There is a direct bus connection (N° 11) from the train station to the hospital Pellegrin where the lab is located. Alternatively, you can take the tramway (tram C) from the train station direction "Gare de Bruges" or "Parc des Expositions" until station "Porte de Bourgogne" (four stops), where you change for tram A direction "Le Haillan Rostand" until station "Hôpital Pellegrin" (ten stops).
