  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. Goniometer - Wikipedia

    en.wikipedia.org/wiki/Goniometer

    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.

  4. Viral culture - Wikipedia

    en.wikipedia.org/wiki/Viral_culture

    Viral culture is a laboratory technique [1] in which samples of a virus are placed to different cell lines which the virus being tested for its ability to infect. If the cells show changes, known as cytopathic effects, then the culture is positive.

    A COVID-19 Rapid Antigen test(top) with a Covid-19 Rapid Antigen and a Influenza A&B Rapid Antigen Test(bottom) A rapid antigen test (RAT), sometimes called a rapid antigen detection test (RADT), antigen rapid test (ART), or loosely just a rapid test, is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an antigen.

  6. Nucleic acid test - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_test

    Rotavirus. A nucleic acid test (NAT) is a technique used to detect a particular nucleic acid sequence and thus usually to detect and identify a particular species or subspecies of organism, often a virus or bacterium that acts as a pathogen in blood, tissue, urine, etc. NATs differ from other tests in that they detect genetic materials (RNA or DNA) rather than antigens or antibodies.

  7. Virus quantification - Wikipedia

    en.wikipedia.org/wiki/Virus_quantification

    Virus quantification is counting or calculating the number of virus particles (virions) in a sample to determine the virus concentration. It is used in both research and development (R&D) in academic and commercial laboratories as well as in production situations where the quantity of virus at various steps is an important variable that must be monitored.
