<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">analysis site</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for lab that I've seen before include "Scientists' workplace" , "Science workshop" , "Workplace for researcher" , "Scientist's workroom" , "Workplace for scientific research, in short" .)
