no wonder G.A....regrets using the Birmingham lab...
still very vocal IMO ...because h has nothing to hide
As to DNA evidence that was discovered in the McCanns’ rental car, Amaral was adamant that this could have been more thoroughly tested. While initial findings on blood were deemed inconclusive, Amaral explains hair samples were simply not followed up as British lab technicians claimed it was impossible to test hair samples without roots.
“It is possible, and even at the time it was possible!” Amaral insisted.
“These hair samples are in Portugal! They were returned in Portugal and they are in the files. It’s simple! All the public ministry has to do is take the hairs and send them to a European laboratory, or anywhere where these kinds of exams are done without roots.”

Erm. DNA was never his forte... Research into extracting nuclear DNA from hair shafts appears to be technically possible in some circumstances (albeit with a relatively low success rate), and research
is advancing in that direction. Whether or not the techniques are now sufficiently mainstream commercialised routine tests remains to be seen (I haven't found anything to that effect - only that it is possible).
Even if certain specialised services can do so, it is likely to be very expensive. One or more of her hair fragments could have been in the car by virtue of the fact of simply moving family belongings in the car (clothing, toys, anything). What would be the point in spending limited funds to prove that even one of the many hair fragments in the car boot belonged to Madeleine?
I'd be more interested in the hairs in the apartment. But some of those seem to have disappeared somewhere between when the PT forensic team took photos and when the envelope arrived at the lab *.
Even then it would probably only be done if there was a specific suspect.
