Police searching for four-year-old Madeleine McCann have been handed the first results of forensic tests.
The McCanns held talks with Spanish government officials
DNA and other samples were taken at sites in and around Praia da Luz in the Algarve from where Madeleine, from Leicestershire, went missing on 3 May.
UK police say they have received 1,000 images and 15,000 calls after an appeal to people who had been at the resort.
The information is being assessed and will be passed on to Portuguese investigators if thought relevant.
Portuguese police did not give specific details of the tests conducted at the Lisbon branch of the national forensic institute.
On Friday police took a DNA sample from Robert Murat, the only named suspect in the investigation.
But Portuguese Chief Inspector Olegario de Sousa said it was likely that this was because a previous sample given by Mr Murat had been lost, contaminated or was not of sufficient size.
Madeleine's parents, Gerry and Kate, spent the day with their two-year-old twins Sean and Amelie in Praia da Luz, swimming and visiting the beach.
On Friday, Mr and Mrs McCann were in Madrid, Spain, as part of a tour of several European countries to publicise the case.
The couple, from Rothley, Leicestershire, who met Pope Benedict in the Vatican City earlier this week, are due to visit the Netherlands, Morocco and Germany.
They held meetings with the UK ambassador to Spain, Denise Holt, and Spanish Interior Minister Alfredo Perez Rubalcaba.
There is speculation Madeleine could have been taken to Spain or passed through the country.
The couple also appeared on a Spanish television programme called Los Mas Buscados - or Most Wanted - which appeals for help to find missing people.
Spain has been preoccupied by its own case of child abduction - that of seven-year-old Yeremi Vargas, who disappeared in the Canary Islands two months ago.
As well as making their own plea, the McCanns were given a letter from the family of Yeremi Vargas.
The McCanns reiterated their appeal for information on Madeleine and urged people to visit their website, www.findmadeleine.com.
