In 2007, partial tests were performed on 25 samples of blood and saliva. 

Experts at the National Institute for Legal Medicine (INML) analysed 444 hairs that were collected by the Polícia Judiciária during the months after Madeleine McCann's disappearance, in 2007, in Praia da Luz, Lagos. As far as CM [Correio da Manhã] was able to establish, further 25 samples of blood and saliva and three other residues that were found inside the bedroom where the child disappeared from and in the boot of a car were also subject to forensic tests. Scotland Yard now wants to take some of these residues to England, to have them analysed again at a private British lab. 

As CM reported yesterday, the Englishpeople also want to re-test a curtain from the room where Maddie slept, which was subject to tests by the INML in 2007, and where nothing relevant was found. The collection of traces was performed at houses, cars and on sofas by experts from the PJ's Scientific Police Lab.

Among the traces are also hair and saliva samples from several persons that were considered to be important to the investigation.

From the list of 444 hairs that were subject to testing, 432 are human and 12 are non-human, 98 failed to match any DNA profile and 19 produced partial results. The request to re-evaluate the traces will be part of a 6th letter rogatory, despite the fact that there is still no decision from the new prosecutor at the Public Ministry in Portimão, Inês Sequeira, for the 5th letter that was sent to Portugal by the British.
