Preferred drug testing lab services?
“Keystone Laboratories, a sister company of Wolfe Drug Testing, is a forensic drug testing laboratory based out of Asheville, North Carolina. The lab maintains College of American Pathologists (CAP) certification and processes non-DOT urine and saliva drug test results. We have developed a specialized chain of custody form that accommodates urine and saliva samples which need traditional testing or confirmation services for instant kits. At Keystone, each specimen is checked for appropriate pH, specific gravity, and creatinine levels to further ensure the sample has not been diluted or adulterated. Detection of hydromorphone and hydrocodone is included in opiate screening protocols. Customized testing panels are also available to detect commonly abused substances, such as ecstasy and oxycodone, that are not picked up by standard screening protocols.
