Abstract

A urine sample testing apparatus may include a urine qualitative measuring section configured to acquire a measurement result for each of a plurality of urine qualitative measurement items and a urine sediment measuring section configured to acquire a measurement result for each of a plurality of urine sediment measurement items. The apparatus may also include an operation part that can specify a combination of one of the plurality of urine qualitative measurement items and one of the plurality of urine sediment measurement items. An information processing unit may be included and configured to determine whether a first measurement result of the urine sample obtained by the urine qualitative measuring section and a second measurement result of the urine sample obtained by the urine sediment measuring section have a predetermined relationship with respect to the urine qualitative measurement item and the urine sediment measurement item included in the specified combination.

First claim

What is claimed is:

1. A urine sample testing apparatus comprising:
a first measuring section configured to measure at least protein, albumin, creatinine and albumin/creatinine ratio in a urine sample;
a second measuring section configured to measure at least cast and red blood cell in the urine sample;
a display; and
a controller communicably connected to the first and second measuring sections and the display, and configured to:
determine whether a measurement value of albumin/creatinine ratio and a measurement value of cast have a predetermined relationship; and
show a determination result on the display.

2. The urine sample testing apparatus of claim 1 , wherein
the controller shows, as the determination result, an indication on the display when the measurement value of albumin/creatinine ratio and the measurement value of cast have the predetermined relationship.

3. The urine sample testing apparatus of claim 2 , wherein
the indication indicates that renal disease is suspected.

4. The urine sample testing apparatus of claim 3 , wherein
the renal disease is early diabetic renal disease.

5. The urine sample testing apparatus of claim 1 , wherein
the predetermined relationship is that the measurement value of albumin/creatinine ratio is higher than a threshold and the measurement value of cast is higher than a threshold.

6. The urine sample testing apparatus of claim 1 , wherein
the controller is configured to:
determine whether or not a measurement value of protein and a measurement value of red blood cell have a predetermined relationship; and
show, as the determination result, a second indication on the display when the measurement value of protein and the measurement value of red blood cell have the predetermined relationship.

7. The urine sample testing apparatus of claim 6 , wherein
the second indication indicates that renal disease is suspected.

8. The urine sample testing apparatus of claim 7 , wherein
the renal disease is chronic nephritis.

9. The urine sample testing apparatus of claim 1 , wherein
the screen includes a first region showing a measurement result obtained by the fist measuring section, a second region showing a measurement result obtained by the second measuring section, and a third region showing the determination result.

10. The urine sample testing apparatus of claim 1 , further comprising
a transporting section configured to transport a sample container which contains the urine sample, wherein
each of the first and second measuring sections aspirates the urine sample from the sample container transported by the transport unit and measure the aspirated urine sample.

11. The urine sample testing apparatus of claim 10 , wherein
the transporting section transports the sample container to the first measuring section before transporting the sample container to the second measuring section, and
the second measuring section aspirates the urine sample from the transported sample container when a measurement result obtained from the first measuring section meets a predetermined criteria.

12. The urine sample testing apparatus of claim 11 , wherein
the transporting section comprises:
a first tank region for storing a rack which holds a pre-measurement sample container;
a second tank region for storing a rack which holds a post-measurement sample container; and
a coupling region for coupling the first tank region and the second tank region, and

a position for aspirating the urine sample by the first measuring section and a position for aspirating the urine sample by the second measuring section are arranged at the coupling region.

13. The urine sample testing apparatus of claim 1 , further comprising
an operation part that is operable by a user to specify a combination of albumin/creatinine ratio and cast.

14. The urine sample testing apparatus of claim 13 , wherein
the controller is configured to show on the display an item setting screen, as the operation part, for specifying the combination of albumin/creatinine ratio and cast, and accept the specification of the combination through the item setting screen.

15. The urine sample testing apparatus of claim 14 , wherein
the item setting screen includes a relationship setting portion for setting the predetermined relationship for the specified combination,
the urine sample testing apparatus further includes a memory for storing the predetermined relationship set by the relationship setting portion.

16. An apparatus for processing a measurement result of a urine sample, comprising:
a measurement result acquiring unit configured to acquire a measurement result from a first measuring section which measures at least protein, albumin, creatinine and albumin/creatinine ratio in a urine sample, and configured to acquire a measurement result from a second measuring section which measures at least cast and red blood cell in the urine sample;
a display; and
a controller configured to:
determine whether a measurement value of albumin/creatinine ratio and a measurement value of cast have a predetermined relationship; and
show a determination result on the display.

17. A urine sample testing method comprising:
measuring at least protein, albumin, creatinine and albumin/creatinine ratio in a urine sample with a first measuring device;
measuring at least cast and red blood cell in the urine sample with a second measuring device;
determining whether a measurement value of albumin/creatinine ratio and a measurement value of cast have a predetermined relationship; and
showing a determination result on a display.

18. The urine sample testing method of claim 17 , wherein
an indication, as the determination result, is shown on the display when the measurement value of albumin/creatinine ratio and the measurement value of cast have the predetermined relationship.

19. The urine sample testing method of claim 18 , wherein
the indication indicates that renal disease is suspected.

20. The urine sample testing method of claim 19 , wherein
the renal disease is early diabetic renal disease.
