Interpretive

Reference Range:

PCA3 Ratio

Interpretation

0-17

Negative – Result associated with decreased likelihood of a positive biopsy for prostate cancer.

18-24

Negative – Result should be interpreted with caution. Due to normal test variability, specimens with PCA3 scores near the cut-off may yield a different overall interpretation upon repeat testing.

25-31

Positive – Result should be interpreted with caution. Due to normal test variability, specimens with PCA3 scores near the cut-off may yield a different overall interpretation upon repeat testing.

>31

Positive – Result associated with increased probability of a positive biopsy for prostate cancer.

 

The Progensa PCA3 assay is an in vitro nucleic acid amplification test utilizing target capture, transcription-mediated amplification, and a hybridization-protection assay for amplicon detection, PCA3 Score is calculated as the ratio of PCA3 RNA copies to PSA RNA copies, multiplied by 1000.
