摘要:
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.

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.

摘要:
A portable-blower duct has a bendable portion whose inner peripheral surface is a cylindrical surface without any protrusions or recesses in a normal state or in an expanded state, that is, unless it is greatly curved. With this construction, no turbulence is generated in air passing through a tube, thereby making it possible to suppress pressure loss. Thus, the flow velocity of air guided through the duct is not reduced, thereby suppressing a deterioration in air blowing efficiency. Even when the tube is curved, the outer side of the curved portion is expanded, and the corresponding portion of the inner peripheral surface remains a smooth surface, thus making it possible to minimize the air pressure loss.
