This is highly unlikely if they adhere to the standard protocols around the world but this very well could be the case:
Italy is the one of the only European countries that has not signed on to the Prum Convention, which establishes protocols and certification standards for DNA testing. Italy has no labs that meet the certification requirements applied throughout the rest of western europe
Italy's inability to meet certification requirements and continuing refusal to sign on to the convention have been topics of discussion within the EU for some time
These are only 9 of noted errors specific only to the LCN DNA
nine distinct ways, Stefanoni's improv LCN DNA profiling was even worse than unproven and inadmissible LCN DNA profiling tests.
1. The DNA wasn't amplified enough; the very weak fluorescence was simply blown up.
2. The test site was not remote from other DNA tests to avoid contamination.
3. Specialized LCN-quality entry procedures to avoid contamination were not used.
4. A positive pressure environment was not maintained to exclude contamination.
5. Special LCN sterilization procedures to destroy errant DNA were not used.
6. The entire sample was consumed in a single test; no comparison of tests was possible.
7. No sample was retained for future reference. The test can never be reproduced.
8. No negative control tests were run to check for contamination.
9. No control tests to check for field contamination were performed
Only a couple of labs in the US require blind testing ... why do you expect it in Italy?
Here is the definition <modsnip>
A blind or blinded experiment is a scientific experiment where some of the persons involved are prevented from knowing certain information that might lead to conscious or unconscious bias on their part, invalidating the results
