In 1987, HIV counseling and testing was expanded due to the increased understanding of the scope and severity of the HIV epidemic and the predictive value of the HIV test. Those seeking care for sexually transmitted diseases, family planning, childbirth, or substance abuse were counseled in an attempt to reduce their risk for HIV transmission. Even more so now, the HIV tests have been proven in their reliability and predictive value and public awareness has greatly increased. Early detection of the virus allows the patient to benefit from early antiviral and prophylactic treatment.
Counseling is a direct, personalized, and client-centered intervention designed to help initiate behavior change to avoid infection, or, if already infected, to prevent transmission to others, and to obtain referral to additional medical care, preventive, psychosocial and other needed services in order to remain healthy.
Goals for HIV Counseling and Testing
Objectives
Following is an abbreviated list of the objectives identified to accomplish the above goals.
Necessary Elements
Strict protection of client confidentiality must be maintained for all persons offered and receiving HIV counseling services.
2. Risk Assessment
Client-centered discussion that encourages the client to identify, understand, and acknowledge his or her personal risk for acquiring HIV.
Provides an opportunity for the client to identify his or her risk of acquiring or transmitting HIV and reduce or eliminate behavioral risks.
Involves interpretation that is based upon the test result and the client’s specific risk. Skillful, client-centered counseling is required to reassess behavioral risks which may influence the interpretation of the test results. The client will most often focus on the actual result itself rather than behavioral and preventive messages.
Clients may require referral for physical and psychological evaluations, appropriate therapies (i.e. drug therapies), and support services to enhance or sustain risk reduction behaviors.
Risk Assessment
The risk assessment should include
reason for visit and other relevant concerns, personal circumstances, the
client’s resources and support systems, behavioral and other sources of risk,
demographic and epidemiologic factors that influence risk, client’s awareness of
risk, readiness to change behavior, and receptiveness to available services and
referrals. Risk assessment is not intended solely as a screening tool for client
eligibility for HIV testing. A negotiated risk reduction plan should be
the result and be a realistic, attainable strategy that is developed with the
client to achieve behavior changes to reduce the risk for acquiring or
transmitting HIV. Listen for and address information such as:
The current prevention strategy from the Centers for Disease Control and
Prevention includes offering an HIV test to anyone seeking routine medical care.
This recommendation could go a long way to identify new HIV infections and
prevent spread of the infection. However, it is not always necessary or
appropriate to test an individual and it is unlawful to deny anyone health care
services because they refuse HIV testing. What Else to
Discuss Newer Methods of
HIV testing As part of the assessment the
counselor should ascertain the client’s understanding of HIV transmission and
the meaning of HIV antibody test results. When appropriate and relevant to the
client, the counselor may:
Discuss what the virus is and how it is
transmitted; Discuss what the test results mean and how they are
used in medical management: Negative result—(1)
either the person is not affected, or (2) so recently infected that the test
could not detect the infection;
(Current technology will capture an antibody
response in an average of 25 days. The current maximum to the window period is 3
months. Persons with known exposure should be retested out to 6 months. If a
negative test is received on an individual who is symptomatic and other causes
of immunodeficiency have been ruled out, other types of testing (PCR, NAT) are
recommended. Positive result—the
person is infected with HIV and can transmit it to others; Indeterminate result –
either the sample was compromised or the person may be in the process of
seroconversion. Repeat the test to obtain a definitive result. If still
indeterminate, qualitative PCR or Nucleic Acid Testing is recommended to obtain
a definitive result. Prompt diagnosis and treatment of persons in the acute
phase of HIV infection can alter the prognosis and progression of the disease.
It is highly recommended to consult an infectious disease specialist with HIV
experience in these cases. Discuss the need for retesting
based on exposure history.
Discuss related healthy behaviors, for
example:
In summary, risk assessment information may be obtained by the clinician during
the drug/sexual/medical history prior to or as a component of the counseling
session. Document acknowledged risk behavior, decisions about testing, and
negotiated risk reduction plans in the client’s record.
Limit the use
of alcohol and other drugs;
Obtain family planning
assistance;
Obtain early diagnosis and treatment for STDs, when
appropriate;
Explain authorized disclosures and
anti-discrimination protection;
Discuss bringing a supportive
person of the client’s choice at the time of receiving the test
results.
