Provided is a portable diagnostic test apparatus including: an accommodation portion including an outer side, an inner side, and an accommodation space provided on the inner side; a hinge; and a main body coupled to the accommodation portion by the hinge, where the portable diagnostic test apparatus is configured to be opened and closed by rotating one of the accommodation portion and the main body about the hinge, and where the main body is configured to obtain a result of a measurement based on data collected from drawn blood. The main body and/or the accommodation portion includes at least one strip keeping portion configured to store at least one strip. The at least one strip keeping portion may include: a housing; a discharge portion; and a first movement portion configured to move one of the strips to the discharge portion.

Portable diagnostic test apparatus

A microfluidic device having a delay structure and a sample testing apparatus including the microfluidic device are provided. The microfluidic device includes: a reaction chamber which contains a reagent capable of reacting with a sample; a distribution channel through which the sample is provided to the reaction chamber; an inlet channel through which the at least one reaction chamber is connected with the distribution channel; and a delay structure which is located between the at least one reaction chamber and the distribution channel, and delays movement of contents of the reaction chamber to the distribution channel.

Micro-fluidic device and sample testing apparatus using the same

A microfluidic apparatus having an additional chamber containing material configured to prevent cross contamination between reaction chambers contained therein, and a control method thereof are provided. The microfluidic apparatus includes a sample chamber configured to accommodate a sample, a plurality of reaction chambers each configured to accommodate a reagent, a distribution channel configured to distribute the sample into the plurality of reaction chambers, a mixture prevention chamber connected to the distribution channel and containing a mixture prevention material configured to prevent the reagents accommodated in the plurality of reaction chambers from being mixed with each other, and a valve disposed within the distribution channel and configured to open and close the distribution channel.

Microfluidic apparatus and control method thereof

A microfluidic device having a chamber with a fluid discharge configuration is provided. The microfluidic device includes a platform including a chamber configured to accommodate a fluid therein. The chamber includes an inner sidewall and an outer sidewall disposed outwardly from the inner sidewall in a radial direction of the platform. The outer sidewall includes a first point located closest to a center of the platform, and a second point located farthest from the center of the platform. A distance from the center of the platform to an arbitrary third point on the outer sidewall between the first point and the second point increases from the first point to the second point, so that the fluid near the first point is guided to the second point by centrifugal force during rotation of the platform.

Microfluidic device

Disclosed are a centrifugal micro-fluidic structure for measuring glycated hemoglobin, a centrifugal micro-fluidic device for measuring glycated hemoglobin, and a method for measuring glycated hemoglobin. According to the disclosure, immunosorbent assay and affinity measurements are simultaneously conducted using only a single device in order to detect hemoglobin variants or interfering substances and, therefore, the detected results are applied to analysis of measurement results so as to eliminate and/or compensate for, or calibrate errors in measurement of, glycated hemoglobin, thereby more accurately measuring the glycated hemoglobin.
