Interference of pregnancy steroid hormones with FPN test for estimation of some phenothiazine derivatives in urine has been investigated. The FPN test was positive in 97.9% of urine samples obtained from pregnant women. It is supposed that metabolites of estrogens and progestagens present in higher amounts in urine samples of these women are responsible for this positivity.
已对妊娠甾体激素对用于估算尿液中某些吩噻嗪衍生物的FPN试验的干扰进行了研究。从孕妇获得的尿液样本中，97.9%的样本FPN试验呈阳性。据推测，这些女性尿液样本中雌激素和孕激素的代谢产物含量较高，导致了这种阳性结果。
