title: Interference of pregnancy steroid hormones with FPN test for estimation of phenothiazine derivatives in urine.
abstract: 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.
