Anyone can access the BSCA website, but for those who haven’t renewed their membership after end March it is the membership section that they wont have access to.
Apologies, Catherine

As David says the references underlying best practice are in the NICE approved BSCA/BAD Cutaneous Allergy Service Standards – a service providing TRUE test alone would not meet these. It might be worth highlighting 2 publications. Contact Dermatitis 2012; 66:… Read more»

Dear Sharteen, A cross reaction is due to similar epitopes on the suspect allergen being in the non-suspect allergen. The level of actual reaction would not matter as you would still have the same motif on the suspect allergen as… Read more»
