  2. Laboratory diagnosis of viral infections - Wikipedia

    en.wikipedia.org/wiki/Laboratory_diagnosis_of...

    Detection of viral RNA and DNA genomes can be performed using polymerase chain reaction. This technique makes many copies of the virus genome using virus-specific probes. Variations of PCR such as nested reverse transcriptase PCR and real time PCR can also be used to determine viral loads in patient serum.

  3. Viral culture - Wikipedia

    This greatly reduces the time to detection for slow growing viruses such as cytomegalovirus, for which the method was developed. [3] In addition, the centrifugation step in shell vial culture enhances the sensitivity of this method because after centrifugation, the viral particles of the sample are in close proximity to the cells.

    The bevel protractor is used to establish and test angles to very close tolerances. It reads to 5 arcminutes (5′ or ⁠ 1 / 12 ⁠ °) and can measure angles from 0° to 450°. The bevel protractor consists of a beam, a graduated dial, and a blade which is connected to a swivel plate (with Vernier scale) by a thumb nut and clamp.

    On Oct. 7, the FDA authorized the first over-the-counter home flu and COVID-19 combination test outside of emergency use authorization, which can detect SARS-CoV-2 (the virus that causes COVID-19 ...

  7. Human coronavirus NL63 - Wikipedia

    en.wikipedia.org/wiki/Human_Coronavirus_NL63

    It is difficult to distinguish between symptoms caused by infection of the HCoV-NL63 virus and those caused by other common human viruses, making diagnosis and detection complex. Reverse transcription polymerase chain reaction of samples collected through nasopharyngeal swab is the most commonly used method for detection of the virus. [ 10 ]
