Nevertheless, there are some works that have integrated an IAC on their diagnostic assays as shown in Table 1. Incorporating an IAC into POC NAATs can present challenges such as requirements of more complex assay design and higher volume of samples to run the control, which subsequently leads to additional user step. While many emerging publications on NAATs for SARS-CoV-2 show remarkable analytical sensitivity in the laboratory setting, assessing clinical accuracy with IAC is often overlooked.

The inclusion of an IAC in POC diagnostics can help to reduce the risk of false-negative results, which can have serious implications for the management of infectious diseases due to delayed or inadequate treatment, potentially resulting in disease transmission, increased morbidity, and mortality. IACs are also crucial in POC diagnostics to ensure accurate and reliable detection, particularly when performed at locations with limited access to laboratory facilities. An IAC, sometimes referred to as a sample adequacy control, can contain a synthetic target sequence of different length, a non-target sequence, or a housekeeping gene of human cells to ensure sample is adequately collected and prepared. In the lab, an IAC is commonly run in parallel with NAATs in order to rule out a false-negative result and to qualify the sample collection process as well as the integrity of the amplification enzymes and conditions in a presence of complex matrix. Īccording to the US FDA guidelines for in vitro diagnostic devices, internal analytical controls (IACs) are among the essential controls mandated for the industry. Without the same level of quality control and assurance as laboratory-based tests, sample quality and the way it is collected and handled can lead to challenges with accuracy, reliability, and reproducibility. However, this has also given rise to user concerns regarding the accuracy and effectiveness of these tests and has raised questions about the future of at-home diagnostics for other infectious diseases. Due to the COVID-19 pandemic, there has been a rapid increase in the development and availability of point-of-care (POC) and home-based nucleic acid amplification tests (NAATs) for respiratory infections.
