25 sie 2023 · Test PCR jest badaniem molekularnym, które stanowi podstawę diagnostyki zakażeń wirusem SARS-CoV-2. Umożliwia wykrycie materiału genetycznego koronawirusa po pobraniu wymazu z gardła lub nosogardzieli. Tego rodzaju test wykorzystuje się też do rozpoznania innych zakażeń wirusowych i bakteryjnych.
24 kwi 2020 · W przypadku diagnostyki COVID-19 stosuje się specyficzną odmianę metody PCR, czyli PCR z odwrotną transkrypcją w czasie rzeczywistym (w skrócie RT-PCR).
18 sty 2022 · COVID-19 PCR tests use primers that match a segment of the virus’s genetic material. This allows many copies of that material to be made, which can be used to detect whether or not the virus is present. A positive COVID-19 PCR test means that SARS-CoV-2 is present.
29 sie 2024 · Nucleic acid amplification tests (NAATs) are highly sensitive and highly specific tests that detect one or more viral ribonucleic acid (RNA) genes. PCR tests are the most common type of NAAT used for COVID-19 testing. Viral RNA may stay in a person's body for up to 90 days after they test positive.
9 lis 2021 · Two major types of tests are used to diagnose infection with SARS-CoV-2: molecular tests – better known as PCR tests – and antigen tests. Each detects a different part of the virus, and how it works influences the test’s speed and relative accuracy.
COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2, the virus that cases COVID-19 and is responsible for the COVID-19 pandemic. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection.
24 sie 2021 · The polymerase chain reaction (PCR) test for COVID-19 is a molecular test that analyzes your upper respiratory specimen, looking for genetic material (ribonucleic acid or RNA) of SARS-CoV-2, the virus that causes COVID-19.
