Patent ID: 11952620
Assignee: KABUSHIKI KAISHA TOSHIBA
Field: Chemical engineering (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 1:
2. The device of Claim 1, further comprising a memory and a processor, which are electrically connected with each other and the measurement unit wherein
the processor is configured to:
read a program for controlling the measurement unit from the memory,
produce measurement data from the detection signal with the measurement data including a rise time of the detection signal,
store the measurement data in the memory,
quantify the target nucleic acid in a sample based on the measurement data,
read the measurement data stored in the memory;
determine whether each of the plurality of the detection regions is a positive region where amplified produces exist in the vicinity or a negative region where no amplified products exist in the vicinity,

wherein
a region among the plurality of detection regions where: the rise time ofthe detection signal is shorter than that in the other detection regions is determined to be the positive region, and
a region among the plurality of detection regions where the rise time of the detection signal is longer than that in the other detection regions is determined to be the negative region;
total the number of the positive and the number of the negative regions;
determine, when the number of the detection regions exhibiting the positive value is 0, that the target nucleic acid does not exist in the sample;
calculate the quantity of the target nucleic acid present in the sample, when both of the positive regions and the negative regions exist, from the number of the positive regions exhibiting; and
calculate the quantity of the target nucleic acid in the sample, when all the detection regions are the positive regions, from the rise time of the signal and
store the calculated value of the quantity of the target nucleic acid in thy; sample in the memory.
