Given its status as being a widespread disease and major concern for medical foundations across the globe, it should come as not surprising that HIV treatment and detection have come a long way since their inception. Over time, new methodologies have emerged to highlight improvements across numerous HIV testing metrics: speed, reliability, accuracy, and applicability have all increased as new generations of ชุดตรวจ HIV ร้านขายยา emerge.
What does this pertain to you? Plenty! Doctors and medical professionals everywhere increasingly encourage routine HIV testing as a way of ensuring personal health and addressing the spread of HIV. Remember, HIV can survive in the host without obvious symptoms for long time periods. Seeking this at a trusted facility not merely protects your future health, but also those of your family and intimate partners.
No matter what test you are taking, it’s mandatory to follow along with up a good result with alternative tests-this drastically reduces the possibility of a fluke inside the test. You should also know that most of the home HIV testing kits on the market haven’t received FDA approval and therefore are rife with inaccuracy. With that in mind, here are a few information on various professional HIV testing options that are available to you:
Antibody Tests – These are the basic most common HIV testing procedures for routine screening. They take advantage of the proven fact that your body naturally produces anti-infection proteins called antibodies in reaction to HIV infection. This process detects antibodies coming from a blood, saliva, or urine sample. Usually an enzyme-linked immunosorbent assay (ELISA) will be the preferred antibody test due to the high sensitivity.
There are a few important considerations with antibody tests. As the body needs time to develop antibodies, you will find a “window period” during which HIV-positive individuals may receive false negative results since they tested too soon. Because of this, this process of HIV testing is recommended three months after potential exposure. If the HIV-positive mother features a child, their antibodies will likely be transferred and retained inside the baby’s body for up to 18 months; other tests are recommended in this case. Similarly, individuals who have took part in HIV vaccine trials should take multiple tests to reduce the risk of false results.
Rapid HIV Tests – These operate on the same principles as antibody tests with much faster turnaround. They take lower than an hour and often require no follow-up visit; all of the analysis is carried out on-site by medical professionals. These are easier for medical staff to conduct and minimally invasive for that patient. These are generally fitted to urgent medical situations or locations where customers are unlikely to go back to check on their own results.
Antigen Tests – These tests seek substances from your HIV virus itself, called antigens. Specifically, they seek the P24 protein produced in the early stages of HIV infection. This selection 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 boost accuracy while lowering the “window period.” Called fourth-generation tests, these new trends within this testing will show on top of dveaos frequency as medical technology will continue to advance.
PCR Tests – Polymerase Chain Reaction (PCR) tests also detect HIV infection early by testing for that genetic material of the virus. Also called the viral load test or nucleic acid amplification testing (NAAT), PCR HIV testing is suited for screening blood supplies or newborns and is effective within several weeks of initial infection. As a result of expense and expert analytical skills required, they are not often employed for individual HIV testing.
