Most likely it means Swiss experts to come in and take samples - and test in Swiss

Swiss experts have been invited to the West Bank to test Yasser Arafat’s remains for possible poisoning, the chief investigator looking into the 2004 death of the Palestinian leader said Wednesday.

Tawfik Tirawi, the chief Palestinian official investigating Arafat’s death said the Palestinians asked the Swiss lab for help. The lab confirmed that.

“We are currently studying how to adequately respond to this demand,” Darcy Christen, a spokesman for the Swiss institute, said Wednesday. “Meanwhile, our main concern is to guarantee the independence, the credibility and the transparency of any possible involvement on our side,” she said.
