New insights about personal genomes will give pathologists and clinical laboratory scientists different ways to use genetic tests in the screening, diagnosis, and treatment of disease
Here is a human genome curve ball for pathologists and clinical laboratory scientists engaged in genetic testing in their medical laboratories. New research indicates that a larger number of humans than was once believed may have more than one genome. This has implications for many medical and health issues.
Until recently, scientists assumed that, as a rule, each individual had a unique genome. Conditions such as mosaicism and chimerism were considered a rarity.

New lab test market could open up if research findings lead to a useful clinical laboratory test that predicts prostate cancer recurrence
Over the past decade, clinical laboratory tests that can predict the occurrence or recurrence of breast cancer have opened up a profitable market for the companies that developed these technologies. Now, new research may become the basis of a useful medical laboratory test that could be predictive of prostate cancer relapse.
Of course, pathologists know that several years of further development and regulatory approvals will be needed before this research produces a lab test for clinical use that can reliably predict the recurrence of prostate cancer. What makes this development exciting is that there is a huge and untapped demand to help men with prostate cancer and their physicians make informed decisions about treatment options and long-term prognosis.
