sample for any additional tests. If NP swabs are used, swab material should becalcium alginate,Dacron, or rayon because cotton will inhibit the growth ofB. pertussis.Specific transport media should be used for NP specimens, including 1% acid-hydrolyzed casein or Amies medium with charcoal. ...
(4.8%) with VCA-IgA titer ≥ 1:5 were defined as high-risk NPC group and further followed up for NPC occurrence. A non-invasive nasopharyngeal swab was used in 905 high-risk group, and 89% was detected as EBV DNA positive, while eight subjects with EBV DNA load higher than the ...
(BD Biosciences) with 8-μm pores present in the insert of a 24-well culture plate. FBS was added to the lower chamber as a chemo-attractant. After 18 h, the non-invading cells were gently removed with a cotton swab. Invasive cells located on the lower side of the chamber were ...
After 24 h, the cells in the insert were gently removed using a cotton swab. Cells on the reverse side of insert were fixed and stained with hematoxylin and eosin. The number of invading cells was counted in four representative fields per membrane by using light microscopy at × 40 ...
However, the collection of a swab sample is invasive, and during the time of the pandemic, there have been considerable shortages in swab supplies. Exploring the use of alternative sample types that are both easy to collect and more comfortable from a sampling perspective4, 5, 6 is desirable...
PCR test nasal swab uses a nasal swab culture to detect the genetic material of the pathogen, and it is the most reliable and accurate test for detecting active infection. PCR tests typically take hours to perform, but some types are faster. On the other hand, an antigen test detects bits...
