The invention features methods for separating cells from a sample (e.g., separating fetal red blood cells from maternal method begins with the introduction of a sample including cells into one or more microfluidic channels. In one embodiment, the device includes at least two processing steps. For example, a mixture of cells is introduced into a microfluidic channel that selectively allows the passage of a desired type of cell, and the population of cells enriched in the desired type is then introduced into a second microfluidic channel that allows the passage of the desired cell to produce a population of cells further enriched in the desired type. The selection of cells is based on a property of the cells in the mixture, for example, size, shape, deformability, surface characteristics (e.g., cell surface receptors or antigens and membrane permeability), or intracellular properties (e.g., expression of a particular enzyme).

An assay device, a fluid analyte sample separator device and methods for use of thereof for determining whether the integrity of a fluid analyte sample has been compromised and for contemporaneously assaying the sample for the presence or absence of multiple analytes, such as drugs of abuse. The device is composed of a housing having separate slots therein for insertion of one or more analyte test strips, one end of which protrudes from the housing, and one or more units of a sample integrity monitoring system. The device may be used in dipstick or cassette form. An analyte sample separator for division of sample and retention of uncontaminated sample for further testing is also provided. The analyte test strips and sample integrity monitoring system are replaceable, so that the panel of analytes and of sample condition parameters tested can be customized.

Individual and aggregate test strip arrays having a backing strip supporting a flexible array substrate which supports an addressable collection of probes are taught. Hybridization cells for use with the individual test strip arrays are also disclosed, and in particular embodiments the hybridization cells closely fit a portion or all of the individual test strip arrays. Array hybridization systems that include test strip arrays and hybridization cells are disclosed with methods for performing a hybridization assay on a sample solution.

A method and apparatus for minimizing diagnostic errors due to transposition of biological specimens among subjects provides for independent biometric confirmation that a given specimen is from a given donor. In certain embodiments, a biological specimen confirmation kit comprises a portable and openable case housing components of the kit, at least one biological specimen container adapted to receive a biological testing specimen from a donor, and at least one reference sample device adapted to receive a biological reference specimen from the same donor, such that the testing and reference specimens can later be compared for donor match verification by a reference verification entity.

The present invention relates to apparatus and systems for isolating hazardous agents and organisms from their handlers and the public. In particular, the present invention relates to modular negative pressure biological containment chambers.

A platform or workstation comprising a plurality of various size holes and slots for holding blood specimens, test tubes, gel-cards and reagent bottles in an organized arrangement to simplify testing of the blood specimens and to eliminate the likelihood of human error. The platform comprises a top plate, a middle plate and a bottom plate which are spaced apart in a parallel plates arrangement. The top plate and the middle plate each comprise a plurality of holes in a matrix configuration for receiving blood specimen tubes and test tubes, and one or more columns of slots adjacent to the matrix configuration of holes for receiving gel-cards. Other size holes are provided for receiving the reagent bottles. The bottom plate only has screw holes for securing the top plate, middle plate and bottom plate together in the spaced apart relationship, and otherwise performs as a stop for articles inserted into the workstation holes. A first embodiment organizes all equipment needed to perform routine and complex testing in one space using 70 holes of 3 sizes and 3 slots in a predetermined arrangement. A second embodiment organizes blood specimens, test tubes and gel-cards in a row and stores reagents needed to perform tests using 57 holes of 3 sizes and 16 slots in a predetermined arrangement. A third embodiment organizes equipment for special studies and tests and uses 35 holes of 3 sizes and 12 slots in a predetermined arrangement.

Disclosed is an apparatus that allows for separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at various fractions in the apparatus. A buoy system that may include a first buoy portion and a second buoy member operably interconnected may be used to form at least three fractions from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient. Also selected fractions from the sample can be applied to a patient, either alone or as part of a mixture.

A system for testing an individual for illicit or other substances is described. The system operates in tandem with a mobile device (smartphone) application, which employs a camera of the mobile device to capture and record the self-administered specimen collection process for verification and rule compliance. The system guides the user through the process via on-screen prompts on the mobile device, and includes tracking of the collected specimen from the moment of collection until it is sealed in a tamper-proof container to be mailed for external testing at a lab. A breathalyzer may also be used with the system to test for the presence of alcohol in the user's body, the use of which is also monitored and recorded via the on-board camera of the mobile device for verification.

The present invention relates to a kit holding adapter (X1) for holding an analyzer (4) for analyzing a target analyte in a sample together with a sampling tool (5) used for taking a sample. The kit holding adapter (X1) includes a first holding portion (1) for holding the analyzer (4) and a second holding portion (2) for holding the sampling tool (5), for example. At least one of the first and second holding portions (1, 2) is preferably designed to expose a part of the analyzer (4) or the sampling tool (5) for performing the analysis of the sample with the analyzer (4) or for performing the sampling with the sampling tool (5) while the analyzer (4) or the sampling tool (5) are held by the adapter. The kit holding adapter (X1) may further include an article holding portion (3) for containing articles (45) used for at least one of the analyzer (4) and the sampling tool (5), or other articles used in conjunction with the analysis of the sample or the sampling.