Assess the client’s concerns and anxieties during the
waiting period. If necessary,
Arrange psychological referral
to assist the client with coping during waiting time;
Provide a
hotline telephone number(s) as a referral option;
Provide a
subsequent counseling session or a follow-up telephone
call.
Guidelines for Informing
Client of Results
Negative Results
:(1) either the person is not affected, or (2) so recently infected that the test could not detect the infection.Ensure that the client understands what the test result
means including Positive HIV Test Result:
Limitations of the
test
Periodic retesting if the client continues to participate
in high risk behaviors
Identify and encourage to continue any
steps already taken by the client to reduce risk and provide positive
reinforcement.
Assist the client in building skills to negotiate risk
reduction activities with current or potential partners through discussion and
role plays
Offer referral for further assistance in avoiding risk
behaviors and maintaining low-risk behaviors
Discuss his/her need and
ability to help partners realize they are also at risk for HIV
infection and make positive persons aware of the availability of partner
notification services at the Health Department.
Advise the client to
refrain from donating blood, plasma, and organs and advise them that future
sexual or needle-sharing partners must be notified before engaging in those
behaviors. Failure to do so constitutes a felony crime in Florida.
Some HIV positive clients may be better prepared to receive positive test results than others. Counseling of patients with positive test results must be directed to the client’s specific circumstances and may require more than one session. Counselors should recognize that the emotional impact of learning about HIV positive results often prevents clients from absorbing other information during this encounter.
Interpretation of HIV-Antibody Test Results
| Special Topic: Late Testing of HIV |
| Patients tested late in an
infection are those who acquire AIDS when diagnosed within one year of
HIV. Of those diagnosed with AIDS, 43% are found to be tested
late. Those tested late miss opportunities for treatment and
prevention of HIV. Most of those tested late sought testing because
of illness. Those tested early tested for reasons including
perceived risk, desire to know their HIV status, and routine check-up in
addition to illness
During the time between HIV infection and diagnosis, infected persons can transmit HIV to others when they engage in practices that put their partners at risk. HIV transmission could be reduced by increasing awareness of HIV status through early testing. According to a CDC report comparing early and late testers of HIV, late testers are more likely black or Hispanic, less educated, and exposed to HIV through heterosexual contact. Many of these late testers may have been previously tested for HIV one or more times. Because of this, CDC is now focusing prevention efforts towards communities more highly infected with HIV. (g)

A test for HIV 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.
The sensitivity (the probability that a test will be positive when the infection is present) of the currently licensed EIA tests is 99% or greater when performed under optimal laboratory conditions. This makes the chance of a false-negative result remote, except during the first few weeks of infection before antibody is detectable.
Partner Notification/Contact Tracing
Sexual partners and those who share needles with
HIV-infected persons are at risk for HIV infection and should be routinely
counseled and tested for HIV antibody. Persons who are HIV-antibody positive
should be instructed in how to notify their partners and to refer them for
counseling and testing. If they are unwilling to notify their partners or if it
cannot be assured that their partners will seek counseling, physicians or health
department personnel can assist confidential procedures to assure that the
partners are notified.
Every reasonable effort should be made to
improve confidentiality of test results. The confidentiality of related records
can be improved by a careful review of actual record-keeping practices and by
assessing the degree to which these records can be protected under applicable
state laws. State laws should be examined and strengthened when found necessary.
Because of wide scope of "need-to-know" situations, because of the possibility
of inappropriate disclosures, and because of established authorization
procedures for releasing records, it is recognized that there is no perfect
solution to confidentiality in all situations.
Persons are more likely
to participate in counseling and testing programs if they believe they will not
experience negative consequences in areas such as employment, school admission,
housing, and medical services should they test positive. There is no known
medical reason to avoid an infected person in these and ordinary social
situations since the cumulative evidence is definitive that HIV infection is not
spread through casual contact. It is essential to the success of counseling and
testing programs that people who are tested or HIV programs are not subjected to
inappropriate discrimination. (CDC, HIV/AIDS Among U.S. Women, May 2002).
