Sample analyzer, sample analyzing method, and computer program product
First Claim
1. A sample analyzer comprising:
- a sample preparation section for preparing a measurement sample from an undiluted biological sample and a reagent;
a detector for detecting an analyte contained in the measurement sample prepared by the sample preparation section; and
a controller in communication with the sample preparation section, the controller being configured to1) control the sample preparation section so as to obtain a first amount of an undiluted biological sample from a first sample container, and prepare a first measurement sample of a first dilution ratio, when the undiluted biological sample in the first sample container is ordinary amount; and
2) control the sample preparation section so as to obtain a second amount of an undiluted biological sample from a second sample container, the second amount being less than the first amount, and prepare a second measurement sample of a second dilution ratio higher than the first dilution ratio, when the undiluted biological sample in the second sample container is small amount.

Abstract
The present invention is to present a sample analyzer which is automated even when measuring a small amount sample and is capable of improving a measurement precision. The sample analyzer S comprises a sample preparation section for preparing a measurement sample; a detector D3 for detecting an analyte contained in the measurement sample; and a controller 100 being configured to 1) control the sample preparation section so as to prepare a first measurement sample of a first dilution ratio, when measuring an ordinary amount sample; and 2) control the sample preparation section so as to prepare a second measurement sample of a second dilution ratio higher than the first dilution ratio, when measuring a small amount sample.

11. A sample analyzing method in a sample analyzer being capable of analyzing a biological sample, comprising:
-
a first step of obtaining a first amount of an undiluted biological sample from a first sample container, and preparing a first measurement sample of a first dilution ratio from the obtained undiluted biological sample and a reagent, when the undiluted biological sample in the first sample container is ordinary amount; a second step of obtaining a second amount of the undiluted biological sample from the second sample container, the second amount being less than the first amount, and preparing a second measurement sample of a second dilution ratio higher than the first dilution ratio from the obtained undiluted biological sample and the reagent, when the undiluted biological sample in the second sample container is small amount; and a third step of detecting an analyte contained in the measurement sample prepared in the first step or the second step. - View Dependent Claims (12, 13, 14, 15)

16. A computer program product for enabling a computer to execute a sample analyzing method in a sample analyzer which is capable of performing analysis of a biological sample, comprising:
-
a computer readable medium; and software instructions, on the computer readable medium, for enabling the computer to perform predetermined operations comprising; a first step of obtaining a first amount of an undiluted biological sample from a first sample container, and preparing a first measurement sample of a first dilution ratio from the obtained undiluted biological sample and a reagent, when the undiluted biological sample in the first sample container is ordinary amount; a second step of obtaining a second amount of the undiluted biological sample from the second sample container, the second amount being less than the first amount, and preparing a second measurement sample of a second dilution ratio higher than the first dilution ratio from the obtained undiluted biological sample and the reagent, when the undiluted biological sample in the second sample container is small amount; and a third step of detecting an analyte contained in the measurement sample prepared in the first step or the second step. - View Dependent Claims (17, 18, 19, 20)
