Human immunodeficiency virus HIVthe causative agent of acquired immunodeficiency syndrome AIDS and related clinical manifestations, has been shown to be spread by sexual contact; by parenteral exposure to blood most often through intravenous IV drug abuse and, rarely, by other exposures to blood; and from an infected woman to her fetus or infant.
Persons exposed to HIV usually develop detectable levels of antibody against the virus within weeks of infection. The presence of antibody indicates current infection, though many infected persons may have minimal or no clinical evidence of disease for years.
Counseling and testing persons who are infected or at risk for acquiring HIV infection is an important component of prevention strategy 1.
Most of the estimated 1. The primary public health purposes of counseling and testing are to help uninfected individuals initiate and sustain behavioral changes that reduce their risk of becoming infected and to assist infected individuals in avoiding infecting others.
Along with the potential personal, medical, and public health benefits of testing for HIV antibody, public health agencies must be concerned about actions that will discourage the use of counseling and testing facilities, most notably the unauthorized disclosure of personal information and the possibility of inappropriate discrimination.
Priorities for public health counseling and testing should be based upon providing ready access to persons who are most likely to be infected or who practice high-risk behaviors, thereby helping to reduce further spread of infection.
There are other considerations for determining testing priorities, including the likely effectiveness of preventing the spread of infection among persons who would not otherwise realize that they are at risk. Knowledge of the prevalence of HIV infection in different populations is useful in determining the most efficient and effective locations providing such services.
After counseling and testing are effectively implemented in settings of high and moderate prevalence, consideration should be given to establishing programs in settings of lower prevalence. Interpretation of HIV-Antibody Test Results A test for HIV antibody is considered positive when a sequence of tests, starting with a repeatedly reactive enzyme immunoassay EIA and including an additional, more specific assay, such as a Western blot, are consistently reactive.
Given this performance, the probability of a false-negative test result is remote, except during the first weeks after infection, before antibody is detectable. Repeat testing of specimens initially reactive by EIA is required to reduce the likelihood of false-positive test results due to laboratory error.
To further increase the specificity of the testing process, laboratories must use a supplemental test--most often the Western blot test--to validate repeatedly reactive EIA results.
The sensitivity of the licensed Western blot test is comparable to that of the EIA, and it is highly specific when strict criteria are used for interpretation. Under ideal circumstances, the probability that a testing sequence will be falsely positive in a population with a low rate of infection ranges from less than 1 inMinnesota Department of Health, unpublished data to an estimated 5 in3,4.
Laboratories using different Western blot reagents or other tests or using less stringent interpretive criteria may experience higher rates of false-positive results.
Laboratories should carefully guard against human errors, which are likely to be the most common source of false-positive test results. All laboratories should anticipate the need for assuring quality performance of tests for HIV antibody by training personnel, establishing quality controls, and participating in performance evaluation systems.
Health department laboratories should facilitate the quality assurance of the performance of laboratories in their jurisdiction.
Guidelines for Counseling and Testing for HIV Antibody These guidelines are based on public health considerations for HIV testing, including the principles of counseling before and after testing, confidentiality of personal information, and the understanding that a person may decline to be tested without being denied health care or other services, except where testing is required by law 5.
Counseling before testing may not be practical when screening for HIV antibody is required.
This is true for donors of blood, organs, and tissue; prisoners; and immigrants for whom testing is a Federal requirement as well as for persons admitted to state correctional institutions in states that require testing.
When there is no counseling before testing, persons should be informed that testing for HIV antibody will be performed, that individual results will be kept confidential to the extent permitted by law, and that appropriate counseling will be offered.
Individual counseling of those who are either HIV-antibody positive or at continuing risk for HIV infection is critical for reducing further transmission and for ensuring timely medical care. Persons who may have sexually transmitted disease.
All persons seeking treatment for IV-drug abuse or having a history of IV-drug abuse should be routinely counseled and tested for HIV antibody. Medical professionals in all health-care settings, including prison clinics, should seek a history of IV-drug abuse from patients and should be aware of its implications for HIV infection.
In addition, state and local health policy makers should address the following issues: Treatment programs for IV-drug abusers should be sufficiently available to allow persons seeking assistance to enter promptly and be encouraged to alter the behavior that places them and others at risk for HIV infection.
Outreach programs for IV-drug abusers should be undertaken to increase their knowledge of AIDS and of ways to prevent HIV infection, to encourage them to obtain counseling and testing for HIV antibody, and to persuade them to be treated for substance abuse.
Persons who consider themselves at risk.
All persons who consider themselves at risk for HIV infection should be counseled and offered testing for HIV antibody. Women of childbearing age. All women of childbearing age with identifiable risks for HIV infection should be routinely counseled and tested for HIV antibody, regardless of the health-care setting.
Women are at risk for HIV infection if they: Have used IV drugs. Have engaged in prostitution. Have had sexual partners who are infected or are at risk for infection because they are bisexual or are IV-drug abusers or hemophiliacs. Are living in communities or were born in countries where there is a known or suspected high prevalence of infection among women.Dec 18, · The relative evidence for H1 versus H0 is / = In other words, based on the observed data, and a model for the null and a model for the alternative hypothesis, it is 16 times more likely that the alternative hypothesis is true than that the null hypothesis is true.

Autobiographical memory is a memory system consisting of episodes recollected from an individual's life, based on a combination of episodic (personal experiences and specific objects, people and events experienced at particular time and place) and semantic (general knowledge and facts about the world) memory.
It is thus a type of explicit memory. SELSE The 14th Workshop on Silicon Errors in Logic – System Effects. April , Northeastern University, Boston, Massachusetts.
