Morphology
The compound combines 'scratch' (a small skin mark/wound) and 'test' (an examination), so its meaning is directly compositional: a test that uses scratches. A B1 learner who knows the constituent words can readily infer this refers to a medical procedure applying scratches to the skin to check for allergic sensitivity, making the expression straightforward and cross-linguistically transparent.
Etymology
Scratch test comes from the simple, literal method doctors use: they make tiny skin scratches and put small drops of things that might cause an 'allergy' to see which spots go red. That's why a scratch test shows which things cause a 'reaction' or 'allergy'.
