[A photometric method for the diagnosis of pregnancy in blood stains by determination of heat-stable alkaline phosphatase (EC 3.1.3.1). A modification of Oya, Asano and Fuwa's technique (author's transl)].
A quantitative method, described by Oya and coworkers was modified. In this way, venous blood from pregnant and nonpregnant women in blood stains can be reliably differentiated up to at least 19 months storage although as a qualitative test only. 1--3 cm2 of cloth stained with blood is needed and even less from placental blood stains.
