Disease/Disability Specific Screening/Diagnosis

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.

BMI/Body Composition Screening

Programs that evaluate an individual's height, weight and body composition as a means of assessing overall health and fitness. Included are programs that calculate a person's Body Mass Index (BMI), a figure that is based on the weight (in kilograms) divided by the height (in meters) squared and interpreted using a table which shows value ranges for people who are underweight, have normal weight or are overweight; and those that look at the individual's body weight in terms of percentage of body fat, lean body mass (including organs, muscle and bone) and percentage of body water. Personalized recommendations for nutrition and exercise may also be provided for people with underdeveloped musculature or excessive body fat. These tests may be provided as components of nutrition assessment and prescription services or physical fitness assessment programs, but are often available as separate screenings.

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 to determine whether an individual has the COVID-19 virus. Health care professionals authorize who should be tested based on a combination of the individual's symptoms (though someone with COVID may be asymptomatic), underlying medical conditions and risk of exposure to the virus. Samples can be collected through a nose swab, throat swab or saliva sample. Once the sample is taken, it is put into a sterile container and sent to the lab where the sample is analyzed and copies are made of the virus' RNA. The machine attempts to match the person's RNA with the coronavirus RNA to determine a positive or negative result.

COVID-19 Test Home Collection Kits

Programs that provide kits which allow prescreened individuals to collect a test sample at home to avoid an in-person visit to a COVID test site. Pre-screening is done using an online questionnaire that is reviewed by a health care provider. The individual then uses the enclosed nasal and/or throat swab, packs the sample(s) up and ships them to the designated laboratory for analysis. (Some kits may instead require a blood sample collected by finger pricking, or other approved methods of sampling.) Results are generally available online within 24-48 hours. If the test shows positive results, the program may offer a telehealth consult to guide the individual through any next steps. The test is recommended for individuals age 18 and older who have been in close contact with someone who has become ill, or who may have been exposed to COVID-19 by living, working or gathering in close proximity to others. The test is also recommended for people who show symptoms of the virus (elevated temperature, flu-like symptoms, loss of taste or smell, worsening cough or sore throat, or shortness of breath). The tests are not intended to be a substitute for those seeking or needing professional diagnosis, treatment or medical advice, and may or may not be authorized by the U.S. Food and Drug Administration.

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 Screening

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

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 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.

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.

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.
