The most common skin patch test allergens found to be positive in North American dermatologic patients include all EXCEPT:

Nickel sulfate
Fragrance mix
Sodium chloride
Bacitracin

The correct answer is: Sodium chloride

Sodium chloride is not commonly found to elicit positive skin patch test reactions in North American dermatologic patients, unlike the other options listed. While nickel sulfate, fragrance mix, and bacitracin are common culprits for skin allergies, sodium chloride is not typically considered an allergen as it is found in normal physiological levels within the body. In addition, it is a common ingredient in many skincare and household products, making it even less likely to cause a skin reaction. Therefore, it is the least likely answer and the correct choice for this question.
