Which diseases can the blood test predict? For these 67 diseases, the median detection rate using the protein signature was 45.5% compared with 25% when just the clinical model was used, with a 10 ...
The Prostate Health Index (PHI) is a PSA-based blood test for early prostate cancer screening. It may be used to determine when a biopsy is needed. [32] [46] Prostate cancer antigen 3 is a urine test that detects the overexpression of the PCA3 gene, an indicator of prostate cancer. [32] [46] [47] [44]
PCA3 has been shown to be useful to predict the presence of malignancy in men undergoing repeat prostate biopsy. [9] [10] This means that it could be useful clinically for a patient for whom digital rectal examination and PSA suggest possible prostate cancer, but the first prostate biopsy returns a normal result. This occurs in approximately 60 ...
It appears to provide more accuracy in identifying early prostate cancer than the standard prostate cancer marker, PSA. "EPCA-2" is not the name of a gene. EPCA-2 gets its name because it is the second prostate cancer marker identified by the research team. This earlier marker was previously known as "EPCA", [1] [2] but is now called "EPCA-1".
The Food and Drug Administration (FDA) has recently approved a blood test screening for colorectal cancer that has an over 83% success rate at detecting the presence of this form of cancer.
To develop the test, researchers sequenced nearly 60,000 genes, eventually identifying 54 markers of prostate cancer. They found 17 of these markers were further stratified to indicate high-grade ...
