These technologies generally can be grouped into three approaches: polymerase chain reaction (PCR), hybridization, and next-generation sequencing (NGS). [22] Currently, a lot of PCR and hybridization assays have been approved by FDA as in vitro diagnostics. [47] NGS assays, however, are still at an early stage in clinical diagnostics. [48]
Moreover, for pathogen sequencing the use of controls is of fundamental importance ensuring mNGS assay quality and stability over time; PhiX is used as sequencing control, then the other controls include the positive control, an additional internal control (e.g., spiked DNA or other known pathogen) and a negative control (usually water sample). [2]
Illumina claimed that Oxford Nanopore infringed its patents on the use of a biological nanopore, Mycobacterium smegmatis porinA (MspA), for sequencing systems. [64] [65] In August 2016 the parties settled their lawsuit. [66] In February 2020, Illumina filed a patent infringement suit against BGI relating to its "CoolMPS" sequencing products. [67]
Fluorescein diacetate (FDA) hydrolysis assays can be used to measure the enzyme activity of microbes in a sample. A bright yellow-green glow is produced and is strongest when enzymatic activity is greatest. This can be quantified using a spectrofluorometer or a spectrophotometer.
Direct-to-consumer tests are regulated as medical devices, although they are not necessarily reviewed by the FDA. [8] 23andMe direct-to-consumer genetic tests were originally offered as LDTs, but the FDA challenged that and forced the company to submit the test for approval as a class II medical device. [9] [10]
The iHealth COVID-19 test is easy to use and accurate, according to more than 7,600 shoppers.
