Abstract: A method of determining a limit of detection and a limit of quantitation in a nucleic acid detection test is provided, the method including, by using a container having a specific configuration, adding a negative specimen that does not contain target nucleic acids to a positive control group and adding a reagent used for a nucleic acid detection test to a negative control group and the positive control group to amplify the target nucleic acids, and determining a smallest specific copy number among specific copy numbers with a detection rate of 95% or greater in the positive control group as a limit of detection and determining a smallest specific copy number among specific copy numbers with CVln of 35% or less as a limit of quantitation in a case where the target nucleic acids are not detected in the negative control group.

Abstract: An information provision device includes an acquisition unit and an information output unit. The acquisition unit acquires test result data indicating a Cq value of a well obtained by a test device performing a polymerase chain reaction (PCR) test on a standard device having the well in which a known number of copies of a nucleic acid are disposed. The information output unit outputs comparison information obtained by comparing information obtained from evaluation target data that is the evaluation target data of an evaluation target with information obtained from one or more pieces of the test result data different from the evaluation target data.

Abstract: Provided is a technique capable of adequately presenting the product specifications of a material sample even when the concentration distribution of the material is asymmetrical. A material sample according to the present disclosure stores a material having variation according to a probability distribution. As the product specifications of the material sample, the representative value of the probability distribution as well as an interval in which the amount of the material is greater than or equal to a target probability on the probability distribution is displayed.

Abstract: A particle counting apparatus is provided that includes: a droplet discharger configured to discharge a droplet containing at least one luminescent particle capable of emitting light upon receiving light; a light irradiator configured to irradiate the droplet discharged by the droplet discharger with light; at least one light receiver configured to receive light emitted by the at least one luminescent particle irradiated with the light emitted by the light irradiator; and circuitry configured to count luminescent particles contained in the droplet based on the light received by the at least one light receiver, the circuitry being configured to measure a presence or absence of the luminescent particles contained in the droplet; and to measure a number of the luminescent particles contained in the droplet.
