North American Series Update

 
In a significant stride towards advancing dermatological research and enhancing patient care, the North American Series (NA-1000 and NAC-80) used for baseline patch testing have undergone major updates.

The 2024 version of the series introduces a new format of placing all non-liquid haptens in alphabetical order by article number. The 10 liquid haptens are all placed on a single Patch Test Unit to facilitate application. Compared to the previous edition, 22 haptens have been replaced in the North American Comprehensive (NAC-80) series with haptens that are showing increased potential for diagnosing patient reaction. In the North American Baseline (NA-1000) series, 10 haptens have been replaced and an additional 10 have been added making a total of 60 haptens on this series. Please consult the 2024 Catalogue Amendments link for specific deletions and additions. The North American Extended (NAE-65) series is no longer available.
