Interpretation of PSA Test ResultsDoctors check ‘free PSA’ if a man has slightly raised level of ‘total PSA’. The ratio of free to total PSA helps decide whether the person is at an increased risk of having prostate cancer and whether a biopsy is essential....

as it has been reported for total and free prostate specific antigen (tPSA, fPSA) measurements, the surveillance of the analytical performances in standard quality control programs is not enough and further steps should be moved to pursue the appropriate interpretation of the test results [3, 4]...

This slows the flow of reagents and lead to high background, making the interpretation of results difficult. 2. Optimal assay performance requires strict adherence to the assay procedure described in this insert. Deviations may lead to aberrant results. 3 As with any tests, the Test should not...

INTERPRETATION OF RESULTS Negative: Only one colored band appears on the control (C) region. No apparent band on the test (T) region. Positive: in addition to a pink colored control (C) band, a distinct pink colored band will also appear in the test (T) region. Invalid: A total absen...
As clear guidelines for the use of the two tests continue to emerge, clinical laboratory professionals will increasingly be involved in providing interpretation of results for these tests. 展开 年份: 2022 收藏 引用 批量引用 报错 分享 全部来源 免费下载 求助全文 ResearchGate ResearchGate (全网免费下载...
Reports on the debate concerning the interpretation and use of the percent free prostate specific antigen (PSA) test results in the United States. Two approaches on the use of the assay presented during the 1996 American Urological Association's meeting; Proposed cutoff percentages; Relative risk ta...
PSA test results in a highly negative biopsy rate, but the combination of 68Ga-PSMA PET/CT and PSA tests provides a good performance-efficiency-diagnostic model to improve the net benefit and reduce the number of unnecessary prostate biopsies. PSA alone in the gray zone is not appropriate for...
