PCA3 Detection Service

Prostate cancer antigen 3 (PCA3) is a biomarker commonly used in prostate cancer research. Creative BioMart Biomarker provides customers with quantitative RT-PCR testing services to help customers study PCA3 mRNA levels. This test is only suitable for research use, not for personal medical and diagnostic use.

HE4 Testing

Biomarker Application Area: prostate cancer
* Perform three replicate tests on each sample, and include appropriate controls in each assay.

Assay Background

PCA3 is a gene expressed only in prostate tissue, also known as differential display clone 3 (DD3), which is highly overexpressed in prostate cancer. Because prostate-specific antigen (PSA) not only has elevated serum expression levels in prostate cancer, it also has abnormal expression in non-cancerous pathological conditions such as prostate inflammation and benign prostatic hyperplasia. Therefore, the specificity for prostate cancer is poor, and some other more specific and sensitive biomarkers need to be selected in combination with it. Compared with PSA, PCA3 has higher specificity and is a potential biomarker for the diagnosis of prostate cancer. The PCA3 test has been approved by the FDA to assess the risk of prostate cancer before prostate biopsy. PCA3 is expressed as a long non-coding RNA, which is overexpressed in urine after DRE (digital rectal examination). Therefore, PCA3 mRNA levels in urine samples are generally analyzed. The analysis of PCA3 can help predict the results of prostate biopsy, and the combination of PCA3 and PSA can improve the diagnostic sensitivity and specificity of PSA.
