Respiratory viral infection i.e., SARS-CoV-2 infection is expected to activate TLR2, TLR3, TLR4 and TLR7 responses and this is likely to modulate commensal microbiota populations. According to a study from March, at-home rapid tests are "not inferior among individuals infected with the SARS-CoV-2 Omicron variant as compared to the Delta variant.". So theoretically, there is a possibility that if you are cleaning everything out and diluting things, it may impact a COVID-19 test..

Most patients have detectable IgG antibodies by day 14 following symptom onset, and the likelihood of detection increases over time. Over the following months, it quickly spread across the continent and, in short order, the globe, making an impact that hasn't been seen in generations. Testing a swab from the oropharynx or nose is also likely to reduce sensitivity.1,2 Other sample types such as saliva or blood likely result in even lower sensitivity.3 For patients with frank pneumonia, on the other hand, specimens such as bronchoalveolar lavage collected from the lower respiratory tract may have sensitivity equal to or better than an NP swab, although collection of these types of samples increases the biosafety risk to healthcare workers.4. Different assays use antigens from different parts of SARS-CoV-2, and some combine IgM and IgG, and so different levels of cross-reactivity with other coronavirus antibodies are possible.

New research indicates that a gargle lavage (mouthwash) test is just as accurate as a swab assessment and a much simpler process to boot.
