Atopic Dermatitis (AD) vs. Psoriasis (PS)
Confirm the inflammatory signature of clinical trial participants. AD vs. PS differentiates Atopic Dermatitis from Psoriasis.
Atopic dermatitis (AD) and Psoriasis (PS) exist on a spectrum of inflammation and often exhibit common clinical and histologic features, making them difficult to distinguish visually.1 AD is the most common type of eczema, affecting approximately 10% of the US population, approximately 9.6 million children and 16.5 million adults.2 PS affects more than 3% of the US adult population, nearly 7.5 million US adults.3
The DermTech® Smart Sticker® enables non-invasive collection of epidermal samples from lesional skin for subsequent gene expression analysis. The AD vs PS assay offers the ability to differentiate the two most common inflammatory diseases using a molecular signature of four key genes.
The ability to distinguish these two inflammatory conditions may provide a valuable tool for biomarker-driven disease differentiation and confirmation in clinical trials and may be utilized for the personalized treatment of AD and PS patients in a clinical trial setting.
