New Discovery by Massachusetts General Hospital May Help Medical Laboratories Preserve Blood for DNA Analysis, Thus Allowing Isolation of CTCs up to 72 Hours after Collection

Using GPIIb/IIIa inhibition, and ion chelation, researchers have developed a “universal” method for preserving blood up to 72 hours while keeping it viable for advanced rare-cell applications Through microfluidics and automation, clinical laboratories and anatomic pathologists have been able to detect ever-smaller quantities of biomarkers and other indicators of chronic disease. However, preserving sample quality is an essential part of analytical accuracy. This is particularly true in...

Health Insurers Balk at Paying for Multigene Panels While Clinical Pathology Laboratories and Physicians Pursue Evidence of Clinical Utility
