3. Adding COVID-19 and other virus testing to your laboratory
In the previous chapter, the most common testing methodologies for COVID-19 and other coronaviruses was discussed in detail. The common thread among them all was the use of real-time reverse-transcription polymerase chain reaction (rRT-PCR) assays for testing.
"The PCR technique has been found to be useful in pharmaceutical and biotechnology research activities as well as microbial quality testing. The technique is also applied in genetic engineering. It is used to identify genes related to certain phenotypes including genetic disorders. Regular testing of the microbial load of raw materials and finished products is an important process in the pharmaceutical & biotechnology industry. Sophisticated analytical methods such as polymerase chain reaction (PCR) have been widely applied for quality control analysis in the pharmaceutical sector."
"Continuous technology advancements are making it more efficient and user-friendly, but the high cost of the instruments, servicing contracts, and reagents pose major challenges for the market, especially to the price-sensitive academics. Currently, the market players are involved in enhancing the capabilities of the PCR systems, and increasing its specificity and sensitivity."
