Which finding would a Wood lamp examination help identify?

• A. Fluorescent materials in the skin and hair
• B. Elastic fibers
• C. Capillary refill
• D. Melanin content

Answer: (A)

Wood lamp examination uses ultraviolet light to make certain substances in the skin or hair fluoresce. This helps reveal fluorescent materials produced by fungal elements or other pigments, making infections like tinea capitis or tinea versicolor easier to detect. Normal skin doesn't show the same fluorescence, so the appearance of fluorescence points to the presence of organisms or pigment-related substances. Elastic fibers, capillary refill, and melanin content aren’t identified by this fluorescence effect, so they aren’t the findings Wood lamp is best at revealing.
