In the United States, approximately
20% of adults have elevated cholesterol
levels.1 That means, 1 in every 5 American
adults has a cholesterol level of
240 mg/dL or greater.2
Various risk factors may contribute to
increase the incidence of elevated cholesterol
levels. Examples of these risk
factors include:
- Age and gender
- Familial history of early cardiovascular
disease
- History of diabetes
- History of hypertension
- Diet (high in saturated fats and
cholesterol)
- Being overweight
- Sedentary lifestyle
- Smoking

Cholesterol Tests
As the number of individuals with
hypercholesterolemia increases, the
use of home cholesterol tests is also
on the rise. These testing kits assist
many individuals in monitoring cholesterol
levels as a means of reducing
their risk of developing cardiovascular
problems. Pharmacists are
in a key position to make patients,
especially those with cardiovascular
risk factors, aware of the
options available for monitoring
cholesterol levels at home. While
the majority of at-home cholesterol
tests measure only total cholesterol
(Table 1), a few tests also can measure
low-density lipoprotein cholesterol
(Table 2), high-density lipoprotein cholesterol
(HDL-C) (Table 3), and triglycerides
(Table 4).
Patient Counseling
It is important for pharmacists to
thoroughly counsel patients about the
proper use of these tests. Prior to recommending
any of these tests, pharmacists
should always determine if the
patient has any coagulation disorders or
is taking anticoagulants, since the finger
stick could put such a patient at risk for
excessive bleeding. Therefore, the use of
at-home cholesterol tests is not recommended
for these patient populations.
They should be encouraged to seek the
advice of their primary health care
provider. Patients also should be advised
of certain factors that may interfere with
the results of these tests. Examples
include avoiding doses of 500 mg or
more of vitamin C, as well as avoiding
acetaminophen or naproxen within 4
hours of testing, since these factors may
interfere with results.1 Individuals also
should be encouraged to have follow-up
testing with a physician if they have any
further concerns, especially if their total
cholesterol is 200 mg/dL or greater, their
HDL-C is 40 mg/dL or less, or their
triglycerides are 150 mg/dL or greater.1
Encouraging patients to be knowledgeable
about their cardiovascular
risks, as well as informing them of measures
that can decrease their risks, are
other ways pharmacists can be indispensable
in promoting good health. The use
of at-home cholesterol monitors (examples
listed in Table 5) empowers patients
with an easy tool that can be used to routinely
monitor cholesterol levels. It is
important that pharmacists remind
patients to always follow up with their
physician for more thorough testing.
