POST 00598E : SHAKE TEST Follow-up on POSTS 00571E, 00574E, 00575E, 00579E, 00590E and 00593E 17 August 2003 _____________________________________ Kartoglu (mailto:[log in to unmask]) proposes some comments relative to the shake test and shares a slideshow to help its interpretation further. Please note that a timer is included so you don't need to change pictures yourself. It will do automatically....at least they're supposed to. _____________________________________ 1. I agree with Sam Okinor's observations and suggestions. But would like to remind that we have to be extremely careful when it comes to lowest level. At this level, health facilities usually have only one refrigerator and when something goes wrong it is all vaccines that are affected. It is very unlikely that one could find (for sure) an alternative vaccine to use. 2. Thanks to Ms. Danile Kohl for sharing this beautiful presentation with us. Here, I would like to underline that the shake test is not a STATIC test that you shake the vials and come back in say 30 minutes to see the difference. It is a DYNAMIC test that you cannot leave the site, you have to sit before the vials and observe whether there is any difference between sedimentation rates of the vials. Danile's pictures show just a snap shot which you can tell the difference in this process. 3. I am attaching a presentation to demonstrate the "observation process" of sedimentation rates. You will find additional explanations in the presentation.
