Challenges In Hiv Testing
4.3.1 HIV Testing in the “window period”
The window period is the time after acquisition of HIV infection when the individual is highly infectious but tests negative on HIV antibody screening because antibodies are not immediately produced. As shown in Figure 4, the timelines associated with the window period have changed with the evolution of more sensitive antibody screening tests. While 1st generation tests detected HIV antibody an average of 60 days following exposure the 4th generation combination tests permit detection of acute HIV infection during the viremic phase. This reduces the window period to approximately 15 to 20 days. Making the diagnosis as early as possible can help prevent onward transmission of the virus, since the person is most infectious during this period. Some jurisdictions provide NAAT testing for high-risk clients , in an effort to identify very early HIV infection.
4.3.2 Indeterminate results during the window period
4.3.3 Confirmatory Testing
The Western Blot assay is not as sensitive as the 3rd and 4th generation screening tests and may yield indeterminate results during the window period. New algorithms employing NAAT as a confirmatory test are currently being evaluated.

How Much Do Hiv Tests Cost
Unlike rapid tests, blood tests for HIV are covered by Medicare, which means your doctor can order the test free of charge for you.
If you are not eligible for Medicare, you may also be able to claim some of the testing costs through private health insurance. Check with your provider to see if youre eligible.
What Happens If I Test Positive For Hiv
If your initial test is positive for HIV antibodies, then additional testing is required to confirm that the first one was accurate. Sometimes this involves a second blood test.
When you are first diagnosed you will probably experience strong emotions. During this time, do not try to cope on your own. Seek support by speaking with your doctor, or contact your local community organisation. They have trained peer workers available to help you through the initial stages of a positive diagnosis, but also through your journey of living well with HIV.
Part of testing best practice includes pre- and post-test counselling. Post-test counselling is important, regardless of the outcome. If you test positive, counselling can provide emotional support, further information about living with HIV, and referrals to support services.
If the test is negative, counselling can provide education about HIV and how to reduce your HIV risk in the future. are community organisations that provide support and advocacy for people with HIV. Peer workers are also available to help you navigate living with HIV.

Tips For Taking Your Medications
Besides knowing “how does HIV turn into AIDS?” You may want to know how to take the medications correctly. Medications for HIV need to be taken consistently. Otherwise, the virus can become resistant to the drugs and reproduce itself faster. Here are a few tips to help you take your medications in the right way and prevent an early onset of AIDS:
- Start taking your medication at the right time. When you start taking antiretroviral drugs, you will need to keep taking them for the entire life. So make sure you are ready to this serious commitment. Before starting taking ARVs, you can test yourself for consistency by taking a piece of candy at a specific time every day. Your performance with this will help you know whether you are ready to start taking the drugs.
- Have a reminder. You can choose to set an alarm or a reminder on your phone or simply check off a to-do list. This will help you always remember to take your drugs.
- Store the drugs correctly. Ideally, you should keep them at a spot where you can always see them, such as near to your bed. When travelling, you should have a container with the medications.
- Have sufficient amounts of the medications at all times. It is important to keep more than your need of the drugs at all times in case anything happens. Whenever you almost run short of the drugs, you need to visit the pharmacist to avoid a last minute rush.
How Do I Avoid Getting Hiv During Sex
HIV is spread through contact with blood or sexual fluids , usually during vaginal and anal sex. So the only 100% certain way to avoid HIV is to not have vaginal or anal sex.
But most people do have sex at some point in their lives, so learning about HIV prevention and knowing how to have safer sex is important. Using condoms REALLY lowers your risk of getting HIV. If youre going to have sex, using condoms every single time is the best way to protect yourself from HIV. Theres also a daily pill you can take called PrEP that can help prevent HIV. Your doctor or nurse can tell you if PrEP is right for you.
Some sexual activities are safer than others when it comes to getting HIV. These activities are no risk theyve never caused a reported case of HIV:
having oral sex with a condom or dental dam
using clean sex toys
These activities are lower risk theyve only caused a few reported cases of HIV :
“French or deep kissing
vaginal sex with a condom and/or PrEP
anal sex with a condom and/or PrEP
oral sex without a condom or dental dam
These activities are high risk millions of people get HIV this way:
Theres no vaccine that protects against HIV, but lots of people are working on making one. And there are medicines that can help prevent HIV.

