The most appropriate test for confirming the suspicion of neuroblastoma is Homovanillic acid (HVA) because it is a metabolite of dopamine produced by neuroblastoma cells. Elevated levels of HVA can indicate the presence of a neuroblastoma. The other tests listed are not specific for neuroblastoma and are used for other conditions.
