Ages 65 Years and Older: Laboratory and Other Tests


Bone mineral density screening (In the absence of new risk factors, screen no more frequently than every 2 years.)

Cervical cytology: Discontinue in women with evidence of adequate negative prior screening results (three consecutive negative cytology results or two consecutive negative co-test results within the previous 10 years, with the most recent test performed within the past 5 years) and no history of CIN 2 or higher.

Colorectal cancer screening: colonoscopy every 10 years (preferred)

Other methods include: 

  1. Fecal occult blood testing or fecal immunochemical test, annual patient-collected (each method requires two or three samples of stool collected by the patient at home and returned for analysis. A single stool sample obtained by digital rectal examination is not adequate for the detection of colorectal cancer.)
  2. Flexible sigmoidoscopy every 5 years
  3. Double contrast barium enema every 5 years
  4. Computed tomography colonography every 5 years
  5. Stool DNA

Diabetes testing (every 3 years)

Hepatitis C virus testing (one-time testing for persons born from 1945 through 1965 and unaware of their infection status)
Lipid profile assessment (every 5 years)
Mammography (yearly)
Thyroid-stimulating hormone testing (every 5 years)

High-Risk Groups (See High-Risk Table for more information.)

Hemoglobin level assessment
Human immunodeficiency virus (HIV) testing
Sexually transmitted infection testing
Thyroid-stimulating hormone testing
Tuberculosis skin testing
