Versi•SAL®
Versi•SAL® is a unique fluid saliva collection device that incorporates a proprietary "fork-shaped" pad for immediate split-sample saliva (and other fluid) collection. Versi•SAL® works by placing the device pad under the tongue and collecting saliva (oral fluid) until a novel sample sufficiency indicator (b, above) is triggered. The collector is then pushed down into the compression tube (c) supplied until the Versi•SAL® device snaps into place by means of a lock (g) and key (f) type mechanism. This forces the saliva specimen through two separate porous filter outlets (d) into two separate, mutually distinct, graduated Eppendorf-style tubes (e). The primary sample obtained may then be tested immediately in point-of-care applications or sent to a laboratory for subsequent testing. The secondary sample is used for further testing or confirmatory purposes.
Instructions for Use
1) Take the collection device (a) and place dual pads UNDER the tongue 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 adequate volume of saliva specimen has been collected.
3) Push Versi•SAL® device (a) down into the compression tube (c) and push until the device locks into place by means of a lock (g) and key (f) mechanism (as shown in figure 3).
4) This shows the Versi•SAL® device locked in place. Saliva will flow from the sample pads, through the dual particulate filter outlets (d) and into each of the two Eppendorf-style tubes (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 samples 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.
