&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Screening children for catecholamine-secreting tumors involves collecting random urine samples for vanillylmandelic acid (VMA) testing. This test helps in screening for such tumors and supports the diagnosis of neuroblastoma. Additionally, it is used to monitor patients who have undergone treatment for neuroblastoma.&lt;/span&gt;&lt;/p&gt;
