Given its status as being a widespread disease and major concern for medical foundations around the world, it should come as no real surprise that HIV treatment and detection have come a long way since their inception. Over time, new methodologies have emerged to highlight improvements across several HIV testing metrics: speed, reliability, accuracy, and applicability have all increased as new generations of ชุดตรวจ HIV ร้านขายยา emerge.
Exactly what does this pertain to you? Plenty! Doctors and medical professionals everywhere increasingly encourage routine HIV testing as a means of ensuring personal health insurance and addressing the spread of HIV. Remember, HIV can survive in their host without obvious symptoms for long time periods. Seeking this in a trusted facility not only protects your future health, but also that relating to all your family members and intimate partners.
No matter what test you take, it’s mandatory to follow along with up a good result with alternative tests-this drastically reduces the chance of a fluke inside the test. You should also know that lots of the home HIV testing kits on the market haven’t received FDA approval and therefore are rife with inaccuracy. Using that in mind, here are a few particulars on various professional HIV testing options that are offered to you:
Antibody Tests – These are the most frequent HIV testing procedures for routine screening. They take advantage of the simple fact that your body naturally produces anti-infection proteins called antibodies responding to HIV infection. This method detects antibodies from a blood, saliva, or urine sample. Usually an enzyme-linked immunosorbent assay (ELISA) is the preferred antibody test due to its high sensitivity.
There are a few important considerations with antibody tests. Because the body will take time to build up antibodies, there is a “window period” during which HIV-positive individuals may receive false negative results because they tested too soon. For this reason, this technique of HIV tests are recommended 3 months after potential exposure. If the HIV-positive mother has a child, their antibodies will be passed on and retained inside the baby’s body for as much as 18 months; other tests are recommended within this case. Similarly, people who have took part in HIV vaccine trials should take multiple tests to minimize the chance of false results.
Rapid HIV Tests – These operate on the same principles as antibody tests with much quicker turnaround. They take under an hour and often require no follow-up visit; each of the analysis is done on-site by healthcare professionals. These are easier for medical staff to conduct and minimally invasive for the patient. These are generally suited to urgent medical situations or places that clients are unlikely to return to check on their results.
Antigen Tests – These tests seek substances from your HIV virus itself, called antigens. Specifically, they seek the P24 protein produced during the early stages of HIV infection. This variety of testing isn’t very sensitive and isn’t particularly recommended itself. Instead, doctors administer hybrid HIV testing by combining antigen tests with standard antibody tests to improve accuracy while reducing the “window period.” Called fourth-generation tests, these new trends in this particular testing will show with dveaos frequency as medical technology consistently advance.
PCR Tests – Polymerase Chain Reaction (PCR) tests also detect HIV infection early by testing for that genetic material in the virus. Also known as the viral load test or nucleic acid amplification testing (NAAT), PCR HIV tests are suited for screening blood supplies or newborns and is also effective within two or three weeks of initial infection. Because of the expense and expert analytical skills required, they are not often used for individual HIV testing.
