Development of a Bioaerosol Sampling Method for Airborne Pathogen Detection with Focus on SARS-CoV-2

Table 3

Results obtained after PCR analysis of 10 air samples collected at the apartment in Brussels, Belgium.

Sampling day	Sample ID	Presence of SARS-CoV-2	Ct value
1	House # 01	Non-negative (LV)	35.01
	House # 02	Non-negative (LV)^†	39.77^†
	House # 03	Non-negative (LV)	37.69
	House # 04	Non-negative (LV)	37.58
	House # 05	Non-negative (LV)	38.20
2	House # 06	Negative	—
	House # 07	Negative	—
	House # 08	Negative	—
	House # 09	Negative	—
	House # 10	Negative	—

For SARS-CoV-2, samples with are reported as positive and with as “limit value” (LV). For the other pathogens, the cut-off is . ^†For SARS-CoV-2, was calculated as limit of blank (LoB). Although not strictly applicable as a cut-off, samples with have increased probability of being false positives. LoBs were not derived for other pathogens.
