Procedures for quality assurance of the test are still in development [ 17] and the accuracy of the test when adopted by non-expert groups needs to be confirmed [ 18].
For quality assurance of HIV testing, additional HIV testing was conducted off-site.
The respondents were encouraged to submit information on their needs and capacity in relation to DNA preparation, sequencing, and analysis (e.g. variant detection and clustering) enabling the organisers to take this information into consideration when creating the PT and in the work towards standardised testing and quality assurance of these tests.
Most common problems encountered in the studies were that the researchers did not present validity (n=28) and reliability (n=24) assurance of the tests and the results.
In recent years, rapid point-of-care tests have allowed greater access to syphilis screening, especially in rural or remote areas, but the lack of quality assurance of rapid testing has been a concern.
SRM 2585 (Organic Contaminants in House Dust; National Institute of Standards and Technology, Gaithersburg, MD) was used for quality assurance, to test performance of the dust extraction method for PBDEs.
Bovine serum (Invitrogen, Carlsbad, CA) and deionized water were both used as laboratory blanks, and SRM 1958 [Fortified Human Serum; NIST National Institute of Standards and Technologyy), Gaithersburg, MD] was used for quality assurance to test performance of the extraction method for PBDEs and HBCD.
