“…Numerous studies over recent years have shown the usefulness of this technique for the in vitro diagnosis of allergic diseases (Ebo et al, 2006a(Ebo et al, , 2004aKleine-Tebbe et al, 2006) involving different allergens, such as inhalants (Paris-Köhler et al, 2000;Saporta et al, 2001), hymenoptera venoms (Sabbah et al, 1998;Sainte-Laudy et al, 2000), or latex (Ebo et al, 2002;Sanz et al, 2003). For the diagnosis of allergy to drugs like muscle relaxants (Abuaf et al, 1999;Monneret et al, 2002), betalactam antibiotics (Sanz et al, 2001b(Sanz et al, , 2002aTorres et al, 2004), pyrazolones (Sabbah et al, 1997;Sanz et al, 2005) and non steroidal anti-inflammatory drugs (NSAIDs) BAT has opened up an important diagnostic pathway, either on its own or combined with other techniques (de Weck et al, 2008b;Gamboa et al, 2003a), allowing avoidance of challenge tests in an important number of cases (Hausmann et al, 2009;Sanz et al, 2009).…”
