Researchers revealed that when it comes to screening for sexually transmitted infections (STIs), female commercial sex workers (CSW) prefer self-collection of samples to traditional tests.
The simple and convenient screening method used by the researchers at the University of Westminster didn't require the sex workers to attend clinics.
The women were given tampons that they could use to collect their own samples, and post them to a laboratory.
The results also indicated that the women in the study found self-collection of samples very easy and the testing methods used in the study proved to be more accurate than traditional tests.
Lead author of the study, Dr. Patrick Kimmitt, pointed out that despite their risk of exposure to STIs, female CSW were reluctant to attend clinics for regular screening for such infections.
That might due to unsuitability of opening times, fear of stigma or the false concern of the possibility of being reported to the police.
"Point of care testing" delivered at their workplace is more attractive to this patient group.
The study involved 65 CSW, all of whom were asked to complete a questionnaire in which they indicated their preferences for screening and ease of use of sample collection.
The samples were processed in the laboratory using a method called PCR (Polymerase Chain Reaction) which rapidly detects a unique DNA sequence in three of the micro-organisms that cause STIs, gonorrhoea, Chlamydia and Trichomonas.
