Cholesterol is different from most tests in that it is not used to diagnose or monitor a disease, but to estimate the risk of developing a disease—specifically heart disease. Because high blood cholesterol has been associated with hardening of the arteries, heart disease, and a raised risk of death from heart attacks, cholesterol testing is considered a routine part of preventive health care.

Cholesterol testing is recommended as a screening test for all adults at least once every five years. It is usually ordered as part of a routine physical exam. It may be ordered alone or in combination with other tests including HDL, LDL, and triglycerides—often called a lipid profile.

Cholesterol is tested at more frequent intervals—often several times per year—in patients who have been prescribed a specific diet and/or drugs to lower their cholesterol. The test is used to track how well these measures are succeeding in lowering cholesterol to desired levels—and, in turn, of lowering the risk of developing heart disease.


Blood tests for triglycerides are usually part of a lipid profile used to identify the risk of heart disease. It is especially important for diabetics to have triglycerides measured as part of any lipid testing since triglycerides increase significantly when blood sugar is out of control.

Lipid profiles, including triglycerides, are recommended as routine tests to evaluate the risk of heart disease in healthy adults. The test for triglycerides is not often ordered alone since the risk of heart disease is based on cholesterol levels, not triglycerides. However, if you have been found to have high triglycerides and are being treated for it, a triglyceride test may be ordered to see if the treatment is working.

High-Density Lipoprotein (HDL)

The test of HDL cholesterol is used to determine a patient’s risk of heart disease. If a high cholesterol level is due to high HDL, a person is probably at low risk and further testing or treatment for high cholesterol is not advised. HDL is usually ordered with other tests, either with cholesterol or as part of a lipid profile, including LDL and triglycerides. The combination of total cholesterol and HDL is very useful for screening for heart disease since it is not necessary to fast for these two tests. A more complete lipid profile requires fasting for at least 12 hours prior to the test.

Prostate-Specific Antigen (PSA)

The PSA blood screen is used as a prostate cancer indicator. Measuring the ratio of free-PSA to total PSA in the patient’s blood provides additional information that helps your doctor distinguish prostate cancer from benign prostatic hypertrophy (BPH) and other non-cancer-related causes of high PSA. This ratio may also help predict whether prostate cancer is an aggressive, fast-growing disease or a slow-growing, non-aggressive form of the disease. The American Cancer Society recommends annual PSA and digital rectal exams for all men beginning at the age of 50. Men who have an increased risk for prostate cancer—such as American men of African descent and men with a family history of the disease—should start getting tested earlier, usually at age 40 or 45.

Thyroid Stimulating Hormone (TSH)

TSH testing may be used for the following reasons:


This test is performed on a fresh urine specimen. It is best if the specimen is collected in the lab in order to ensure proper container and collection protocol. Some of the urine constituents checked include pH, glucose, bilirubin, and the presence of white blood cells or red blood cells. A physician or other healthcare practitioner will be called to evaluate the results of urinalysis in order to determine whether or not further testing is needed.


Glucose testing is most commonly used to diagnose and manage diabetes. Since glucose levels in the blood vary with eating patterns, the most useful testing for diabetes is possible when the patient has fasted for eight hours before the test. Glucose testing can be used to screen healthy individuals for diabetes because diabetes is a common disease that begins with a few symptoms. Screening is especially important for people who are at a high risk of developing diabetes, including those with a family history of diabetes, those who are overweight, and those who are more than 40 years old.

Glucose testing is also ordered in patients who complain of symptoms that suggest diabetes, such as excessive thirst, weight loss, and frequent urination. By the time that these symptoms appear, a person may have already had diabetes for several years. Glucose testing is also performed during pregnancy because during this time some women develop a temporary type of diabetes called gestational diabetes.
