FAQ for Doctor

The PURE Index Test is a simple non-invasive urine test that provides an assessment of a patient’s risk for prostate cancer. It combines two biomarkers along with patient PSA level and age in a complex algorithm that generates a Index for the risk of having prostate cancer diagnosed by prostate biopsy. The PURE Index Test recommends patients and doctors to make better-informed decisions in determining if a prostate biopsy is needed.

The PURE Index Test is a follow-up urine test after an abnormal PSA (PSA level >4ng/mL). It is a simple, non-invasive test with high accuracy of PCa risk evaluation. By specifically assessing the risk for prostate cancer after an abnormal screening result, the PURE Index Test could help 66% low-risk men to avoid having a prostate biopsy, while distinguishing men with an elevated risk who may benefit from early intervention.

PURE Index Test measures the polyamine levels in urine. Levels of these biomarkers are combined with the patient’s clinical information and PSA level. Then, it is processed using a sophisticated algorithm to calculate a patient’s individualized risk of finding prostate cancer if a prostate biopsy were to be performed.

The PURE Index Test is applicable to patients with elevated PSA levels, with or without prior prostate biopsy.

The PURE Index Test can be used in the initial and subsequent management of patients with elevated PSA level. The test can overcome the diagnostic pitfall, the low diagnostic accuracy, of the PSA test and the prostate biopsy. For patients with the low PURE Index or prostate biopsy does not show any evidence of cancer, one can perform the PURE Index test annually for monitoring purpose.

The PURE Index Test does not provide a diagnosis of prostate cancer. Instead, it is an evaluation of a patient’s risk for prostate cancer. The PURE Index is designed to help evaluate the necessity of performing a prostate biopsy.

The PURE Index Test provides an assessment of a patient’s risk for prostate cancer if a prostate biopsy were performed. Patients with an elevated PURE Index result should be considered for further evaluation and treatment. The PURE Index Test result should be interpreted in conjunction with other patient-specific information to develop a personal patient management plan.

PURE Index Test is not indicated in men with:
  • Patient with recent urinary tract infection within 6 weeks prior to urine collection.
  • Patient with recent urethral instrumentation, such as Foley catheter insertion, cystoscopy etc., within 6 weeks prior to urine collection.
  • Patient with digital rectal examination done within 7 days prior to urine collection.
  • Patient with consumption of 5 alpha reductase inhibitors in the past 6 months.
  • Patient with previous history of other malignant neoplasms

The PURE Index Test result is usually provided within 7 working days of receiving a completed requisition and patient sample.

The PURE Index Test result can be received in the manner most compatible with the doctor’s needs. Results can be reported through courier delivery. There is also an easy-to-understand patient report that doctors can use to explain PURE Index Test results.

The PURE Index Test is performed by the medical laboratory operated by Hong Kong Baptist University, which is collaborated with the New Life Medicine Technology Company Limited on the PURE Index Test. The whole sample handling, testing and report issuing process are under the supervision of a recognized medical laboratory technologist with a well-established quality assurance system.
