WO/2015/074634 APPARATUS AND METHOD FOR ACHIEVING LOGARITHMIC TESTING EFFORT IN SERIES TESTING OF LIQUID OR GASEOUS SAMPLES||WO||28.05.2015|
||PCT/DE2014/000274||TAEGER, Thomas||TAEGER, Thomas|
Even with a small proportion of positive samples, previous series tests have often worked with linear effort, as a result of pipetting have required complex apparatus and entailed the risk of cross contamination, have rarely used direct test methods such as PCR and, when antibody tests are used, have had long latency times. In order to achieve logarithmic testing effort in series testing of liquid or gaseous samples, with preferably amplifying, direct test methods, involving as little effort as possible, the individual samples are introduced into a tree-like apparatus with connected sample chambers, which according to further refinements of the invention are provided with metering and cycling functions by means of siphons, and the samples and connecting lines of which are covered with oil or the like, largely automatically, to prevent cross contaminations. Application areas include veterinary-medical, hygiene-related or microbiological series tests in clinical/chemical laboratories, including on a small budget and in a simple infrastructure.
