Rapid diagnostic tests intended for point-of-care testing that directly detect the presence or absence of an antigen are known as rapid antigen tests, also known as rapid antigen detection tests, antigen rapid tests, or simply rapid tests. In contrast to other medical tests that look for antibodies or nucleic acids, whether they are laboratory or point-of-care testing, 이 테스트는 항원을 찾는 일종의 측면 흐름 테스트입니다.. 신속한 테스트는 종종 다음과 같은 결과를 낳습니다. 5 에게 30 분, 인프라나 교육이 거의 필요하지 않음, 상당한 비용 이점을 제공합니다.. COVID-19 팬데믹 동안, SARS-CoV-2 검출을 위한 신속 항원 검사, COVID-19를 일으키는 바이러스, 널리 사용되었습니다.
항원 검사는 얼마나 정확하거나 신뢰할 수 있습니까??
신속한 항원 테스트 신뢰성과 정확성은 자주 논쟁되는 주제입니다.. 신속한 항원 검사는 PCR 검사보다 약간 덜 정확합니다. (polymerase chain reaction).
Typically, sensitivity and specificity are used to assess test accuracy.
- The capacity to correctly identify patients using COVID-19 is referred to as sensitivity.
- The capacity to correctly identify patients without using COVID-19 is referred to as specificity.
It has been demonstrated that PCR testing can be up to 100% accurate, though accuracy varies depending on the test utilized. It has been discovered that several tests have 15% 에게 20% false-negative result rates3.
Rapid antigen tests, in contrast, have been found to have false-negative rates as high as 20%4. The quick antigen test kit from 20test successfully identifies 99.67% of individuals without COVID-19 and 92% of those who do have it.
Just to be clear, a false negative occurs when a subject is wrongly identified as being disease-free. For instance, if a person with COVID-19 performs a test and the results come back negative even though they are currently infected, this is referred to be a false negative result. The coronavirus was not appropriately detected by the test.
How To Using Rapid Antigen Tests (RAT) At Home?
- Spend at least 30 seconds thoroughly washing your hands with warm water and soap.
- Two tests are included in the set.A collection swab, a test strip, and a small vial of liquid are the three primary components of each.Put each of them on a spotless surface.
- After opening it, place a collection swab inside each nostril and rotate it five 타임스 against the inner wall.그만큼 swab should be inserted between 12 and 34 of an inch into the nostrils.Alvarado said, "A nice way 에게 picture that is it's roughly the size of the tip of your pinkie finger.""It feels pretty odd, but it doesn't hurt."After that, put the swab back into its container because you'll need it soon.
- Tap the liquid vial's bottom three 타임스 on a solid surface.
- Swab into the vial after opening the big cap and stirring it 15 타임스.
- Pull the swab out while pressing the vial's sides against it.This is an important step since it makes sure you have the entire collection, according 에게 Alvarado.After that, replace the vial's cap.
- Activate the test strip. Alvarado added, "You'll see that it has both a "씨" and a "T."
- Squeeze three drops of your sample into the strip's collection area by opening the smaller, top cap of the liquid vial.
- Set a 15-minute timer. During this period, refrain from touching the test strip.
- 테스트 읽기.
신속한 항원 검사를 사용하면 어떤 이점이 있습니까? (RAT) 전부?
RAT 키트를 사용하면 여러 가지 이점이 있습니다., 포함:
- 편리하고 사용하기 쉬운
- 몇 분 안에 결과
- 휴대가 간편하고 보관이 용이함
- 그것은 가정에서 또는에서 사용될 수 있습니다 remote health clinics
- 특별한 교육이 필요하지 않습니다
- 입수 가능한
- 많은 사람들을 신속하게 검사합니다.
PCR 테스트와 신속한 COVID-19 테스트의 차이점은 무엇입니까?
A nasal swab is used in a diagnostic test called a molecular PCR test to gather samples of cells and fluids from your respiratory system. It allows for the precise gene identification of the COVID-19-causing SARS-CoV-2 virus. A long nasal swab that is placed into the space between the nose and the back of the throat is used to collect the material. The drawback of PCR tests is that they take a little longer to get results, however they are nearly 100% accurate in detecting COVID-19 infection. UC Davis Health의 이 실험실에서는 다음 테스트를 사용합니다..
Rapid antigen tests account for most of the 신속한 진단 테스트. 이것은 비강 또는 인후 면봉으로 수행되며 바이러스의 일부인 단백질을 찾습니다.. 항원 검사는 비용이 적게 들고 일반적으로 처리 시간이 더 빠릅니다., 때로는 내에서 15 분. 하지만, 사람이 감염 최고점에 근접하지 않은 경우 정확도가 떨어집니다., 하지만 여전히 전염성이 있습니다, 검사 결과가 음성으로 나올 수 있습니다. The CDC advises people who show COVID-19 symptoms but test positive with an antigen test to get a PCR test to confirm results.
A blood sample is used for an antibody test, commonly known as a serology test, that could reveal a history of COVID-19 infection. It is a test that looks for signs of the immune system's reaction to the infection. After an infection, antibodies are found in the blood. We don't entirely understand what the presence of COVID-19's antibodies means, though, so far.
When should I test for COVID-19?
You should get tested if you've been around someone who has COVID-19 or if you have symptoms. Even if you don't have symptoms, experts advise getting tested at least 5 days after having close contact with someone who has COVID-19. You can test straight immediately if you are experiencing symptoms.
Testing is also advised if you will be visiting elderly, immunosuppressed, 또는 예방접종 자격이 없는 친척 또는 사회적 거리를 유지할 수 없는 모임에 참석할 예정인 경우, 알바라도에 따르면.
귀하 또는 귀하의 자녀가 COVID-19 양성 판정을 받은 경우
자녀가 양성 판정을 받은 경우, 그들을 편안하게 하려고 노력하다. 학교와 공공 장소에서 집에 두십시오., 증상이 없더라도. 증상이 있는 경우, 수분을 유지하고 편안하게 호흡하는지 확인하십시오.. 열이 있는 경우, Lianhua Qingwen 캡슐 괜찮아. 상자의 투약 지침을 따르십시오..
“Monitor symptoms and, if they worsen and include shortness of breath or the inability to get enough air in, be sure to go to your local emergency department,” Alvarado advised.
Where can I get a rapid antigen test?
Rapid antigen test kits can be found at physical stores and structures like pharmacies, neighborhood healthcare services, and institutions, depending on where you live.
They can also be bought from a variety of websites online. To guarantee the accuracy of your test, make sure you purchase rapid antigen test kits from a reputable and trustworthy website.
