Patient's question:
Diagnosing pediatric Henoch-Sch?nlein purpura, what tests are needed? How should pediatric Henoch-Sch?nlein purpura be treated?Doctor's answer:
First, blood tests are conducted to check immune system indicators such as T cell subsets, B cell subsets, and immunoglobulins. Next, if allergies are suspected, many allergen tests may be performed, but this test is not commonly done. Additionally, a routine urine test is conducted to carefully observe any potential kidney function damage. Some parents may overly worry about kidney function damage and may frequently retest urine routines, but this is actually unnecessary. Generally, during the acute phase, a test is done once a week, and during the recovery phase, a test is done once a month. There is no need to check urine routines every day. This is like measuring a child's height—there is no need to measure it every day; measuring it at intervals is sufficient.
