The Value of Clinical Laboratory Services
Value Now…
Clinical laboratory testing plays an essential part in the delivery
of quality health care. Laboratory tests provide physicians with
objective data needed to promptly diagnose and effectively treat
and monitor disease. It is estimated that lab testing has an impact
on over 70 percent of medical decisions, yet laboratory services
account for only three percent of health care spending (and two
percent of Medicare expenditures). By equipping physicians with
critical information, laboratory tests ultimately save lives and
reduce overall health care costs.
…And In The Future
As the baby-boom generation reaches retirement, the number of
Americans over age 65 will increase fivefold. This demographic
shift will focus more attention on preventable diseases associated
with an aging population, including cancer, stroke, diabetes,
hypertension and cardiovascular disease. The recently enacted
Medicare Prescription Drug, Improvement and Modernization Act
(P.L. 108-173) added coverage for diabetes and cardiovascular
disease screening tests, as well as an initial physical for all
Medicare beneficiaries. Clinical laboratory services will play
a vital role in these screening and prevention efforts, which
will result in health benefits for Medicare beneficiaries and
a healthier financial outlook for the Medicare program.
How Lab Testing Works
Clinical laboratory tests are furnished in three distinct settings:
independent laboratories, hospital laboratories, and physician
office laboratories. The American Clinical Laboratory Association's
(ACLA's) membership consists of local, regional and national
independent clinical laboratories. Independent laboratories are
laboratories that are not located in a hospital or physician office,
and which provide testing and related services to the medical
community. With their focus exclusively on clinical testing, independent
laboratories are able to offer a broad range of high quality services
cost-effectively.
A physician usually orders lab tests for one of three purposes:
diagnosis, screening or monitoring of a patient's disease
or condition. Once the physician determines that tests are needed
for an evaluation, the physician or another provider collects
a specimen from the patient and often sends it to the laboratory.
Less frequently, patients may go to a laboratory "draw station"
to have the specimen collected. When the laboratory receives the
patient's specimen, it is uniquely identified and examined
to make certain that it is appropriate for the ordered testing.
While some tests are manually evaluated, most tests are performed
using technically advanced instrumentation. For all testing, laboratories
employ teams of licensed, highly skilled medical professionals
specially trained to perform the analyses. After testing is completed,
the laboratory issues a report to the ordering physician.
How Labs Are Regulated
Clinical labs are regulated by the Clinical Laboratory Improvement
Amendments (CLIA), enacted in 1988. CLIA established stringent
federal quality standards for all clinical laboratories. ACLA
was an early and vigorous proponent of CLIA and continues to support
its implementation.
