There where in the beginning of the EVG Laboratories a fail-diagnosis of TNS because some circumstands take place at same time - first of all, it was a swap-test, not a blood-test. Second, the probe was from very young puppies who are still succling so there could be some contamination. And at least, the probe need some weeks to reach the labor.

However - a test result must be 100% safe.  Therefore, during my contact with EVG regarding the ISDS-acceptance of EVG analysis, I asked to get a letter about there methods, if they had learned about this and how they control there probes to avoid mistakes.

 

Please see the letter (english and german) I received from the chief of the EVG Laboratories.
