  • For all tests, the relationship of predicted to observed risk in different populations and their incremental contribution over conventional predictors, optimal implementation, and relevance to patients receiving current therapies need further study. (
  • Maintains ethical standards in the performance of testing and in interactions with patients, co-workers and other health care professionals. (
  • Studies have shown that because the PCA3 gene is highly specific for prostate cancer, the Progensa PCA3 score predicts the results of repeat biopsies more accurately than traditional serum PSA testing in patients who have had one or more previous negative prostate biopsies. (
  • Diego Cardeñosa, Jessica Quinlan, Kwok Ho Shea and Demian Chapman investigated a real-time PCR method that can detect nine of the 12 CITES-listed shark species. (
  • Real-time PCR methods reduce the number of steps required to identify species from their products, and improves on DNA barcoding because they don't need to run in a laboratory. (
  • If M. tuberculosis complex is isolated from a new patient, drug susceptibility testing will be performed using culture or molecular methods. (
  • however, with the completion of the system, molecular diagnostics utilization will greatly increase as order-to-report on the same day allows hospitals to conduct molecular diagnosis and this will lead to a breakthrough in achieving on-time customized patient care. (
