Interpretation of PSA Test Results Doctors 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. ...
RESULT INTERPRETATION (DO NOT ATTEMP TO INTERPRET RESULT AFTER 10 MINUTES) Positive (PSA level ≥ 4ng/ml): both test and control lines appear. Negative (PSA level < 4 ng/ml): only control line appears. Validity: control line should appear in every valid test. If the control line does ...
The complexity of PSA interpretation in clinical practice. Surgeon. 2014 Dec;12(6):323-327. 摘要 前列腺特异性抗原 ( PSA ) 是前列腺癌诊断的核心 . 实验室引用 PSA 的临界参考范围,但这些边界内的值 并不等同于没有癌症,高于阈值水平也不等同于存在 癌症.惯例规定,当根据 Hybritech 免疫测定技术校准 ...
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...
It was during this aspect of our validation study that we obtained a positive PSA result from semen-free vaginal samples and also with a commercially available contraceptive foam. The validation results and interpretation guidelines for when the kits are used at the Centre of Forensic Sciences are...
During the early diagnosis of CSPCa, the 68Ga-PSMA PET/CT SUVmax-based prediction model is a much better diagnostic method than PSA-based tests, as revealed by the larger AUC value and higher sensitivity and specificity of this test than those of PSA- and mpMRI-based tests. Figures 2 ...
Of 64 436 with a valid PSA test result, 6857 (11%) had a PSA level between 3 ng/mL and 19.9 ng/mL, of whom 5850 (85%) had a prostate biopsy. After a median follow-up of 10 years, 549 (0.30 per 1000 person-years) died of prostate cancer in the intervention group vs 647 ...

Linear regression models of mean PSA levels and fasting times revealed a statistically important relationship at certain fasting times.Applying a dynamic mathematical model to explore the clinical effect of fastingsuggests minimal impact on serum PSA result interpretation. Thus, patients can betested for...
