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.

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.

COVID-19 Diagnostic Tests

Public health laboratories that conduct diagnostic testing for people who have symptoms of the novel coronavirus that causes COVID-19. People who have been in close contact with someone with COVID-19 or are a resident in a community where there is ongoing spread of the virus and develop symptoms are being advised to call their health care provider and tell them about their symptoms and exposure, at which point a decision will be made as to whether they need to be tested. Patients who require a test will have a swab inserted through their nose to reach what is known as the nasopharyngeal region where cells are collected. If the patient is calm, the swabbing takes 10 seconds or so and is not painful. A jittery patient can make things more difficult. Once the sample is taken, it is put into a sterile container and sent to a lab where a chemical pulls the cells off the swab and turn the sample into a liquid form, which is put into a machine that makes multiple copies of the virus' RNA. The machine attempts to match the person's RNA with the coronavirus RNA to determine a positive or negative result.

Dental Screening

Programs that provide dental examinations to detect tooth decay and periodontal problems, and oral hygiene information; but which refer out for cleaning, fillings, extractions and other necessary dental care.

Diabetes Screening

Programs that administer tests which determine whether an individual has diabetes, a disorder in which the pancreas produces too little insulin with the result that the body in unable to adequately metabolize sugar.

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.

Eye Screening

Programs that offer screening procedures that identify people who have targeted eye diseases or vision deficiencies that may require further examination.

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 Aid Evaluations

Programs that determine the proper amplification equipment for individuals who have hearing impairments and/or which evaluate the adequacy of present equipment.

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.

Hepatitis Testing

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.

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 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.

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.

Lead Poisoning Screening

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.

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.

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.

Sickle Cell Screening

Programs that identify individuals who have sickle cell anemia or who are carriers of that disease through laboratory analysis of their blood to determine whether the abnormal crescent-shaped erythrocytes indicative of the disease are present.

Tuberculosis Screening

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.
