About the Tests

Every few years, the recommendations for routine screenings are revised based on the latest research.  Here is the background on some of the most common tests

Blood-pressure measurement

• Comments: Blood pressure is tested by constricting a cuff above the elbow, then listening with a stethoscope to the pulse as the cuff is released and the blood is allowed to flow through the arteries.

• Frequency: At least once every other year if you have normal blood pressure. If you have borderline high pressure, several tests over a couple of weeks or months are recommended.

Blood cholesterol

• Comments: A simple blood test measures levels of total, HDL (good) and LDL (bad) cholesterol.

• Frequency: Once every five years starting at age 20. If results are not within the normal range, more frequent tests will be recommended.

Fecal-occult blood

• Comments: A stool sample is smeared on a test card. The test detects blood in the stool, which can indicate colon or rectal cancer.

• Frequency: Every year starting at age 50

Sigmoidoscopy

Comments: A flexible viewing scope is inserted in the colon, allowing the doctor to visually examine the colon for cancer and other abnormalities.

Frequency: Every three to five years starting at age 50.

 

Chest CAT scan

• Comments: This imaging test screens for lung cancer.

• Frequency: Smokers and former heavy smokers should have the test every year starting at age 50.

Test: Fasting glucose test

• Comments: A simple blood test screens for diabetes.

• Frequency: Every three years starting at age 45.
