Embodiments of the system can include: a base substrate; and an array of sample processing regions defined at a broad surface of the base substrate, wherein each of the array of sample processing regions includes: a set of microwell subarrays arranged in a gradient by volumetric capacity between an upstream end and a downstream end of each respective sample processing region, and a boundary separating each respective sample processing region from adjacent sample processing regions. The system can support methods, with example implementation by an automated platform, for returning preliminary results from a subset of microwells of the samples processing regions, as well as results pertaining to specific and non-specific amplification, for multiple targets of a sample.

Bodily fluid sample collection and transport

Bodily fluid sample collection systems, devices, and method are provided. The sample is collected at a first location and subjected to a first sample processing step. The sample may be shipped to a second location and subjected to a second sample processing step that does not introduce contaminants into a plasma portion of the sample formed from the first processing step. The sample may also be mixed with other material(s) in the collection device.

NUCLEIC ACID AMPLIFICATION CHIP

In a nucleic acid amplification chip, a filter is provided inside or outside a PCR reaction container with respect to a micro-flow channel. Here, the filter is fixed to the PCR reaction container via a fixing portion. In this case, since the fixing portion is formed, the reliability of fixing the filter to the PCR reaction container can be improved. For this reason, the leakage of an evaporated sample solution (aerosol) from a gap between the filter and the PCR reaction container can be suppressed. Further, since the fixing portion is formed, the leakage of the evaporated sample solution (aerosol) can be suppressed without increasing the thickness of the filter, so that the filter can be made thin. As a result, the overall thickness of the nucleic acid amplification chip can also be reduced, so that the degree of freedom in designing the nucleic acid amplification chip is improved.

Performing sample quantitation and sample amplification may be performed in a sample cartridge or sample cartridges. Sample quantitation using qPCR may be performed during STR PCR on the sample. Samples need not be normalized prior to performing STR PCR. In certain embodiments, qPCR and STR PCR are performed on the same cartridge, optionally at the same time (or in real-time, or overlapping in time) and optionally using some or all of the same PCR apparatus. In other embodiments, qPCR and STR PCR are performed on different cartridges. Quantitation of the STR PCR sample may be performed without substantially delaying the STR PCR process.
