What is the Difference between PCR and Serological Test?

Nucleic Acid Test

Highly accurate, demanding, and long time-consuming, suitable as the first line of defence; capable of discovering infected people in the window period;

There are higher requirements for the detection platform and personnel. If the test result of the suspected patient is negative, the infection cannot be ruled out, and a follow-up test is required.

Serological Test

Simple, fast, generally accurate, suitable as an auxiliary; specimens are easy to obtain, easy to operate, and short time-consuming; however, it takes time to produce antibodies after the antigen enters the body, with a window period.

Nucleic Acid Detection Reagents FAQs

  • Q

    How long does the nucleic acid swab test take to result by Genrui products ?

    A :

    Nucleic acid swab testing generally produces results within 2 hours, because sampling, specimen submission, specimen testing, and verification of specimen results require a certain amount of time, so designated hospitals can get the test report within 2 hours. Nucleic acid detection is mainly through throat swab sampling.

  • Q

    What is a viral nucleic acids test?

    A :

    A viral test not only detects antigens (generally pathogen surface proteins, some are internal nuclear proteins) but also nucleic acids. During the outbreak of this pandemic, doing a viral nucleic acids test by PCR technology has become a major contributor to the detection of pathogens.
