Given its status as being a widespread disease and major concern for medical foundations throughout 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 focus on improvements across several HIV testing metrics: speed, reliability, accuracy, and applicability have all increased as new generations of ชุดตรวจ HIV ร้านขายยา emerge.
What does this relate to you? Plenty! Doctors and healthcare professionals everywhere increasingly encourage routine HIV testing as a means of ensuring personal health and addressing the spread of HIV. Remember, HIV can survive in the host without obvious symptoms for long amounts of time. Seeking this in a trusted facility not merely protects your future health, but also that of your loved ones and intimate partners.
No matter which test you take, it’s mandatory to follow up a positive result with alternative tests-this drastically reduces the possibility of a fluke in the test. You should also know that lots of the home HIV testing kits on the market haven’t received FDA approval and are rife with inaccuracy. With that in mind, below are a few particulars on various professional HIV testing options that are available to you:
Antibody Tests – These are the basic most frequent HIV testing procedures for routine screening. They make use of the fact that your body naturally produces anti-infection proteins called antibodies in reaction to HIV infection. This process detects antibodies 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 some important considerations with antibody tests. Because the body takes time to build up antibodies, there exists a “window period” during which HIV-positive individuals may receive false negative results since they tested too early. Because of this, this technique of HIV tests are recommended three months after potential exposure. If the HIV-positive mother includes a child, their antibodies will likely be passed on and retained in the baby’s body for as much as eighteen months; other tests are recommended in this case. Similarly, those who have participated in HIV vaccine trials should take multiple tests to lower the possibility of false results.
Rapid HIV Tests – These operate on the same principles as antibody tests with much faster turnaround. They take less than an hour and often require no follow-up visit; all 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 suited to urgent medical situations or places that clients are unlikely to go back to check on the results.
Antigen Tests – These tests seek substances through the HIV virus itself, called antigens. Specifically, they seek the P24 protein produced in early stages of HIV infection. This number 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 enhance accuracy while reducing the “window period.” Called fourth-generation tests, these new trends in this particular 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 your genetic material in 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 also effective within several weeks of initial infection. Because of the expense and expert analytical skills required, they are certainly not often employed for individual HIV testing.
