INTRODUCTION Innovative strategies, such as HIV self-testing (HIVST), could increase HIV testing rates and diagnosis. Evidence to inform the design of an HIVST intervention in the UK is scarce with very little European data on this topic. This study aims to understand values and preferences for HIVST interventions targeting MSM in the UK. We explore the acceptability of HIVST among MSM in the c...

BACKGROUND The aim of this study was to determine whether postal testing kits (PTKs) or patient-delivered partner therapy (PDPT) for partners of women with Chlamydia trachomatis reduce re-infection rates in women, compared with partner notification by patient referral. METHODS Three hundred and thirty women testing positive for chlamydia, at clinics for genitourinary medicine, family planning...

Federal workplace drug testing was initiated during the late 1980s. Since then, numerous methods have been employed to subvert these drug tests, adulteration of urine samples being the most common. A wide variety of adulterants has been reported to date along with suitable methods of their detection. Recently, websites have claimed that zinc sulfate can be an effective adulterant to bypass drug...

Diagnosis of human immunodeficiency virus (HIV) infection is important for patient management and prevention of new infections. The number of test kits available for the detection of HIV antibodies is unprecedented. In order to identify appropriate test kits, we evaluated a variety of commercial kits manufactured abroad as well as in India. The plasma and serum specimens (n=264) were collected ...

Cybercrime attack tools (i.e. Exploit Kits) are reportedly responsible for the majority of attacks affecting home users. Exploit kits are traded in the black markets at different prices and advertising different capabilities and functionalities. In this paper we present our experimental approach in testing 10 exploit kits leaked from the markets that we deployed in an isolated environment, our ...

OBJECTIVE Seven recombinant viral capsid antigen-IgA (VCA-IgA) ELISA kits are widely used in China, but their diagnostic effects have not been evaluated. In this study, we evaluated whether the diagnostic effects of these kits are similar to those of the standard kit (EUROIMMUN, Lübeck, Germany). METHODS A diagnostic case-control trial was conducted with 200 cases of nasopharyngeal carcinoma ...

OBJECTIVE There are various methods for anti-dsDNA detection. Crithidia luciliae indirect immunofluorescence test (CLIFT) and enzyme immunoassay (EIA) are the most commonly used at present. A number of CLIFT and EIA kits are commercially available. The objective of the present study was to evaluate the diagnostic performance of three commercial CLIFT kits, two commercial EIA kits, and their com...
