Quest Diagnostics Inc. (NYSE:DGX) and Laboratory Corp. of America (NYSE:LH) are noteworthy today for staying positive in a sea of red.

Consumer discretionary stocks, in particular, are lower today as crude oil approaches $100 a barrel, with traders expecting consumer sales to take a hit as rising gasoline prices take a larger bite of available cash. Healthcare stocks tend to hold up better, with patients and physicians more reluctant to delay medical procedures even when money is tight.

Lab Corp shares currently are up 1.39 percent to $88.86. Quest is also bucking the trend, rising 37 cents to $56.55, just under a percent in mid-afternoon trading.