How To Delay The Progression Of Hiv To Aids
How does HIV turn into AIDS? Is it possible to delay the process? Yes. There is currently no cure for AIDS, but the condition can be delayed to give the person a longer period of good health. Each class of the medications works differently to control the virus. It is advisable to use a combination of three drugs from two classes.
- Non-nucleoside reverse transcriptase inhibitors . This class includes drugs like efavirenz, etravirine and nevirapine. These drugs work by disabling a protein required by the HIV virus to reproduce.
- Nucleoside or nucleotide reverse transcriptase inhibitors . This class of drugs includes abacavir. The drugs work by producing faulty protein that resemble those used by the HIV virus to reproduce.
- Protease inhibitors . This class includes atazanavir, darunavir, fosamprenavir and indinavir. These drugs inhibit protease, a protein required by the HIV virus to reproduce.
- Entry or fusion inhibitors. Entry inhibitors include enfuvirtide and maraviroc. These drugs delay the development of AIDS by inhibiting the entry of the HIV virus into the CD4 cells.
- Integrase inhibitors. Integrase inhibitors include raltegravir, elvitegravir and dolutegravir. Integrase is a protein used by the HIV virus to insert its DNA into the CD4 cells. These drugs function by inhibiting it.
When to Start Drugs
All people with HIV should be on antiretroviral drugs. However, drugs are particularly necessary in these situations:
Possible Side Effects
Why Is Hiv Testing Important
Knowing your HIV status can help keep youand otherssafe.
If you are HIV negative:
A negative HIV test result shows that you do not have HIV. Continue taking steps to avoid getting HIV, such as using condoms during sex and, if you are at high risk of getting HIV, taking medicines to prevent HIV . For more information, read the HIVinfo fact sheet on The Basics of HIV Prevention.
If you are HIV positive:
A positive HIV test result shows that you have HIV, but you can still take steps to protect your health. Begin by talking to your health care provider about antiretroviral therapy . People on ART take a combination of HIV medicines every day to treat HIV infection. ART is recommended for everyone who has HIV, and people with HIV should start ART as soon as possible. ART cannot cure HIV, but HIV medicines help people with HIV live longer, healthier lives.
A main goal of ART is to reduce a persons viral load to an undetectable level. An undetectable viral load means that the level of HIV in the blood is too low to be detected by a viral load test. People with HIV who maintain an undetectable viral load have effectively no risk of transmitting HIV to their HIV-negative partner through sex.

Appendix D: Natural History Of Hiv Infection
Human immunodeficiency virus is a retrovirus that infects the cells of the immune system. It is transmitted via exposure to body fluids that contain lymphocytes or free infectious viral particles . The routes of infection are: unprotected sexual intercourse, sharing of injection-drug use equipment and from an HIV-infected mother to her unborn child. Although rare, HIV can also be transmitted through an occupational exposure such as a needlestick injury or other event where blood to blood exposure could occur. All blood and blood products used in Canadian healthcare settings now undergo extensive screening for HIV prior to use, so new infections related to their use have been virtually eliminated .
The virus can enter the body through unprotected mucous membranes where cells may become infected with HIV . The presence of a sexually transmitted infection can enhance HIV transmission because of lesions and/or an increased number of lymphocytes. Using a needle contaminated with HIV-infected blood deposits the virus directly into the blood system, where infection of lymphocytes will occur. Transmission from mother to child can take place in utero, during delivery through exposure to the mother’s blood or vaginal secretions, and through breast milk . Seroconversion occurs when an individual changes from being HIV antibody negative to HIV antibody positive.
Why Its Important To Test
If you have HIV, finding out means you can start treatment, stay healthy and avoid passing the virus onto anyone else. The sooner you start treatment, the less likely you are to become seriously ill. People who are diagnosed early and get on effective treatment can expect to live a normal lifespan.
Once youre on effective treatment and your viral load is undetectable then you can’t pass the virus on to anyone else.
If you wait to test, the virus could do a lot of damage. There is a lot of support available for people who test positive.

