title: [Study of auxiliary diagnostic value of viral load test for samples with indeterminate HIV antibody detection results].
abstract: OBJECTIVE
  To evaluate the auxiliary diagnostic value of viral load test for samples with indeterminate HIV antibody detection results.
  
  
  METHODS
  Thirty-two samples with indeterminate HIV antibody detection results collected from MSM were used for two viral load tests in Tianjin in 2015. Follow up was conducted for this population to confirm their HIV infection status.
  
  
  RESULTS
  Virus loads were detected in the 2 viral load tests. In the follow-up survey, the results of HIV antibody test of all the samples were positive. The results of viral load test were completely consistent with those of HIIV antibody confirmation test.
  
  
  CONCLUSIONS
  The viral load test was effective in the auxiliary diagnosis of HIV infection in window phase, which can be used for the samples with indeterminate HIV antibody detection results.
