A significant linear correlation was found between serum total porphyrin concentration and 24-hour total urinary porphyrin excretion in 18 patients with porphyria cutanea tarda sampled at diagnosis and during and after treatment on 73 occasions. This confirms that the serum porphyrin level parallels urinary porphyrin excretion and is an appropriate indicator of disease activity useful for monitoring patients in clinical practice.
在18例迟发性皮肤卟啉病患者诊断时、治疗期间及治疗后共73次采样中，发现血清总卟啉浓度与24小时尿总卟啉排泄量之间存在显著的线性相关性。这证实血清卟啉水平与尿卟啉排泄量平行，是疾病活动的合适指标，有助于临床实践中对患者进行监测。