Appendix A: Ethical And Professional Considerations
Policy concerning the ethical and professional roles and responsibilities of care providers is informed by the providers’ respective institutional code of ethics as well as the professional colleges under which they are governed.
The following is designed to complement, not supersede, existing codes of conduct or jurisdictional health policies and regulations or any applicable laws and regulations of the jurisdiction.
Where To Access Testing Services
Standard HIV testing can generally be accessed through any health provider across the country. Each province is responsible for licensing the laboratories that provide HIV screening and confirmatory testing in its jurisdiction. In general, all provincial Public Health Laboratories provide both screening and confirmatory testing. Reference and specialized services, when required, are provided by the National HIV Reference Serology Laboratory after consultation with the provincial laboratory. It is advisable to contact your testing laboratory to confirm the specimen collection details.
Anonymous or POC testing locations can be found by calling a local HIV/AIDS hotline .

Are People Able To Understand Test Instructions And Use Self
A review identified 25 studies in which people used self-tests, with their results compared with those of a healthcare worker testing them at the same time. The original studies were done in a mix of North American, African, European and Asian countries. Fifteen studies used oral fluid-based tests, six used blood-based tests and four used both oral and blood specimens. Of note, several studies were evaluating professional assays that had not been adapted for use as self-tests performance could be better in commercially marketed tests.
The researchers found that most people could reliably and accurately use rapid tests. Using a statistical approach known as Cohens kappa in which 1 represents perfect agreement between the results of a self-tester and a trained health worker and less than 1 represents less than perfect agreement, results were highly concordant. The Cohens kappa was 0.98 in studies in which users first received a demonstration of how to do the self-test or to interpret its result. In studies in which this was not provided, it was 0.97. This means that in only a small minority of cases the self-tester and the healthcare worker got results that were different from each other.

Who Should Be Tested For Hiv And How Frequently
It is recommended that the consideration of HIV testing be made a component of routine care. In general, care providers should take an active approach to HIV testing, offering HIV testing to clients whether or not clients have asked for a test. In the provision of routine medical care, and in discussion with the client, care providers should consider whether there is a benefit to an HIV test.
HIV testing is associated with several advantages:
- a negative test result is an opportunity for clients to take an active role in remaining HIV negative
- the early detection of HIV, especially at the acute stage, can improve outcomes for individuals and prevent further transmission of HIV
- detection at any stage of the disease, prior to wasting and dementia, is an opportunity to initiate lifesaving treatment and other related healthcare services
- opportunities arise for conversations with clients about risk-reduction strategies
2.1.1 Testing recommendations
An in-depth comprehensive HIV behavioural risk assessment is not a requirement for offering an HIV test. An assessment that the client understands how HIV is transmitted, the implications of testing , and how to interpret the test results is sufficient.
For occasions when clients may not be able to accurately estimate their risk, the guide includes more detailed guidance in Appendix B for conducting rapid risk assessments and a more detailed technical review of HIV transmission risks can be found in Appendix C.
2.1.2 Couples testing
Factors That Increase Risk For Hiv Infection
Sexually active but no history of being tested for HIV.
Use of shared drug equipment with a partner whose HIV status is unknown.
Unprotected anal or vaginal intercourse with a partner whose HIV status is unknown.
Multiple and/or anonymous sexual partnering.
For men, a history of sex with other men.
Diagnosis of other STI, hepatitis B or C.
Sexual activity, sharing of drug-use equipment, or receipt of blood or blood products for people originating from, or who have travelled to, regions where HIV is endemic.
Receipt of blood or blood products in Canada prior to November 1985.

Hiv And Health Insurance Among Black People
Despite increased access to healthcare under the Affordable Care Act, 1 of every 9 Black people is without insurance. Black trans people, especially Black trans women, often experience hostility in health settings. Black transmasculine people are often excluded from HIV discourse despite testing positive at higher rates in comparison to the general population.
Poor community access to health insurance, provider hostility, and lack of provider knowledge about trans communities may increase a person’s likelihood of testing HIV-positive. Among Black MSM, the lack of insurance increases the risk of HIV by 2.5 times compared to those who have insurance.
Changing Attitudes About Hiv
When someone is diagnosed with HIV, other people may have negative attitudes and beliefs about that person’s behaviour, lifestyle or circumstances in life. These negative associations form what’s called stigma, an experience that can decrease quality of life because it includes:
Efforts to end stigma will help to:
- prevent new infections
- ensure that people living with HIV receive the care, treatment and support they need
