BURLINGTON, N.C. -- August 14, 2013

Laboratory Corporation of America^® Holdings (LabCorp^®) (NYSE: LH) applauds
the recent recommendation of the National Kidney Foundation (NKF) that all
persons age 60 or older receive urine screening for chronic kidney disease
(CKD), defined as abnormalities of kidney structure or loss of kidney function
over time. This recommendation is an expansion of prior screening guidelines
that were based on the presence of diabetes, hypertension and other risk
factors not specifically based on age. The NKF’s announcement responds to a
study by a team of researchers from Johns Hopkins University published in the
most recent issue of the American Journal of Kidney Diseases, which found that
nearly six in ten Americans (59.1%) will develop at least moderate kidney
disease in their lifetimes, more than will develop heart disease, diabetes, or
invasive cancer. Pointing to the study, the NKF calls on physicians and
patients to practice primary prevention more aggressively, and specifically to
add urine albumin testing to annual physical examinations for high-risk groups
– those aged 60 or older and with high blood pressure or diabetes – to foster
earlier diagnosis of kidney damage. Because CKD is substantially
underdiagnosed today, it is associated with high morbidity and mortality and
is extremely costly.

The NKF estimates that 26 million Americans, most of them undiagnosed,
currently have CKD. In its earlier stages, CKD may have no symptoms and can
best be detected through routine laboratory testing. LabCorp offers testing to
detect the presence of albumin in the urine, which helps detect kidney damage
beyond that which tends to occur with normal aging, and a serum creatinine
test, from which the estimated glomerular filtration rate (eGFR), a measure of
kidney function, is calculated. As the disease progresses, complications,
including cardiovascular disease, anemia, dyslipidemia, bone disorders, and
other problems, frequently develop. Earlier diagnosis of moderate CKD can help
to delay or stop progression of CKD through lifestyle changes or medication
before those complications arise and can help prevent kidney failure requiring
dialysis or a kidney transplant.

LabCorp has developed innovative programs to assist clinicians and patients in
diagnosing and treating CKD and other chronic diseases. LabCorp provides
patient-specific results based on the leading international clinical practice
guidelines for CKD (Kidney Disease: Improving Global Outcomes, or KDIGO®).
LabCorp physicians can easily request that the CKD report be added to any of
their usual chemistry profiles (that include serum creatinine) by selecting
the additional option: LabCorp CKD Report (910343). These support tools now
accompany millions of test results from LabCorp.

Increased disease awareness, among both physicians and patients, is the first
step toward making an impact in CKD treatment. “These expanded screening
guidelines will assist in the detection of CKD in more individuals that are
currently undiagnosed and untreated, and should help more patients get
treatment before serious CKD complications arise,” said Dr.Mark Brecher,
LabCorp’s Chief Medical Officer. “The LabCorp CKD Program is another example
of LabCorp’s focus on providing physicians and their patients with clinically
significant data that will lead to earlier and better treatment and improved
health outcomes.”
