It is important to understand that a Pap smear may be referred to as "abnormal," but may not mean that a person has cervical cancer. Some organizations also recommend HPV human papilloma virus screening in certain populations during the Pap smear. This blood test measures the prostate specific antigen PSA levels in the blood.
Antigens are any substances that evoke responses from a person's immune system. That means preventive screenings, but also immunizations.

The retina is the tissue lining the back of the eye and is sensitive to light. These problems can be found during the seemingly simple tests performed during the eye exam. Slit lamp tests, the test where you rest your chin on the machine while the doctor shines light and moves a mirror back and forth to examine your eye, detects a wide range of conditions that can be evaluated including cataracts, corneal ulcers, and macular degeneration.
