Abstract: Techniques are provided for determining settings of a dPCR experiment for the detection of a chromosomal aneuploidy in a plasma sample from a female pregnant with a fetus. Data about the sample, the dPCR process, and a desired accuracy can be used to determine the settings. Such settings can include a minimal input number of control chromosome molecules for the dPCR experiment, a minimal number of control chromosome molecules for a pre-amplification procedure, and a number of PCR cycles in the pre-amplification procedure. These settings can be used to satisfy the accuracy specified by the accuracy data. Thus, the dPCR experiment can be designed to achieve the desired accuracy while reducing cost, e.g., by not using more of a sample than needed and not performing more pre-amplification than needed or performing more manipulations than needed.

Abstract: Disclosed are methods of measuring moisture. Specifically, methods of measuring moisture on dry or nearly dry surfaces using an electrochemical sensor are disclosed. The method comprises applying a coating comprising an electrolyte to an electrode wherein water in the air can permeate the coating, applying a voltage to the electrode, detecting a current and, determining if the current indicates the presence of moisture. As a voltage is applied, oxygen in the water is reduced and produces a measurable signal. The method includes measuring the amount of or decrease of dissolved oxygen (in the form of water) at the surface of the electrode over time. Reduction of oxygen acts as a surrogate for water/moisture and, as such, the dryness of the surface of the electrode is calculated based on a predetermined relationship between current and dissolved oxygen (in the form of water).

Abstract: The subject disclosure provides systems, computer-implemented methods, and clinical workflows for meso-dissection of biological specimens and tissue slides by incorporating annotation and inter-marker registration modules within digital pathology imaging and meso-dissection (or milling) systems. Images of a reference slide a milling slide may be acquired using the same imaging system, with the annotations on the image associated with the milling slide being based on the inter-marker registration. Each image along with its respective annotations and meta-data may be associated with a project or a case, and stored in an image management system. A same-marker registration may be used to map annotations from the annotated image of the milling slide to a live image of the milling slide. The milling slide may be milled based on the annotations, with milled tissue output into a contained that is labeled in association with the labeled input slides.
