Blood Pressure Screening

Programs that measure the pressure existing in the large arteries at the height of a pulse wave and identify individuals whose blood pressure is higher than normal, and who are thereby susceptible to strokes and other conditions that are related to hypertension.

Brain Injury Assessment

Programs that conduct medical tests to determine the extent of brain injuries and the type of treatment and rehabilitation that are needed. Brain injuries may be hereditary, congenital, degenerative or acquired. Acquired brain injuries include central nervous system injury from physical trauma (traumatic brain injuries), anoxia or hypoxic episodes and allergic conditions, toxic substances, and other acute medical/clinical incidents.

Cancer Detection

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.

Cholesterol/Triglycerides Tests

Programs that examine the type and level of fatty substances in the blood as an early indication of coronary heart disease. Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all body's cells. It is an important part of a healthy body because it is used to form cell membranes, some hormones and is needed for other functions. Cholesterol and other fats cannot dissolve in the blood. They have to be transported to and from the cells by special carriers called lipoproteins including low-density lipoprotein (LDL) and high-density lipoprotein (HDL). High levels of LDL cholesterol can build up in the walls of the arteries that feed the heart and the brain and form plaque, a thick hard substance that can clog the arteries. HDL tends to carry cholesterol away from the arteries back to the liver where it is passed from the body. Triglycerides are the chemical form in which most fat exists in food as well as in the body. They are also present in blood plasma and, in association with cholesterol, form the plasma lipids.

Evaluation for Assistive Technology

Programs that assess the current ability to function of people who have disabilities and prescribe or recommend the most appropriate assistive technology product to meet their individual needs including communication/learning aids, control and signaling aids, daily living aids, hearing augmentation aids, mobility aids, prosthetic/orthotic/seating devices, recreational aids, speech aids and/or visual/reading aids.

Eye Examinations

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.

Foot Screening

Programs that evaluate an individual's feet to detect deformities, corns, calluses, bunions, heel spurs, hammertoes, neuromas, plantar warts, ingrown toenails, fungal infections, lesions, areas with loss of sensation or other foot problems. Some foot screenings focus specifically on people with diabetes who often have problems with the nerves and circulation in their feet which can lead to wounds and, in severe cases, amputations, but many are open to all.

Geriatric Assessment

Programs, generally staffed by an interdisciplinary team comprising a geriatrician, a nurse, a social worker and a pharmacist, that evaluate the functional ability, physical health, cognitive and mental health and socioenvironmental situation of older adults, particular those who are frail or chronically ill, to identify health-related problems, develop plans for treatment and follow-up, coordinate care, determine the need for long-term care, and ensure the optimal use of health care resources. Beneficial outcomes may include greater diagnostic accuracy, improved functional and mental status, reduced mortality, decreased use of nursing facilities and acute care hospitals and increased satisfaction with care.

Hearing Screening

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.

HIV Testing

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 counselling 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.

Kidney Screening

Programs that offer any of a variety of tests which determine whether an individual shows signs of decline in kidney function at an early enough stage that progression to more severe forms of kidney disease can be delayed or prevented. Included are blood pressure checks; a blood test for creatinine which estimates the glomerular filtration rate (the rate at which waste is being filtered by the kidneys); and a urine test (urinalysis or microalbumin) which looks for unusually large amounts of protein being excreted. Screening is particularly important for people with diabetes, high blood pressure or a family history of kidney disease, as well as for older adults and people of African, Asian, Latin American, or Pacific Island descent.

Nutrition Assessment Services

Programs that evaluate an individual's nutritional history and dietary intake and develop a plan which ensures that the person's nutritional needs are met. The evaluation includes a review of the individual's food habits and preferences, an assessment of his or her feeding skills and eating problems and an analysis of biochemical and anthropometric variables including the person's height and weight and the fat content of his or her body.
