Hematology analyzer, method, and system for quality control measurements
First Claim
1. A hematology analyzer for measuring a blood sample, the hematology analyzer comprising:
- a display;
measurement hardware configured to measure blood constituents contained in a blood sample collected from a subject; and
a controller in communication with the display and the measurement hardware, the controller configured to;
control the display to indicate an instruction to implement a first quality control (QC) measurement on a first vial containing a first QC sample;
control the display to indicate an instruction to repeat the first QC measurement on the first vial if a result of the first QC measurement on the first QC sample by the measurement hardware is not within a first predetermined range and a number of times that the result of the first QC measurement is not within the first predetermined range is less than a predetermined number greater than one;
control the display to indicate an instruction to implement a second QC measurement on a second vial that contains a second QC sample having a consistency that substantially matches the first QC sample of the first vial if the result of the first QC measurement on the first QC sample, by the measurement hardware, that has been measured is not within the first predetermined range and the number of times is greater than or equal to the predetermined number;
control the display to indicate an instruction to implement a third QC measurement on a third vial that contains a third QC sample having a different concentration from the first QC sample if a result of the second QC measurement on the second QC sample, by the measurement hardware, that has been measured is within the first predetermined range; and
control the measurement hardware to allow measurements of the blood sample collected from the subject to be performed if a result of the third QC measurement on the third QC sample, by the measurement hardware, that has been measured is within a second predetermined range.

Abstract
An analyzer for measuring a sample includes a display, measurement hardware configured to perform a quality control measurement on a vial containing a quality control (QC) sample, and a controller. The controller is in communication with the display and the measurement hardware and is configured to communicate, via the display, instructions to implement a QC measurement on a first vial containing a first QC sample. If a result of the QC measurement is within a pre-determined range the first vial passes the QC measurement. If the result of the QC measurement is not within the pre-determined range the first vial fails the QC measurement. If the first vial fails the QC measurement and if a number of times the first vial fails the QC measurement is less than a predetermined number, the controller is configured to communicate, via the display, instructions to repeat the QC measurement on the first vial.

11. A method for measuring a blood sample, comprising:
-
measuring, by measurement hardware of a hematology analyzer, blood constituents contained in a blood sample collected from a subject; and displaying, on the hematology analyzer, an instruction to implement a first quality control (QC) measurement on a first vial containing a first QC sample; displaying, on the hematology analyzer, an instruction to repeat the first QC measurement on the first vial in response to a result of the first QC measurement on the first QC sample by the measurement hardware is not within being outside of a first predetermined range and a number of times that the result of the first QC measurement is not within the first predetermined range being less than a predetermined number greater than one; and displaying, on the hematology analyzer, an instruction to implement a second QC measurement on a second vial that contains a second QC sample having a consistency that substantially matches the first QC sample of the first vial in response to the result of the first QC measurement on the first QC sample, by the measurement hardware, that has been measured being outside the first predetermined range and the number of times being greater than or equal to the predetermined number; displaying, on the hematology analyzer, an instruction to implement a third QC measurement on a third vial that contains a third QC sample having a different concentration from the first QC sample in response to the result of the second QC measurement on the second QC sample, by the measurement hardware, that has been measured being within the first predetermined range; and controlling the measurement hardware to allow measurements of the blood sample collected from the subject to be performed in response to a result of the third QC measurement on the third QC sample, by the measurement hardware, that has been measured being within a second predetermined range. - View Dependent Claims (12)

13. A system comprising:
-
a hematology analyzer for measuring a blood sample; and a server in communication with the hematology analyzer via a network, the hematology analyzer comprising; a display; a barcode reader; measurement hardware configured to measure blood constituents contained in a blood sample collected from a subject; and a controller in communication with the display and the measurement hardware, the controller configured to; control the display to indicate an instruction to implement a first quality control (QC) measurement in which the measurement hardware measures a quantity of a substance in a first QC sample contained in a first vial having a first barcode; communicate with the server to send data of the first barcode read by the barcode reader and to receive a first known quantity of the substance in the first QC sample; control the display to indicate an instruction to repeat the first QC measurement on the first vial if a result of a first QC measurement on the first QC sample by the measurement hardware is not within a first acceptable range of the first known quantity and a number of times that the result of the first QC measurement is not within the first acceptable range is less than a predetermined number greater than one; control the display to indicate an instruction to implement a second QC measurement in which the measurement hardware measures a quantity of a substance in a second QC sample which is contained in a second vial having a second barcode and has a consistency that substantially matches the first QC sample of the first vial if a result of the first QC measurement on the first QC sample, by the measurement hardware, that has been measured is not within the first acceptable range and the number of times is greater than or equal to the predetermined number; communicate with the server to send data of the second barcode read by the barcode reader and to receive the first known quantity of the substance in the second QC sample; control the display to indicate an instruction to implement a third QC measurement in which the measurement hardware measures a quantity of a substance in a third QC sample which is contained in a third vial having a third barcode and contains a different quantity of the substance in the first QC sample if a result of the second QC measurement on the second QC sample, by the measurement hardware, that has been measured is within the first acceptable range of the first known quantity; communicate with the server to send data of the third barcode scanned by the barcode reader and to receive a second known quantity of the substance in the third QC sample; and control the measurement hardware to allow measurements of the blood sample collected from the subject to be performed if a result of the third QC measurement on the third QC sample, by the measurement hardware, that has been measured is within a second acceptable range of the second known quantity. - View Dependent Claims (14)
