## Abstract

Provided is a medical test slide unit including a frame main body including: a marker part which has a thin plate shape and in which a plurality of position indicating markers are formed longitudinally and transversely; and a border part arranged to surround the marker part, wherein a step is formed between the border part and the marker part to form a seating recess, and wherein a slide, on which a specimen to be examined using a microscope is placed, is selectively seated in the seating recess.

## Claims

### Claim 1

A medical test slide unit comprising a frame main body, wherein the frame main body comprises:
a marker part having a thin plate shape and comprising a plurality of position indicating markers formed longitudinally and transversely; and
a border part surrounding the marker part, wherein a step is formed between the border part and the marker part to form a seating recess,
wherein the seating recess is configured to seat therein a slide, on which a specimen to be examined using a microscope is located,
wherein the border part comprises a rail groove for facilitating coupling and separation of the border part and the marker part by guiding movement of the marker part, and
wherein the slide is selectively located in the seating recess of the frame main body to be attachably or detachably coupled to or from the frame main body, and the specimen to be examined using the microscope is located in a position corresponding to one or more of the plurality of position indicating markers.

### Claim 2 (depends on 1)

The medical test slide unit of claim 1, wherein the marker part of the frame main body further comprises, in addition to the plurality of position indicating markers, a guide marker for identifying a position or a focus of the microscope.

### Claim 3 (depends on 2)

The medical test slide unit of claim 2, wherein the position indicating markers and the guide marker of the marker part are each formed as through holes.

### Claim 4 (depends on 2)

The medical test slide unit of claim 2, wherein the guide marker of the marker part is formed as a through hole.

### Claim 5 (depends on 3)

The medical test slide unit of claim 3, wherein the marker part comprises an exposure recess that is not overlapped by the slide when the marker part and the slide are stacked on each other, and the exposure recess facilitates separation of the slide seated in the seating recess from the frame main body.

### Claim 6 (depends on 5)

The medical test slide unit of claim 5, wherein the border part of the frame main body further comprises a cut recess through which an exterior of the border part communicates with the exposure recess.

### Claim 7 (depends on 1)

The medical test slide unit of claim 1, wherein each of the plurality of position indicating markers is formed as a through hole.

### Claim 8

A medical test slide unit comprising a frame main body, wherein the frame main body comprises:
a marker part having a thin plate shape and comprising a plurality of position indicating markers formed longitudinally and transversely;
a border part surrounding the marker part, wherein a step is formed between the border part and the marker part to form a seating recess; and
a slide comprising a specimen to be examined using a microscope, wherein the slide is selectively situated in the seating recess,
wherein the border part comprises a rail groove for facilitating coupling and separation of the border part and the marker part by guiding movement of the marker part.
