The investigators performed throat cultures and rapid antigen tests
and used clinical information to derive a clinical prediction score in each of 787 patients, aged 3-69 years, who presented with acute sore throat.
Molecular methodologies deliver the best opportunity to detect this influenza variant by nucleic acid sequence detection, whereas the CDC has shown that several rapid antigen tests
fail to detect this variant influenza virus.
On the other hand, commercially available rapid antigen tests
such as Directigen Flu A+B (Becton Dickinson, Sparks, NJ, USA) or Binax NOW (Binax Inc.
The overall sensitivity of rapid antigen tests
for group A streptococcus has declined in recent years.
Comparison of a rapid antigen test
with nucleic acid testing during cocirculation of pandemic influenza A/H1N1 2009 and seasonal influenza A/H3N2.
The approval of our PDL CWD Rapid Antigen Test
is a significant milestone for our company and represents the first of many approvals we expect to receive during the coming year," said David S.
4) In the pediatric study by Geiseker, et al, a single rapid antigen test
had a sensitivity of 87.
If such rapid antigen tests
are used as a first-line diagnostic modality, it is recommended that negative results be confirmed by a more sensitive method such as culture or polymerase chain reaction.
The D3 FastPoint L-DFA RSV/MPV Identification Kit will allow laboratories to identify respiratory syncytial virus and metapneumovirus infections in the same timeframe as currently available point-of-care rapid antigen tests
, which generally do not include MPV testing options.
Lack of sensitivity of rapid antigen tests
for the diagnosis of respiratory syncytial virus infections in adults.
The D3 FastPoint L-DFA Influenza A/ Influenza B Virus Identification Kit will allow laboratories to identify influenza A virus and influenza B virus infections in the same timeframe as currently available point-of-care rapid antigen tests
2) In this study, which was carried out during the 2009 Influenza A/H1N1 (swine flu) outbreak in New York, 1,382 patient samples were initially tested with a variety of methods including rapid antigen tests
, direct immunofluorescence, and rapid virus culture.
