 Differential diagnosis refers to the characterization of the underlying cause of pathological states based on specific tests.
 Differential WBC count is the enumeration of each type of white blood cells either manually or using automated analyzers.
Mathematics
 Differential (calculus), multiple related meanings in calculus and differential geometry, such as an infinitesimal change in the value of a function

 In traditional approaches to calculus, the differential of a function represents an infinitesimal change in its value and employs the dx, dy, dt, symbols.
 In differential geometry, differentials represent the exterior derivatives of the coordinate functions on a differentiable manifold.
 Differential (coboundary), in homological algebra and algebraic topology, one of the maps of a cochain complex
 Differential (cryptography), in differential cryptanalysis, a pair consisting of the difference, usually computed by XOR (exclusive or), between two plaintexts, and the difference of the corresponding ciphertexts
 ''See also derivative, differential calculus.
