Labcorp's lab work untrustworthy
The primary task of LabCorp is to provide trustworthy numbers on which one can make medical decisions. I have had two results in the last two lab visits to Labcorp that had seriously erroneous numbers. In both cases I verified the correct numbers with lab tests at Quest Diagnostics which has never failed to give accurate info. The first was an A1C test, which LabCorp reported at 5.6. I am on an ultra-low carbohydrate diet, and so a 5.6 is an impossible number for me, and every other test in 3 years has been 5.1 or 5.2. The Quest test taken a few days later came back at 5.2. The second test a few months later was a lipids panel which LabCorp reported a triglycerides of 430. This also was a crazy number as mine had never been above 150. The Quest test taken a few days later showed a typical triglycerides number of 109. They must not be re-calibrating their lab equipment. If you can't get reliable numbers from a lab, then it's not wise to use them, and I will never be using them again.
