title: A microprocessor-controlled assay for the estimation of human placental lactogen.
abstract: A radioimmunoassay for human placental lactogen (HPL) is described using the KEMTEK 3000, which is a modular radioimmunoassay apparatus controlled by a microprocessor. Operation of the KEMTEK 3000 is largely automatic and it requires minimal intervention from the operator. It is capable of 300 reactions per hour so that a large number of estimations can readily be performed. HPL was assayed by a double antibody method on serum samples from pregnant women and patients with trophoblastic tumours.
