Is Fluorescence Under an Alternate Light Source Sufficient to Accurately Diagnose Subclinical Bruising?

This single‐blinded, randomized validation study was conducted to evaluate whether fluorescence under alternate light sources ( ALS ) is sufficient to diagnose subclinical bruising (bruising not visible under white light). Standardized trauma was induced on randomly selected ventral forearms. On days 1, 7, and 14 investigators independently examined case forearms under white light for perceived bruising and under ALS for fluorescence and...
