persistently negative serologic phase, or in a small group to serologic relapse or Wassermann-fastness. (jamanetwork.com)
  • The material for this study comprised one hundred and five syphilitic dispensary patients, eighty-three with early and twenty-two with latent infections, on whom 910 serologic examinations were made, including both the Kolmer Wassermann and the Kahn precipitation tests on identical serums. (jamanetwork.com)
  • laboratory
  • The DoDSR traces its origins to 1985 and the beginnings of the United States Armed Forces HIV screening program (originally referred to as the HTLV-III screening program), when serum remaining after periodic laboratory testing of service members was retained first by the Walter Reed Army Institute of Research (WRAIR), then later systematically archived in the Army/Navy Serum Repository, the precursor to the DoDSR. (wikipedia.org)
  • Early laboratory testing was performed via contracted private laboratories. (wikipedia.org)
  • A condition of some early laboratory testing contracts specified that remnant serum were to remain in frozen storage. (wikipedia.org)
  • diagnostic tests
  • All diagnostic tests have limitations, and sometimes their use may produce erroneous or questionable results. (wikipedia.org)
  • These diagnostic tests are combined with careful donor selection. (wikipedia.org)
  • Some keystones were to recognize its importance for blood transfusion (including reliable diagnostic tests), hemolytic disease of the newborn (including exchange transfusion), and very importantly the prevention of it by screening and prophylaxis. (wikipedia.org)
  • By virtue of its long history and of its simplicity, it has been one of the most widely employed tests for rickettsia on a global scale, despite being superseded in many settings by more sensitive and specific diagnostic tests. (wikipedia.org)
  • serum
  • HIV tests are used to detect the presence of the human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS), in serum, saliva, or urine. (wikipedia.org)
  • Dilution of patient's serum are tested against suspensions of the different Proteus strains. (wikipedia.org)
  • ELISA
  • Other testing modalities currently under evaluation are also discussed, including IgG vlse C6 peptide ELISA, other two-tiered testing strategies, rapid diagnostics, and PCR. (docplayer.net)
  • positive
  • Elevated liver function tests are expected with positive tests for anti-HCV by a variety of methods. (neurologyadvisor.com)
  • False positive: The test incorrectly indicates that HIV is present in a non-infected person. (wikipedia.org)
  • This allows for monitoring of infected individuals easily, compared to anonymous testing that has a number attached to the positive test results. (wikipedia.org)
  • In nonhuman animals, Babesia canis rossi, Babesia bigemina, and Babesia bovis cause particularly severe forms of the disease, including a severe haemolytic anaemia, with positive erythrocyte-in-saline-agglutination test indicating an immune-mediated component to the haemolysis. (wikipedia.org)
  • methods
  • As a result, it has largely been supplanted by other methods of serology, including indirect immunofluorescence antibody (IFA) testing, which is the gold standard. (wikipedia.org)
  • nucleic
  • A combination of antibody, antigen and nucleic acid tests are used by blood banks in Western countries. (wikipedia.org)
  • citation needed] In the US, the Food and Drug Administration requires that all donated blood be screened for several infectious diseases, including HIV-1 and HIV-2, using a combination of antibody testing (EIA) and more expeditious nucleic acid testing (NAT). (wikipedia.org)
  • disease
  • Blood tests are often negative in the early stages of the disease. (wikipedia.org)
  • A reported increase in human babesiosis diagnoses in the 2000s is thought to be caused by more widespread testing and higher numbers of people with immunodeficiencies coming in contact with ticks, the disease vector. (wikipedia.org)
  • Samples
  • We identified 43 samples with serologic RhCE variants. (nih.gov)
  • The index case was not icteric and only moderately symptomatic and was diagnosed retrospectively to have viral hepatitis, type A by serologic determination of IgM anti-HAV in blood samples. (mysciencework.com)
  • negative
  • False negative: The test incorrectly indicates that HIV is absent in an infected person. (wikipedia.org)
  • The DoDSR, along with its precursor repositories, were designated as the ultimate storage facility for all serologically negative HIV specimens obtained through military HIV testing programs. (wikipedia.org)
  • small
  • Although a small number of specimens were collected directly for health surveillance outside of existing HIV testing channels, specimens collected in this manner suffered from lack of standardization. (wikipedia.org)
  • Several
  • For example, a stock that has declined to $20 on several occasions without moving lower may be expected to test this support level once again. (thefreedictionary.com)
  • population
  • Note some population test DR3 or DQA1:DQB1, the DR3-DQ2 serotype is generally synonymous in frequency with DQ2.DR3-DQ2 probably originated from Central or West Africa. (wikipedia.org)
