VPSS: Viral PCR Sample Solution inc. ordering

Please note: After the 1st Jan 2018 VPSS samples received containing the swab will be discarded and NOT processed. Please cascade this information to your fellow colleagues who use this service.

Please note: do NOT wet swabs with liquid in virus PCR (VPSS) tube before taking samples. Be careful handling the Virus PCR solution as VPSS is mildly caustic. If you splash the solution on your hands, skin or eyes, please rinse with copious amounts of water.

Flocked swabs (which have improved sample collection and release in to VPSS) should be used wherever possible (to offer the greatest sensitivity), in conjunction with Viral PCR Sample Solution, however any swab maybe used with VPSS.

The quality of the sampling when taking a swab is vital to the detection of any pathogen present.  

After the swab is taken, the swab should be expressed on the side of the VPSS vial, releasing any pathogen present into the fluid. The swab should then be discarded. The cap replaced tightly prior to the vial being sent to the laboratory. The pathogen will be inactivated (rendered uninfectious) and the genome preserved for testing within the VPSS fluid.

Swab types for addition to VPSS include (but are not limited to) nose and throat (nose and throat swabs should be taken separately and expressed into the SAME VPSS vial), genital ulcer/vesicle, eye, vesicle, ulcer, lesion, mouth, pharyngeal and rectal swabs.

Swab samples NOT to be used with VPSS are vulvovaginal, rectal and pharyngeal swabs for Chlamydia trachomatis and Neisseria gonorrhoeae PCR. Please use the Abbott multi-collect specimen collection kit for these samples. Genital swabs received in VPSS will automatically receive PCR testing for herpes simplex virus-1 (HSV-1), herpes simplex virus-2 (HSV-2) and Treponema pallidum (Syphilis)

When Viral PCR Sample Solution (VPSS)is not available, swabs can be cut off and sent dry in a sterile container. This should be avoided whenever possible as the virus remains infectious and sensitivity is reduced. VPSS inactivates and preserves the pathogen genome for PCR testing.
