  • Publication number: 20220111385
    Abstract: Blood sample collection and processing system (1) using a tube (102) and a holder (104) is described herein. The tube (102) includes a plasma separation system (114) for converting a whole blood sample into a plasma sample without using centrifugation. The plasma separation system (114) may comprise a microfluidic separation system such as a lateral cavity acoustic transducer system (113). The tube (102) is thereafter placed in the holder (104) for analysis regarding the plasma. The results of the analysis may be displayed to the user via a display screen (134) or an indicator of a different kind, to allow the user to determine whether the sample is sufficient with regards to volume, and/or quality for further use. Inasmuch as the analysis system (132) performs a rapid analysis of the plasma sample, the patient is still present and if the sample is insufficient, the healthcare provider can take another whole blood sample, counsel the client regarding the blood sample, or examine the patient further.

  • Publication number: 20210015414
    Abstract: Blood sample collection and processing system (1) using a tube (102) and a holder (104) is described herein. The tube (102) includes a plasma separation system (114) for converting a whole blood sample (129) into a plasma sample without using centrifugation. The plasma separation system (114) may comprise a filtration system such as a hollow fiber element (115). The tube (102) is thereafter placed in the holder (104) for analysis regarding the plasma. The results of the analysis may be displayed to the user via a display screen (134) to allow the user to determine whether the sample is sufficient for further use. Inasmuch as the analysis system (132) performs a rapid analysis of the plasma sample, the patient may still be present or in close proximity and if the sample is insufficient, the healthcare provider can take another whole blood sample (129), counsel the client regarding the blood sample (129), or examine the patient further.

  • Patent number: 10634588
    Abstract: The present invention relates to a reagent for the disruption of cell material, containing an internal standard that is completely integrated into the reagent for control and evaluation of the completeness of disruption of the cell material and subsequent steps, comprising a step selected from sample preparation, extraction, enrichment, isolation, purification, reverse transcription, amplification and detection of the cell components obtained from the disrupted cells, or a combination of a plurality or all of these steps.
