Disease/Disability Specific Screening/Diagnosis
Programs that offer any of a variety of tests which are used to identify people who have some form of cancer which, if caught in an early stage, may be treated with a higher probability of success.
Programs that conduct a series of tests which measure an individual's visual acuity, identify refractive errors that cause poor vision and check for eye diseases such as glaucoma; and prescribe corrective lenses in situations where there are vision problems. Eye examinations are offered by optometrists and ophthalmologists and are usually available through mobile eye clinics.
Programs that determine the proper amplification equipment for individuals who have hearing impairments and/or which evaluate the adequacy of present equipment.
Programs that offer hearing threshold tests for the purpose of identifying individuals whose ability to perceive sound falls outside the normal range. People who fail the screening test need an in-depth evaluation by an audiologist.
Programs that administer tests which identify individuals who have been exposed to hepatitis A, B or C by detecting the presence of associated antigens, antibodies or genetic material (DNA). Hepatitis is an inflammation of the liver caused by a variety of agents including viral infection (hepatitis A virus, hepatitis B virus, hepatitis C virus and delta agents), bacterial invasion and physical and chemical agents. Hepatitis A and delta agent hepatitis are spread primarily from person to person via the fecal-oral route, but may occur by contact with water or food contaminated by the virus. Hepatitis B and C are spread by blood and serum-derived fluids and by direct contact with body fluids. Depending on the type of hepatitis involved, screening may be particularly recommended for persons who have traveled or worked in countries with high rates of infection, sexually active homosexual men, injecting and non-injecting illegal drug users, persons who work with infected primates in a laboratory setting, persons with chronic liver disease, persons with clotting disorders, blood bank and dialysis workers, dental hygienists, and other members of health care teams who come into contact with blood, body fluids or body tissue.
Programs that offer HIV tests which are used to identify individuals who have been infected with the Human Immunodeficiency Virus (HIV) and are at risk for developing AIDS (acquired immune deficiency syndrome) or which are used to measure progression of the disease in people known to be infected. The most common HIV screening test is the enzyme immunoassay (EIA) which most frequently uses peripheral blood drawn from the arm or a finger as a sample, but can also be conducted using serum, oral fluids or urine. Repeatedly reactive EIA tests are confirmed using the Western blot or the immunofluorescence assay (IFA). The most common test that is used to measure disease progression is the PCR (polymeraise chain reaction) or viral load test. Many programs that provide HIV testing also provide pre-testing and post-test counseling which includes information about AIDS/HIV, reducing risks for HIV transmission, emotional support to help the individual deal with the testing process and test results, and information about and referral to other AIDS-related services.
Programs that take blood samples from young children to identify individuals who have ingested paint or other materials containing lead and have absorbed an undue amount of the substance. Results may lead to continued surveillance, testing, referrals for medical evaluation, and/or housing inspection to identify lead hazards and prevent further occurrences of lead poisoning. Included are screenings conducted during home visits and clinic-based screening.
Sexually Transmitted Disease Screening
Programs that identify individuals who have contracted gonorrhea, syphilis, genital herpes or other diseases that are spread by sexual contact and diagnose their conditions. The procedure includes visual examinations, blood tests and analyses of discharge or samples taken from lesions.
Programs that identify individuals who have contracted tuberculosis by administering chest x-rays; the Mantoux test, the von Pirquet test or the Vollmer patch test, all of which determine the presence of a tuberculosis infection based on a local inflammatory reaction to a sample of the bacillus which has been injected or rubbed into the skin; or other screening tools.
