It only takes a few minutes to get tested for HIV, and this step can make all the difference. Many people go years without knowing they have HIV because the infection can go without any symptoms. However, it is the asymptomatic course that makes HIV insidious \u2013 the later it is detected, the more difficult it is to maintain immunity.<\/p>\n

Fortunately, diagnostics have become accessible, fast, and accurate. Modern methods allow us to detect HIV at an early stage and begin treatment before complications occur.<\/p>\n

Two keys to diagnosis: antibodies and the virus<\/strong><\/h3>\n

After HIV enters the body, the immune system begins to produce specific antibodies. Most HIV tests are based on their detection. But there are also methods that determine the genetic material of the virus itself - this is especially important in the early stages, when antibodies have not yet been formed.<\/p>\n

Typical diagnostic methods:<\/p>\n

    \n
  • \n

    ELISA (enzyme-linked immunosorbent assay)<\/strong> \u2014 looking for antibodies to HIV<\/p>\n<\/li>\n

  • \n

    PCR (polymerase chain reaction)<\/strong> \u2014 detects viral RNA<\/p>\n<\/li>\n

  • \n

    4th generation combined tests<\/strong> \u2014 both antibodies and p24 antigen are detected<\/p>\n<\/li>\n

  • \n

    Rapid tests<\/strong> \u2014 saliva or capillary blood samples, results in 15\u201320 minutes<\/p>\n<\/li>\n<\/ul>\n

    The first signs of the virus can appear in the results as early as 10 days after infection (PCR), but for most tests, the optimal time is 3\u20134 weeks after possible contact.<\/p>\n

    What you should know about the "window period"\u00ab<\/strong><\/h3>\n

    There is a period of time after infection when the virus is present but may not be detected by the test. This is called the \u00abseronegative window.\u00bb Its duration depends on the type of test:<\/p>\n

      \n
    • \n

      PCR \u2014 10\u201314 days<\/p>\n<\/li>\n

    • \n

      ELISA \u2014 3\u20136 weeks<\/p>\n<\/li>\n

    • \n

      express tests \u2014 1\u20132 months<\/p>\n<\/li>\n<\/ul>\n

      That is why, if the test is done too early, it is recommended to repeat it after 12 weeks to obtain a final result.<\/p>\n

      \"A<\/p>\n

      Who should get tested regularly?<\/strong><\/h3>\n

      HIV has no face. It can be caught with a single unprotected contact or during household contact with someone else's blood. Regular testing is indicated for:<\/p>\n

        \n
      • \n

        all sexually active people - at least once a year<\/p>\n<\/li>\n

      • \n

        with new sexual partners<\/p>\n<\/li>\n

      • \n

        for couples before planning a pregnancy<\/p>\n<\/li>\n

      • \n

        medical workers, donors, pregnant women<\/p>\n<\/li>\n

      • \n

        people who have had contact with blood or injecting drug use<\/p>\n<\/li>\n<\/ul>\n

        The presence of flu symptoms, rash, lymphadenopathy, or chronic fatigue after possible exposure is another reason for testing.<\/p>\n

        Diagnosis is not the end, but the beginning of treatment<\/strong><\/h3>\n

        A positive result does not mean that you have AIDS. It means that the virus is present and action is needed. Modern antiretroviral therapy (ART):<\/p>\n

          \n
        • \n

          stops HIV replication<\/p>\n<\/li>\n

        • \n

          reduces viral load to an undetectable level<\/p>\n<\/li>\n

        • \n

          restores immunity<\/p>\n<\/li>\n

        • \n

          reduces the likelihood of virus transmission to zero<\/p>\n<\/li>\n<\/ul>\n

          Patients with HIV can work, have children, and live just as long as those without this diagnosis \u2014 if they start treatment on time.<\/p>\n

          Advantages of modern tests<\/strong><\/h3>\n
            \n
          • \n

            quick results (some in 15 minutes)<\/p>\n<\/li>\n

          • \n

            high sensitivity (over 99%)<\/p>\n<\/li>\n

          • \n

            accessibility in public and private institutions<\/p>\n<\/li>\n

          • \n

            free of charge in many medical centers<\/p>\n<\/li>\n

          • \n

            confidentiality is guaranteed by law<\/p>\n<\/li>\n<\/ul>\n

            For most tests, 1\u20132 ml of venous blood is sufficient. The test is performed on an empty stomach or 2\u20133 hours after eating. Alcohol and intense exercise should be avoided before the test.<\/p>\n

            Awareness is the key to prevention<\/strong><\/h3>\n

            According to WHO, up to 40% people with HIV do not know their status. Testing is not only about yourself, but also about the safety of your partner. Successful programs to reduce the spread of infection are based on open, regular and voluntary diagnostics.<\/p>\n

            An HIV blood test is not fear, but concern. Concern for your health, your loved ones, and your future. This is one of the most important steps that should be taken at least once a year \u2014 calmly, consciously, and for the sake of life.<\/p>","protected":false},"excerpt":{"rendered":"
