Versi•SAL®
Versi•SAL® is a unique fluid collection device that incorporates a proprietary interchangeable absorbent pad for immediate saliva (and other fluid) collection. Versi•SAL®1 works by placing the device pad under the tongue and collecting saliva (oral fluid) until a novel sample sufficiency indicator (b, above) is triggered [1-2 minutes]. The collector is then pushed down into the compression tube (c) supplied until the Versi•SAL®1 pad is significantly compressed to leak saliva. The saliva specimen is forced through an outlet (d) into a graduated Eppendorf-style tube (e). The sample obtained may then be tested immediately in point-of-care applications or sent to a laboratory for subsequent testing.
Instructions for Use
1) Take the collection device (a) and place the absorbent pad UNDER the tongue and collect saliva until the sample sufficiency indicator (b) is triggered. At this point the blue-coloured line disappears indicating adequate volume of saliva has been collected for subsequent analysis, testing or storage for later analysis.
2) Left frame above shows the sample sufficiency indicator BEFORE sufficient fluid (saliva) has been collected. Right frame above shows the sample sufficiency indicator AFTER an adequate volume of saliva specimen has been collected.
3) Push Versi•SAL® 1 device (a) down into the compression tube (c) and push until the device can be pushed no further down ( the pad will appear totally compressed and saliva will begin to flow into the collection tube.
4) This shows the Versi•SAL® 1 device with fully compressed absorbent pad material. Saliva will be flowing from the sample pad, through the dual particulate filter outlet (d) and into the Eppendorf-style tube (e).
5) Remove each of the Eppendorf-style tubes (e) from the dual particulate filter outlets (d) and close caps. NOTE: The volume of saliva may not necessarily be the same in each of the Eppendorf-style tubes (e).
6) Use the saliva sample collected for immediate (point-of-care testing) applications, send to a qualified laboratory for additional testing or store in a freezer at -20° or -70° Celsius for later analysis.
