Diagnosing Scalp Disorders: What Tests Can Help?
Published: Dec 27, 2023
When scalp issues arise, identifying the right tests can be crucial for a correct diagnosis. Discover the essential tests used to diagnose scalp disorders.
Physical Examination: The First Step
A thorough physical examination is often the first step in diagnosing scalp disorders. This includes checking for visible signs like scales, redness, or pustules. A full skin examination may also be necessary, as scalp conditions can affect other areas of the skin.
The Role of Scalp Biopsy
When clinical evaluation isn't enough, a scalp biopsy may be performed. This involves removing a small piece of scalp tissue for analysis. It can help diagnose conditions like cicatricial alopecia or confirm the presence of certain infections.
Laboratory Tests for Confirmation
Laboratory tests, such as fungal cultures or potassium hydroxide (KOH) preparations, can confirm infections like tinea capitis. These tests are crucial when the cause of the scalp disorder is not immediately apparent from a physical examination alone.
