"False positive results will happen in a fraction of a per cent of occasions, but false negatives (a negative result when in fact you do have Covid-19) are more common. 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. This is known . This has never been more true than it is now, given the attention on COVID-19 testing and its role in helping to halt the spread of COVID-19. NP swab samples are technically challenging to obtain, and a suboptimal collection may reduce test sensitivity and increase the likelihood of obtaining a false-negative result in a patient with the virus. Wearing a face mask should be high on the list. Although it might be tempting to stock up on home COVID-19 tests, keep in mind that the kits expire within several months to a year. 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. Test manufacturers and laboratories often report the analytic sensitivity and specificity of a test, which are based on the analysis of a set of known positive and negative samples.
