POSITIVE RESULT: Two colored lines appear. A colored line should always appear in the Control (C) region and another line should be in the Test (T) region. A positive result indicates detection of SARS-CoV-2 antigens in the sample.

Μπορείτε να λάβετε βεβαίωση αρνητικού αποτελέσματος σε διαγνωστικό ελέγχο κορωνοϊού COVID-19. Η βεβαίωση μπορεί να εκδοθεί για διαγνωστικούς ελέγχους (PCR ή Rapid Test) που κάνατε μέχρι και ένα μήνα ...
COVID-19 rapid antigen tests or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection . They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing , and give users a result within 5–30 minutes.
12 maj 2020 · Interpreting the result of a test for covid-19 depends on two things: the accuracy of the test, and the pre-test probability or estimated risk of disease before testing. A positive RT-PCR test for covid-19 test has more weight than a negative test because of the test’s high specificity but moderate sensitivity.
22 cze 2021 · This practice pointer considers how to interpret and communicate results from LFD tests based on our current understanding of the tests’ performance. Lateral flow devices can detect the presence of a target substance in a liquid, typically in a single use disposable …
21 kwi 2021 · Rapid antigen test (RAT) kits have emerged as an important alternative tool to aid in the clinical diagnosis of COVID-19. RAT is based on immunochromatography, which employs antibodies spotted onto nitrocellulose membranes that interact with specific antigens from the patient sample.
SARS-CoV-2 reverse transcriptase–polymerase chain reaction (RT-PCR) testing is highly sensitive (99%) but less specific (approximately 95%) for contagious COVID-19 and may be positive for ≥90 days after infection. Viral antigen tests have lower analytic sensitivity than RT-PCR but are more specific for contagious disease
