Abstract: A method is provided that allows a subject to be diagnosed as having one of a variety of hypertensive states, including pre-eclampsia, based on the measurement of a plurality of factors including the level of soluble fms-like tyrosine kinase 1 (sFlt-1), an obesity factor and optionally one or more additional factors, which may be physiological parameters or biomarkers. The method can be used to determine hypertensive states associated with pregnancy, or associated with anti-angiogenic drug therapy. The method is thus useful for diagnosing the hypertensive status of pregnant women, as well as patients undergoing anti-angiogenic treatment (e.g., chemotherapy).

Abstract: Method of measuring the quantity of a first proteinaceous specific binding partner (sbp) in a biological sample comprising detecting the binding of the first proteinaceous sbp with a labeled second proteinaceous sbp, wherein neither the first or second sbp is an antibody or fragment thereof, which is preferably a method of determining the amount of sFlt-1, particularly free sFlt-1, and the amount of PlGF, particularly free PlGF, in a sample, which is preferably used in a method of predicting risk of preeclampsia comprising comparing free PlGF to free sFlt-1.

Abstract: A system for electrochemical measurement of glucose concentration in an undiluted test sample, e.g. blood is provided containing a sensor including a three-layered contiguous membrane. The membrane has a thickness of 50 to 130 microns, and is composed of a 1 to 10 micron thick first layer, a 10 to 30 micron thick second layer having an average pore diameter of 15 nanometers and a 40 to 80 micron thick third layer containing glucose oxidase. The third layer is less dense than the first and second layers and the first layer is more dense than the second layer. The layers of the membrane are fused together such that no clear distinction can be made between the layers at the boundary. The sensor is calibrated in a standard glucose solution which includes catalase as a hydrogen peroxide scavenger, and the sensor has a response that is linear throughout the concentration range of glucose in an undiluted sample.
