According to the UNAIDS 2023 Global AIDS Update report, as of the end of 2022, there were an estimated 39 million people living with HIV worldwide, and 630,000 people died from AIDS-related illnesses. In our country, it is estimated that about 16% of those infected are either undiagnosed or unaware of their infection status. These undiagnosed individuals are currently the primary source of new HIV infections.
Why Get Tested Regularly? How Often Should You Get Tested?
Testing is the only way to determine your HIV status. To confirm whether you are infected with HIV, you must undergo a professional HIV test. For individuals with multiple sexual partners or frequent partner changes, achieving 100% safety through protection is challenging. Therefore, regularly testing for HIV antibodies and staying informed about your health status is essential.
Experts recommend getting tested twice a year, with testing every three months being optimal. If you have engaged in anal sex, whether or not a condom was used, you should definitely get tested.
Why You Should Get an HIV Test: Importance, Benefits, and What to Know
Importance of Early Detection and Treatment : Testing for HIV is essential for early detection and treatment. Early identification of the virus allows for effective management, improving long-term health outcomes and reducing the risk of complications.
Preventing the Spread of HIV : By knowing your HIV status, you can take steps to protect yourself and others, thereby helping to prevent the transmission of the virus.
Monitoring and Peace of Mind : For those already diagnosed with HIV, regular testing is crucial for monitoring the virus's progression and assessing treatment effectiveness. Additionally, getting tested provides peace of mind, clarifies health status, and aids in making informed decisions about health and relationships.
Understanding HIV Testing
Types of HIV Tests
HIV tests determine if you are infected with the Human Immunodeficiency Virus. There are several types of tests:
- Antibody Tests: These are the most common and reliable, detecting HIV antibodies in blood or oral fluids.
- Antigen/Antibody Tests: These identify both HIV antibodies and antigens through blood drawn from a vein.
- Nucleic Acid Tests (NATs): These detect HIV RNA in the blood and are used for high-risk cases or very early detection.
Who Should Get an HIV Test
High-Risk Individuals : Individuals at high risk include those who have had unprotected sex with multiple partners or with partners whose HIV status is unknown, as well as those who share needles or syringes for drug use.
Individuals with Certain Health Conditions : Testing is also recommended for those diagnosed with other sexually transmitted infections (STIs) and pregnant women to prevent mother-to-child transmission and ensure appropriate care.
Individuals with Symptoms of HIV : Symptoms such as fever, rash, swollen lymph nodes, and sore throat, occurring 2-4 weeks after exposure, may indicate acute HIV infection. Persistent symptoms like night sweats, weight loss, and chronic diarrhea also warrant testing.
Individuals with Known Exposure : Those who have had recent potential exposure to HIV, through unprotected sex or sharing needles, should get tested. Additionally, individuals with occupational exposure, such as healthcare workers with needle-stick injuries, should consider testing.
Routine Testing for Specific Groups : Certain groups, such as pregnant women and those living in high HIV prevalence areas, should undergo routine testing. Adolescents and young adults engaged in high-risk behaviors should also be tested regularly.
General Population Recommendations : Routine HIV testing is advised for everyone at least once in their lifetime, particularly if sexually active, as part of regular health check-ups to ensure broader screening and early detection.
When to Get Tested
Timing for High-Risk Activities : Get tested after engaging in high-risk activities or if you suspect exposure to HIV. Immediate testing is recommended, with follow-up tests based on the test’s window period.
Regular Testing for High-Risk Individuals : For those at high risk, regular testing, such as annually or more frequently, is advisable for ongoing monitoring and early detection.
Benefits of Testing
Early Detection and Treatment : Early diagnosis through testing allows for timely management of HIV, improving health outcomes and preventing further transmission.
Peace of Mind : Testing provides reassurance and helps individuals take control of their health, reducing anxiety and aiding in making informed decisions.
Confidentiality and Support
Ensuring Confidentiality : HIV testing services ensure that results are kept confidential, shared only with you or with your consent.
Available Support Services : Support services, including counseling and resources, are available to help you understand your results and make informed decisions.
Deciding to Get Tested
When to Consider Testing : Consider getting tested if you have engaged in high-risk behaviors, experienced symptoms, or as part of routine health screenings and pregnancy care.
Testing Options : You can get tested through healthcare providers, public health clinics, community organizations, or home test kits. Most tests do not require special preparation, but follow any specific instructions from the testing facility.
Preparing for the Test : Ensure the testing location respects your privacy and provides counseling services. During the test, a healthcare professional will either draw blood or perform an oral swab. The procedure is quick and minimally invasive, with results available in a few days to weeks, depending on the test type and location.

Procedure: Follow the kit instructions to collect a sample (usually oral fluid or a fingerstick blood sample).
To use an HIV test kit, first, make sure you have read and understood the instructions provided by the manufacturer. Begin by collecting the sample as directed, which could be blood, oral fluid, or urine depending on the type of test. Next, apply the sample to the test device and follow the specified procedure for processing, which may involve waiting for a certain period. Finally, interpret the results according to the instructions, ensuring you adhere to any guidelines for reading and understanding the test outcomes.

Negative Test Results
If you receive a negative result from an HIV test kit, it indicates that no HIV was detected at the time of testing. However, if you were recently exposed to HIV, it is crucial to follow up with additional testing to confirm the result's accuracy.
Positive Test Results
A positive result means that HIV was detected, and confirmatory testing is required to verify the diagnosis. Once confirmed, you should discuss treatment options, preventive measures, and lifestyle adjustments with your healthcare provider.
Addressing False Results
While false results are rare, they can occur. If there is a possibility of a false result, additional tests or retesting may be necessary to ensure the accuracy of your diagnosis.
Next Steps After Receiving Results
If your result is negative, continue with regular health check-ups and maintain safe practices to prevent HIV infection. If your result is positive, seek medical care to start antiretroviral therapy (ART) for managing the virus. Inform your sexual partners so they can also get tested and take preventive measures. Additionally, access support services such as support groups and counseling for emotional and social support.
Follow-Up: Positive results should be confirmed with a healthcare provider.
What Does the HIV Antibody Screening Test Result Mean?
If the test result is abnormal, it indicates a possible HIV infection and requires confirmatory testing.
If the test result is negative, there are two possibilities:
1. No Infection: You are not infected with HIV, but you should continue to avoid unsafe practices in the future.
2. Window Period: You might be in the "window period," where the infection is not yet detectable. It is recommended to get tested again after 6 weeks.
