55
Q

Principle of Gel Technology

A

Hemagglutination

56
Q

Incubation for Gel Technology, how many minutes?

A

15 minutes

57
Q

Centrifugation for Gel Technology, how many minutes?

A

10 minutes

58
Q

Major Advantage of Gel Technology

A

Standardization since there is n tube shaking to resuspend the RBC button.

59
Q

Major Disadavantage of Gel Technology

A

sample restrictions and the need for special equipment such as centrifuge, incubator, pipette.

60
Q

(GEL TECHNOLOGY GRADING REACTIONS)

Solid band of agglutinated red cells at the top of the gel column. Usually no red cells are visible in the bottom of the microtube.

61
Q

(GEL TECHNOLOGY GRADING REACTIONS)

Predominant amount of agglutinated red cells towards the top of the gel column with a few agglutinates staggered below the thicker band. The majority of agglutinates are observed in the top half of the gel column.

62
Q

(GEL TECHNOLOGY GRADING REACTIONS)

Red cell agglutinates disperesed throughout the gel column with few agglutinates at the bottom of the microtubes. Agglutinates should be distributed though the upper and lower halves of the gel.

63
Q

(GEL TECHNOLOGY GRADING REACTIONS)

Red cell agglutinates predominantly observed in the lower half of the gel column with red cells also in the bottom. These reactions may be weak, with a few agglutinates remaining in the gel area just above the red cell pallet in the bottom of the microtube.

64
Q

(GEL TECHNOLOGY GRADING REACTIONS)

Red cells forming a well-delineated pellet in the bottom of the microtube. The gel above the red cells pellet is clear and free of agglutinates.

65
Q

(GEL TECHNOLOGY GRADING REACTIONS)

Layer of red cell agglutinates at the top of the gel column accompanied by a pellet of unagglutinated cells in the bottom of the microtube.

A

Mixed-Field

66
Q

how many days is the reactions (for gel technology) stable for observation or review?

A

2 - 3 days
